    PMID: 20578555
    Allergy to different classes of mollusks, including squid, which are members of the class Cephalopods has been reported. Tropomyosin, a major muscle protein, is the only well-recognized allergen in squid. The aim of this study was to characterize IgE-binding proteins of local Loligo edulis (white squid) consumed in Malaysia. Protein profiles and IgE-binding proteins were detected by sodium dodecyl sulfate-polyacrylamide gel-electrophoresis (SDS-PAGE) and immunoblotting using sera from 23 patients with positive skin prick test to raw squid extract. SDS-PAGE of the raw extract exhibited 21 protein bands (10-170 kDa) but those ranging from 19 to 29 kDa and 41 to 94 kDa were not found in the cooked extract. Immunoblotting of raw extract demonstrated 16 IgE-binding bands, ranging from 13 to 170 kDa. A heat-resistant 36 kDa protein, corresponding to squid tropomyosin, was identified as the major allergen of both extracts. In addition, a 50 kDa heat-sensitive protein was shown to be a major allergen of the raw extract. Our findings indicate that the allergen extract used for diagnosis of squid allergy should contain both the 36 kDa and 50 kDa proteins.

    Golam F, Prodhan ZH
    J Sci Food Agric, 2013 Feb;93(3):449-56.
    PMID: 23238771 DOI: 10.1002/jsfa.5983
    Kernel elongation after cooking is an important character of fine rice and most rice consumers prefer length-wise elongation. Although improvement of aromatic rice began early in the 1970s, until now the mechanisms and genetics of kernel elongation has remained unrevealed. Kernel elongation is considered as a physical phenomenon and is influenced by several physicochemical and genetic factors, including genotypes, aging temperature, aging time, water uptake, amylose content and gelatinization temperature. Recently the complete genetic map of fine rice has been created and the gene responsible for kernel length identified; moreover, this gene is tightly linked with the cooked kernel elongation trait. Several molecular markers linked with cooked kernel elongation have been developed. These tools will be helpful for the improvement of this important trait. For the proper study of cooked kernel elongation of rice, this review paper will provide the basis and directional materials for further studies.

    An experimental nanosilver-coated low-density polyethylene (LDPE) food packaging was incubated with food simulants using a conventional oven and tested for migration according to European Commission Regulation No. 10/2011. The commercial LDPE films were coated using a layer-by-layer (LbL) technique and three levels of silver (Ag) precursor concentration (0.5%, 2% and 5% silver nitrate (AgNO3), respectively) were used to attach antimicrobial Ag. The experimental migration study conditions (time, temperature and food simulant) under conventional oven heating (10 days at 60°C, 2 h at 70°C, 2 h at 60°C or 10 days at 70°C) were chosen to simulate the worst-case storage period of over 6 months. In addition, migration was quantified under microwave heating. The total Ag migrant levels in the food simulants were quantified by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). Mean migration levels obtained by ICP-AES for oven heating were in the range 0.01-1.75 mg l(-1). Migration observed for microwave heating was found to be significantly higher when compared with oven heating for similar temperatures (100°C) and identical exposure times (2 min). In each of the packaging materials and food simulants tested, the presence of nanoparticles (NPs) was confirmed by scanning electron microscopy (SEM). On inspection of the migration observed under conventional oven heating, an important finding was the significant reduction in migration resulting from the increased Ag precursor concentration used to attach Ag on the LDPE LbL-coated films. This observation merits further investigation into the LbL coating process used, as it suggests potential for process modifications to reduce migration. In turn, any reduction in NP migration below regulatory limits could greatly support the antimicrobial silver nanoparticle (AgNP)-LDPE LbL-coated films being used as a food packaging material.

    Babji AS, Alina AR, Seri Chempaka MY, Sharmini T, Basker R, Yap SL
    Int J Food Sci Nutr, 1998 Sep;49(5):327-32.
    PMID: 10367001
    Four formulations of burgers, prepared with 65% lean meat and 15% fat consisting of RBD palm stearin (PS), Socfat 4000P and Socfat 4100P and beef fat (BF) as control were evaluated for solid fat content (SFC), slip melting point (SMP), cooking loss, proximate analysis (moisture, fat and protein), colour, i.e. lightness ('L'), redness ('a') and yellowness ('b'), free fatty acid (FFA), iodine value (IV), thiobarbituric acid (TBA) and texture profile analysis (TPA). Sensory evaluation was carried out for texture, juiciness, aroma, oiliness and overall acceptance. SFC and SMP for raw and cooked SF4000P beef burgers were closest to BF control burgers, falling into the range of 35-40 degrees C. Cooking loss was highest for PS burgers, there were no significant differences (P > 0.05) amongst BF, SF4000P and SF4100P burgers. Proximate analysis on raw burgers showed SF4000P to contain high fat and lowest moisture contents. Objective textural measurements using texture profile analysis (TPA) for all cooked burgers showed no significant differences (P > 0.05) for springiness and cohesiveness. Variation of values among the formulations for hardness, gumminess and chewiness are explained by the differences of SFC for beef burgers with various types of fats. Raw and cooked PS burgers have the lightest 'L' values compared with other fat-substituted burgers while BF, SF4000P and SF4100P indicated no significant differences (P > 0.05) for 'L', 'a' and 'b' values. Beef fat showed the highest amount of free fatty acids (FFA) compared to palm oil samples. For the iodine value (IV), SF4000P showed the highest value which means that it contained the highest level of unsaturated fatty acids followed by PS, BF and SF4100P successively. SF4000P had the highest TBA values followed successively by BF, PS and SF4100P. For sensory evaluation, PS burgers had the least oily taste. This may be due to its high cooking loss. Taste panelists could not differentiate burgers with substituted vegetable fats against the control burgers.

  5. Alkyl amides and nitriles as novel tracers for biomass burning
    Rushdi AI, bin Abas MR, Didyk BM
    Environ Sci Technol, 2003 Jan 1;37(1):16-21.
    PMID: 12542285
    The occurrence of n-alkanoic acids, amides, and nitriles in samples of aerosol particulate matter from Kuala Lumpur and Santiago suggests that emissions from cooking and biomass burning are the primary sources of these organic markers in the atmosphere. It is proposed that fatty acids react with ammonia during biomass burning or combustion to produce amides and nitriles, which can be applied as useful biomarker tracers. To test this hypothesis, nonadecanoic acid and hexadecanamide were used as reactants in hydrous pyrolysis experiments. These experiments produced amides and nitriles and indicated that ammonia is an essential agent in their formation. Thus amides and nitriles are of utility as indicators for input from combustion and biomass burning in the ambient atmosphere.

    Food related disease or food poisoning is prevalent worldwide and is associated with high mortality. It can be caused by bacteria, viruses, parasites, enterotoxins, mycotoxins, chemicals, histamine poisoning (scombroid) ciguatera and harmful algal bloom (HAB). Illness can also result by red tide while breathing in the aerosolized brevitoxins (i.e. PbTx or Ptychodiscus toxins). Bacterial toxin food poisoning can affect within 1-6 hours and 8-16 hours, and illness can be with or without bloody diarrhea. The common symptoms of food poisoning include abdominal cramps, vomiting and diarrhea. Diagnosis includes examination of leftover food, food preparation environment, food handlers, feces, vomitus, serum and blood. Treatment involves oral rehydration, antiemetic, and anti-peristaltic drugs. Antimicrobial agents may be needed in the treatment of shigellosis, cholera, lifesaving invasive salmonellosis and typhoid fever. Proper care in handling and cooking is important to prevent any food borne diseases.

  7. Analysis of volatile flavour compounds and acrylamide in roasted Malaysian tropical almond (Terminalia catappa) nuts using supercritical fluid extraction
    Lasekan O, Abbas K
    Food Chem Toxicol, 2010 Aug-Sep;48(8-9):2212-6.
    PMID: 20510332 DOI: 10.1016/j.fct.2010.05.050
    Considering the importance of tropical almond nuts as a snack item, a study was conducted to identify the flavour volatiles and acrylamide generated during the roasting of the nuts. The supercritical fluid extracted flavour components revealed 74 aroma active compounds made up of 27 hydrocarbons, 12 aldehydes, 11 ketones, 7 acids, 4 esters, 3 alcohols, 5 furan derivatives a pyrazine, and 2 unknown compounds. While low levels of acrylamide (8-86 microg/kg) were obtained in the roasted nuts, significant (P<0.05) increases occurred in concentration with increased roasting temperature and time. Carboxylic acids were the most abundant volatiles in the roasted almond nuts and less significant (P>0.05) concentration of acrylamide was generated with mild roasting and shorter roasting period.

  8. Valorization of biodiesel side stream waste glycerol for rhamnolipids production by Pseudomonas aeruginosa RS6
    Baskaran SM, Zakaria MR, Mukhlis Ahmad Sabri AS, Mohamed MS, Wasoh H, Toshinari M, et al.
    Environ Pollut, 2021 Feb 13;276:116742.
    PMID: 33621735 DOI: 10.1016/j.envpol.2021.116742
    Biodiesel side stream waste glycerol was identified as a cheap carbon source for rhamnolipids (RLs) production which at the same time could improve the management of waste. The present study aimed to produce RLs by using Pseudomonas aeruginosa RS6 utilizing waste glycerol as a substrate and to evaluate their physico-chemicals properties. Fermentation conditions such as temperature, initial medium pH, waste glycerol concentration, nitrogen sources and concentrations resulted in different compositions of the mono- and di-RLs produced. The maximum RLs production of 2.73 g/L was obtained when P. aeruginosa RS6 was grown in a basal salt medium supplemented with 1% waste glycerol and 0.2 M sodium nitrate at 35 °C and pH 6.5. At optimal fermentation conditions, the emulsification index (E24) values of cooking oil, diesel oil, benzene, olive oil, petroleum, and kerosene were all above E24=50%. The surface tension reduction obtained from 72.13 mN/m to 29.4-30.4 mN/m was better than the surface activity of some chemical-based surfactants. The RLs produced possessed antimicrobial activities against Gram-negative and Gram-positive bacteria with values ranging from 37% to 77% of growth inhibition when 1 mg/mL of RLs was used. Concentrations of RLs below 1500 μg/mL did not induce phytotoxicity effects on the tested seeds (Vigna radiata) compared to the chemical-based- surfactant, SDS. Furthermore, RLs tested on zebrafish (Danio rerio) embryos only exhibited low acute toxicity with an LC50 value of 72.97 μg/mL at 48 h of exposure suggesting a green and eco-biochemical worthy of future applications to replace chemical-based surfactants.

  9. Fulltext Long-term exposure to outdoor and household air pollution and blood pressure in the Prospective Urban and Rural Epidemiological (PURE) study
    Arku RE, Brauer M, Ahmed SH, AlHabib KF, Avezum Á, Bo J, et al.
    Environ Pollut, 2020 Jul;262:114197.
    PMID: 32146361 DOI: 10.1016/j.envpol.2020.114197
    Exposure to air pollution has been linked to elevated blood pressure (BP) and hypertension, but most research has focused on short-term (hours, days, or months) exposures at relatively low concentrations. We examined the associations between long-term (3-year average) concentrations of outdoor PM2.5 and household air pollution (HAP) from cooking with solid fuels with BP and hypertension in the Prospective Urban and Rural Epidemiology (PURE) study. Outdoor PM2.5 exposures were estimated at year of enrollment for 137,809 adults aged 35-70 years from 640 urban and rural communities in 21 countries using satellite and ground-based methods. Primary use of solid fuel for cooking was used as an indicator of HAP exposure, with analyses restricted to rural participants (n = 43,313) in 27 study centers in 10 countries. BP was measured following a standardized procedure and associations with air pollution examined with mixed-effect regression models, after adjustment for a comprehensive set of potential confounding factors. Baseline outdoor PM2.5 exposure ranged from 3 to 97 μg/m3 across study communities and was associated with an increased odds ratio (OR) of 1.04 (95% CI: 1.01, 1.07) for hypertension, per 10 μg/m3 increase in concentration. This association demonstrated non-linearity and was strongest for the fourth (PM2.5 > 62 μg/m3) compared to the first (PM2.5

    Introduction: Chronic obstructive pulmonary disease (COPD) patients usually have dietary problems leading to malnutrition issues. Therefore, this study aimed to determine macro and micronutrient intakes and meal-related sit- uations among outpatients COPD elderly and its adequacy according to their requirements. Methods: 140 patients were included in this cross-sectional study at Respiratory Clinics of Hospital Serdang and Institut Perubatan Respira- tori. Socio-demographic and health status data were collected by interviewing patients and reviewing their medical records. A three-day diet history (two-day on weekdays, one day on weekend) was analysed using Nutritionist Pro and compared against their requirements. Meal-related situation was assessed using three open-ended questions that related to food shopping, cooking and eating and analysed using content analysis. Results: Patients were 70±7 years old, 97% male, 59% Malay, 48% had primary education, 75% married, 72% ex-smokers and 54% presented with comorbidities. Majority of them had no episode of exacerbation for the past one year and in moderate stage of the COPD severity. Mean energy intake was 916±221 kcal/day with 98% of them have under-reported their intake. Almost all patients had inadequate macro and micronutrient intake; energy (97%), protein (97%), carbohydrate (86%), fat (99%), vitamin A (95%), C (86%), D (99%) and E (99%). The meal-related situation reported patients had difficulties with food shopping and preparation and problems during mealtime. Conclusion: COPD elderly reported inadequate intake of macro and micronutrients and had problems during mealtime. This indicates the need for Ma- laysian nutrition guidelines specific to COPD patients and nutrition intervention in the primary setting.

  11. Optimization of soy protein isolate, microbial transglutaminase and glucono-δ-lactone in gluten-free rice noodles
    Ojukwu M, Ofoedu C, Seow EK, Easa AM
    J Sci Food Agric, 2021 Jul;101(9):3732-3741.
    PMID: 33301191 DOI: 10.1002/jsfa.11004
    BACKGROUND: Rice flour does not contain gluten and lacks cohesion and extensibility, which is responsible for the poor texture of rice noodles. Different technologies have been used to mitigate this challenge, including hydrothermal treatments of rice flour, direct addition of protein in noodles, use of additives such as hydrocolloids and alginates, and microbial transglutaminase (MTG). Recently, the inclusion of soy protein isolate (SPI), MTG, and glucono-δ-lactone (GDL) in the rice noodles system yielded rice noodles with improved texture and more compact microstructure, hence the need to optimize the addition of SPI, MTG, and GDL to make quality rice noodles.

    RESULTS: Numerical optimization showed that rice noodles prepared with SPI, 68.32 (g kg-1 of rice flour), MTG, 5.06 (g kg-1 of rice flour) and GDL, 5.0 (g kg-1 of rice flour) gave the best response variables; hardness (53.19 N), springiness (0.76), chewiness (20.28 J), tensile strength (60.35 kPa), and cooking time (5.15 min). The pH, sensory, and microstructure results showed that the optimized rice noodles had a more compact microstructure with fewer hollows, optimum pH for MTG action, and overall sensory panelists also showed the highest preference for the optimized formulation, compared to other samples selected from the numerical optimization and desirability tests.

    CONCLUSION: Optimization of the levels of SPI, MTG, and GDL yielded quality noodles with improved textural, mechanical, sensory, and microstructural properties. This was partly due to the favourable pH value of the optimized noodles that provided the most suitable conditions for MTG crosslinking and balanced electrostatic interaction of proteins. © 2020 Society of Chemical Industry.

  13. Fulltext Omega-3 fatty acids: potential sources in the Malaysian diet with the goal towards achieving recommended nutrient intakes
    Ng, T.K.W.
    Malays J Nutr, 2006;12(2):181-188.
    MyJurnal
    Omega-3 fatty acid nutrition is widely recognised as essential to health and general well-being. However, health professionals and the general public in Malaysia may lack knowledge on the sources or the amounts of these essential fat components in foods. This paper attempts to correct this scenario by identifying the potential sources of omega-3 fatty acids [a-linolenic acid (ALA), or eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA)] in the Malaysian diet and calculating the amounts of these “nutrients” provided per serving of a wide variety of foods. The information generated provides Malaysian health professionals and consumers with options in food choices or meal planning with the goal towards achieving the recommended nutrient intakes for omega-3 fatty acids. The findings in the present study revealed that the potential sources of omega-3 fatty acids in the Malaysian diet in decreasing order are: edible oils (ALA), fish and fish products (EPA+DHA), vegetables (ALA), meat and eggs (EPA+DHA), and milk/milk products (EPA+DHA). Edible oils which are exceptionally high in ALA such as flaxseed oil and perilla oil are presently unavailable at local retail outlets and supermarkets. However, consumers can still meet the recommended nutrient intakes (RNIs) for omega-3 fatty acids of 0.3 to 1.2% energy (equivalent to 0.67g-2.67g) by choosing a wellbalanced diet prepared preferably with a cooking oil blend containing ALA, and one or more servings daily from at least three of the following food groups: (i) fish (“jelawat”, “siakap”, sardines, tuna, mackerel, salmon)/seafoods (shrimps, crab)/meat, (ii) vegetables/soybean/ soybean-based products/beans and peas, (iii) omega-3 enriched/fortified foods (eg. “omega-3 eggs”), and (iv) ready-to-drink omega-3 milk preparations/soybean milk.

    This study was conducted to determine the effects of increased edible palm oil consumption on community health status in the aboriginal communities in Tual Post (treatment group) and Sinderut Post (control group), Kuala Lipis, Pahang. Nutritional status, blood pressure, lipid profiles, fasting blood glucose (FBG), vitamin E (alpha-tocopherol) levels and lipid peroxidation product (malonaldehyde) levels were taken as indicators of health status. This is a pre-and post-controlled community trial in which similar variables were measured in each group. Every family of 2–6 household members was given 2–5 kg cooking palm oil per month for a period of 18 months. All subjects were measured for height (cm), weight (kg) and waist-hip ratio (WHR). For calorie intake measurement, house-to-house interviews were conducted using 24-hour dietary recall method. Blood pressure, percent body fat, lipid profiles, namely total cholesterol, high density lipoprotein cholesterol, triglyceride and fasting blood glucose (FBG) were also measured. Vitamin E (alpha-tocopherol) levels and lipid peroxidation products (MDA) were also determined. There was a significant increase (p

  15. Fulltext Dietary Fat and Fibre Intakes of Malaysian Adults: Issues and Implications when ‘Western Targets’ Are Set as Dietary Goals
    Malays J Nutr, 1997;3(2):-.
    MyJurnal
    This article examines the fat and fibre intakes of Malaysian adults and highlights discrepancies and practical limitations if these intakes are to match the levels for these nutrients advocated in the World Health Organisation (WHO) and American Heart Association (AHA) ‘diet models’. Local data on food consumption showed that the total fat intakes amongst Malaysian adults, contrary to common perception, were not high and the mean values obtained fell within the range of 40-66g or 22-26% kcal. As such, the dietary target of 30% kcal total fat or its intermediate target of 30-35% kcal, advocated by WHO and AHA mainly to address the problem of a high consumption of dietary fats in western populations, should not be adopted indiscriminately by Malaysians. Dietary fatty acid (FA) analysis by high performance liquid chromatography (HPLC) coupled with the use of food composition tables, showed that the typical Malaysian diet prepared with palm olein or palm olein-groundnut oil blends as cooking oil contained 3.2-4.0% kcal polyunsaturated fatty acids (PUFA), mainly as the w-6 linoleic acid, which is also the predominant essential fatty acid (EFA) in humans. This level of linoleic acid, with an ω-6/ ω--3 FA ratio approximating 10, is adequate for basal PUPA and EFA needs but fell short of the 4-10% kcal linoleic acid recommended by WHO (1993) to counter the effects of the cholesterol-raising saturated fatty acids (SFA). This raised upper limit of 10% kcal linoleic acid (previously 7% kcal), which equals the level of PUFA implied in the AHA diet model, appears unnecessarily high considering that the cholesterol-lowering potential of linoleic acid is maximum at about 6% kcal, while the health hazards associated with long-term high intakes of PUPA have never been completely dismissed. The new WHO lower limit for dietary linoleic acid (4% kcal) would have a controversial impact of raising the previous minimal 3% kcal EFA to above 4% kcal (linoleic + alpha-linolenic acids). Similarly, the WHO recommendation for total dietary fibre of 27-40g (equivalent to a daily combined intake of 400g of vegetables and fruits, 30g of which should come from pulses) appears at present, too high a dietary target for the average Malaysian adult whose habitual daily diet was estimated to contain about 180g of vegetables plus fruits, providing only about 13-16g total dietary fibre. Appropriately, an expert panel on Malaysian Dietary Guidelines has recommended instead, 20-30% kcal total fat containing 3-7% kcal PUFA, and 20-30g total dietary fibre for the local population.

    MyJurnal
    Ulam or traditional vegetables in Malaysia comprise more than 120 species representing various
    families ranging from groundcovers, shrubs to trees. The leaves, shoots, flowers, fruits, roots and rhizomes of the vegetables are eaten fresh as salad or cooked and are consumed to add variety and flavor to the diet, as well as for their health benefits. Ulam species are rich in carbohydrate, protein, mineral and vitamin. This study established that ulam species differ greatly with respect to types and concentrations of carotenoids in leaves. A total of 10 species were evaluated for quantitative and qualitative carotenoid composition through spectrophotometry and HPLC analysis. The main carotenoids identified in these selected ulam were lutein, neoxanthin, violaxanthin, zeaxanthin and β-carotene. The ratio of these carotenoids varies between species.

    Escherichia coli O157:H7 is a major food-borne pathogen that has resulted in numerous
    outbreaks around the world. Widespread distribution of the organism in various ecological
    niches impedes the control measures. This study aimed to detect and quantify E. coli O157:H7
    in beef sold in wet markets and hypermarkets in Malaysia and to determine the risk of E. coli
    O157:H7 infection linked to consumption of beef. The rfbO157 and flicH7 primers targeted on
    somatic antigen (O157) and flagellar antigen (H7) respectively of E. coli O157:H7 was used for
    the MPN-PCR method. A total of 99 beef samples were collected from local wet markets and
    hypermarkets. The highest E. coli O157:H7 contamination rate was observed in beef samples
    collected from wet markets (89.50%), whereas the contamination rate in hyper market A and B
    were compratively low (35.35 and 20% respectively). However, the microbial load was highest
    in the beef samples from hypermarket A (1100 MPN/g) while E. coli O157:H7 bacterial load
    in beef samples from hypermarket B and wet market ranged from 3 to 93 MPN/g and 3 to 240
    MPN/g, respectively. Using the Quantitative Microbial Risk Assessment (QMRA) approach
    the risk was estimated incorporating the findings of the prevalence study and predictions
    based on home storage, cooking and consumption patterns. Three different exposure pathways
    were investigated to estimate the risk associated with contaminated beef and Monte Carlo
    simulation was used to determine the level of uncertainty. The developed model predicated that
    consumption of contaminated beef can be accountable for 1.83E+06 E. coli O157:H7 cases per
    year in Malaysia. The reliability of the model, data gaps and further research needs, is discussed.
    Through continuous improvement Quantitative Microbial Risk Assessment provides valuable
    insight into controlling and prevention strategies.

  18. Comparative Evaluation of Dental and Skeletal Fluorosis in an Endemic Fluorosed District, Salem, Tamil Nadu
    Ramesh M, Malathi N, Ramesh K, Aruna RM, Kuruvilla S
    J Pharm Bioallied Sci, 2017 Nov;9(Suppl 1):S88-S91.
    PMID: 29284943 DOI: 10.4103/jpbs.JPBS_77_17
    Background: High levels of fluoride in the drinking water, especially ground water, results in skeletal fluorosis which involves the bone and major joints. This study was conducted to assess the prevalence of skeletal fluorosis to compare with dental fluorosis in an endemically fluorosed population in the District of Salem, Tamil Nadu.

    Materials and Methods: Institutional ethical clearance was obtained. A total of 206 patients who reported to the Department of Hematology for blood investigations were the participants in this study. Age, sex, place, weight, height, dental fluorosis, and skeletal complaints were noted down. Body mass index was calculated, and statistical analysis was performed.

    Results: Dental fluorosis was present in 63.1% and absent in 36.9% of the samples reported. Skeletal fluorosis was present in 24.8% and was absent in 75.2%. A large number of the patients had knee pain and difficulty in bending. Chi-square test was used for statistical analysis. Skeletal fluorosis and age were compared and P value was 0.00 and was significant. Dental fluorosis and skeletal fluorosis were compared and P value was found to be 0.000 and significant.

    Discussion and Conclusion: There is a need to take measures to prevent dental and skeletal fluorosis among the residents of Salem district. Calcium balance should be maintained, and fluoride intake should be minimized to reduce the symptoms. The government should provide water with low fluoride level for drinking and cooking. Once the symptoms develop, treatment largely remains symptomatic, using analgesics and physiotherapy.

    This cross-sectional study assessed household food insecurity among low-income rural communities and examined its association with demographic and socioeconomic factors as well as coping strategies to minimize food insecurity. Demographic, socioeconomic, expenditure and coping strategy data were collected from 200 women of poor households in a rural community in Malaysia. Households were categorized as either food secure (n=84) or food insecure (n=116) using the Radimer/Cornell Hunger and Food Insecurity instrument. T-test, Chi-square and logistic regression were utilized for comparison of factors between food secure and food insecure households and determination of factors associated with household food insecurity, respectively. More of the food insecure households were living below the poverty line, had a larger household size, more children and school-going children and mothers as housewives. As food insecure households had more school-going children, reducing expenditures on the children's education is an important strategy to reduce household expenditures. Borrowing money to buy foods, receiving foods from family members, relatives and neighbors and reducing the number of meals seemed to cushion the food insecure households from experiencing food insufficiency. Most of the food insecure households adopted the strategy on cooking whatever is available at home for their meals. The logistic regression model indicates that food insecure households were likely to have more children (OR=1.71; p<0.05) and non-working mothers (OR=6.15; p<0.05), did not own any land (OR=3.18; p<0.05) and adopted the strategy of food preparation based on whatever is available at their homes (OR=4.33; p<0.05). However, mothers who reported to borrow money to purchase food (OR=0.84; p<0.05) and households with higher incomes of fathers (OR=0.99; p<0.05) were more likely to be food secure. Understanding the factors that contribute to household food insecurity is imperative so that effective strategies could be developed and implemented.

    Background: We examined whether multidimensional poverty index (MPI) explained variations in life expectancy (LE) better than income poverty; and assessed the relative importance of MPI indicators in influencing LE.

    Methods: Cross-sectional data from 62 developing countries were used to run several multivariate linear regressions. R2 was used to compare the powers of MPI with income-poverties (income poverty gaps [IPG] at 1.9 and 3.1 USD) in explaining LE.

    Results: Adjusting for controls, both MPI (β =-0.245, P<0.001) and IPG at 3.1 USD (β=-0.135, P=0.044) significantly correlates with LE, but not IPG at 1.9 USD (β=-0.147, P=0.135). MPI explains 12.1% of the variation in LE compared to only 3.2% explained by IPG at 3.1 USD. The effect of MPI on LE is higher on female (β=-0.210, P<0.001) than male (β=-0.177, P<0.001). The relative influence of the deprivation indictors on LE ranks as follows (most to least): Asset ownership, drinking water, cooking fuel, flooring, child school attendance, years of schooling, nutrition, mortality, improved sanitation, and electricity.

    Conclusion: Interventions to reduce poverty and improve LE should be guided by MPI, not income poverty indices. Such policies should be female-oriented and prioritized based on the relative influence of the various poverty deprivation indicators on LE.
