Introduction: Childhood obesity is increasing in prevalence in Malaysia. Excess in dietary intake and inadequate physical activity contribute to the development of obesity among children. The objective of this study was to de-termine the association between eating behaviour and excess weight among primary school children in an urban community in Malaysia. Methods: This is a baseline data of a randomized control field trial of a family-based inter-vention to reduce adiposity in overweight and obese children. It involved five primary government schools in Bandar Baru Bangi, Selangor. The inclusion criteria include parent-child dyad; children aged 7 to 10 years with body mass index (BMI) z-score of +1 standard deviation or more. Parents completed the validated self-administered Children Eating Behaviour Questionnaire (CEBQ). This questionnaire assessed children’s eating behaviour that includes food responsiveness, enjoyment of food, emotional overeating, desire to drink, slowness in eating, satiety responsiveness, emotional undereating and food fussiness. The children’s weight and height were measured and the BMI z-score was calculated. The association between CEBQ subscales and obesity was assessed using multiple linear regression, adjusted for sex and family income. Results: One hundred and thirty-four parent-child dyads had participated in this study. The food responsiveness was found to be significant with excess weight (β = 0.094, 95% CI: 0.02-0.17, p= 0.014). Conclusion: The food responsiveness subscale was associated with excess weight. This eating behaviour need to be taken into consideration in the development and implementation of health campaign targeted at the re-duction of childhood obesity.

Cancers of the oral cavity are more common worldwide in men than in women, and the same is true for cancer of the nasopharynx region, whereby nasopharyngeal carcinoma (NPC) incidence rate in men is 2.5 times that in women. Different risk factors, including environmental, lifestyle and genetic factors, come into play in terms of contributing towards the development of these cancers. The increased incidence of oral cancers in developed countries in recent years are attributable to rises in the consumption of tobacco and/or alcoholic beverages, in addition to the traditional practice of betel quid chewing in some communities. As for NPC, the risk factors include male sex, overconsump-tion of preserved salted fish and smoking. In terms of etiology due to microbial agents, the human papillomavirus (HPV) has been linked with oral cancers whereby HPV DNA was found in about 2 out of 3 oropharyngeal cancer cases. In contrast, the Epstein-Barr virus (EBV) has been closely associated with most cases of NPC. Specifically, NPC is categorized by the WHO into two main histological types—keratinizing squamous cell carcinoma (type I) and non-keratinizing squamous cell carcinoma (types II and III), and it is the non-keratinizing type (types II and III) which has very high percentage of EBV DNA. The oncogenicity of these viruses had been studied extensively, and they are now recognized as crucial early triggers of NPC and oral cancers. Genetic factors can also predispose a person to the development of either oral cancer or NPC. Certain HLA class I alleles are associated with increased risks for NPC. Genetic polymorphisms in genes encoding the cytochrome P450 enzymes and glutathione S-transferase had been identified as potential risk factors for NPC. In our studies, we had shown that polymorphism in the XPD gene which encodes a DNA helicase enzyme involved in nucleotide excision repair was linked to risk for NPC in Malaysian population. We also found that the combination of CGC allele from hOGG1, ITGA2 and XPD polymorphisms was significantly associated with increased odds of NPC. In oral cancers, studies by other researchers revealed that gene polymorphisms in HOTAIR gene and the interaction with betel quid chewing are linked to oral cancer risk. Specific COX-2 gene polymorphisms were also found to be associated with increased risk for oral cancer development and progression. Taken together, these studies show a strong correlation between viral etiology combined with the indi-vidual’s genetic background coupled with certain risky lifestyle behaviours which together contribute towards the development of oral cancer and NPC.

Introduction: Tuberculosis is the commonest cause of death among HIV patients in Nigeria. Though tuberculosis is common among HIV patients, their knowledge about transmission and prevention is poor. Objective: To determine knowledge, attitude and preventive practices regarding tuberculosis and its predictors among HIV patients receiving treatment. Methods: A cross sectional study was carried out involving 226 randomly selected HIV patients receiving care at General Hospital, Minna. Study duration was from June 2015 to July 2017. Data on socio-demographic characteristics, psychosocial factors, knowledge, attitude and preventive practices regarding tuberculosis was collected using a self-administered, WHO modified, pretested and validated questionnaires. Data collected was analysed using SPSS version 22. Results: Out of 226 respondents, 60(26.5%) had poor knowledge, 123(54.4%) had negative attitude and 48(21.2%) had poor preventive practices regarding tuberculosis. The predictors of knowledge were age (B=0.087, 95%CI=0.031, 0.143, p=0.002), depression (B=-0.444, 95%CI=-0.673,-0.214, p

BACKGROUND: Knowledge of hepatitis B and C has been reported to be low among respondents in different studies. We conducted a cross-sectional study among international students of Universiti Putra Malaysia (UPM) to ascertain their levels of knowledge, attitude and practices regarding hepatitis B and C and its associated factors.
METHODS: Six hundred and sixty two (662) international students participated in this study. A cluster sampling method was employed and data was generated using self-administered questionnaire, which was validated and its reliability checked.
RESULTS: Normality test was conducted followed by descriptive statistics, spearman's correlation and Chi-square tests to explore associations between variables in the study. The response rate was 71.49 %. Of these, 50.3 % of the respondents had better knowledge of hepatitis B; 52.7 % had better knowledge of hepatitis C; 54.8 % had positive attitude towards hepatitis B and C and 77.6 % had safer practices towards hepatitis B and C. Positive correlations were found between knowledge of hepatitis B and knowledge of hepatitis C; knowledge hepatitis B and attitude; knowledge hepatitis C and attitude; knowledge hepatitis B and practice; knowledge hepatitis C and practice; and attitude and practice regarding hepatitis B and C. Similarly, some socio-demographic variables and history of hepatitis were found to be associated with knowledge, attitude and practice related to hepatitis B and C.
CONCLUSION: The levels of knowledge and attitude towards hepatitis B and C were low among respondents but majority of them exhibited safe practices. The study level, faculty, age, nationality, marital status and gender of the respondents were significantly associated with their levels of knowledge, attitude and practices towards the disease. These findings imply that there is need for hepatitis health promotion among the international students of UPM and possibly other international students across the globe. It will serve to improve their levels of knowledge, attitude and practices in short term and get them protected against the disease in the long run.
