MATERIALS AND METHODS: Twelve respondents from three major ethnicities in Malaysia were selected from the quantitative study on dietary pattern and colorectal cancer carried out earlier in this study. In-depth interviews (IDI), conducted from April until June 2012, were mainly in the Malay language with additional use of English and continued until the saturation point was reached. All interviews were autorecorded so that verbatim transcriptions could be created.
RESULTS: Causes of colorectal cancer were categorized into internal and external factors. The majority of respondents agreed that there is an association between Western foods and colorectal cancer. Malaysian traditional diet was not related to colorectal cancer as less preservative agents were used. Malaysian diet preparation consisting of taste of cooking (spicy, salty and sour foods) plus type of cooking (fry, grilled and smoked) were considered causes of colorectal cancer. All respondents changed their dietary pattern to healthy food after being diagnosed with colorectal cancer. Advice from doctors regarding suitable food for colorectal cancer was useful in this regard.
CONCLUSIONS: Eating outside, use of food flavoring ingredients and preservative agents were considered to be the main factors causing colorectal cancer. All respondents admitted that they changed to a healthy diet after being diagnosed with colorectal cancer.
METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews was utilized in this study. Using predetermined keywords, a systematic search was conducted on three electronic databases from 2005 to 2023, namely, Web of Science, Scopus, and PubMed. Articles written in English, and studies focusing on the research question are among the inclusion criteria. Ten articles were extracted that were relevant to the research question.
RESULTS: Poor socioeconomic status, urban areas, the influence of neighborhood, greenness, and air pollution had associations with mental health status among T2DM patients.
CONCLUSION: The possible implications of these factors for mental health demand further research and policy consideration.
METHODS: Data collection was carried out from November 2017 until May 2018 among 211 Orang Asli respondents aged 18 years old and above, who lived in five villages in Tasik Chini, Pahang. All respondents who fulfilled the inclusion criteria were recruited in this study. Interview-guided questionnaire was administered, and spirometry test that include Forced Expiratory Volume in one second (FEV1), Forced Vital Capacity (FVC), and Peak Expiratory Flow Rate (PEFR) was carried out. Data were analyzed using SPSS software version 23.0. In the first stage, descriptive analysis was done to describe the characteristics of the respondents. In the second stage, bivariable analysis was carried out to compare proportions. Finally, multiple logistic regression was performed to assess the effects of various independent predictors on spirometry parameters.
RESULTS: The respondents' age ranged from 18 to 71 years old in which 50.2% of them were female. The majority ethnicity in Tasik Chini was Jakun tribe (94.3%). More than half of the respondents (52.1%) were current smoker, 5.2% were ex-smoker and 41.7% were non-smoker. More than half of them (62.1%) used woodstove for cooking, compared to only 37.9% used cleaner fuel like Liquefied Petroleum Gas (LPG) as a fuel for everyday cooking activity. The lung function parameters (FEV1 and FVC) were lower than the predictive value, whereas the ratio of Forced Expiratory Volume in one second and Forced Vital Capacity (FEV1/FVC) (%) and PEFR were within the predictive value. The FEV1 levels were significantly associated with age group (18-39 years old) (p = 0.002) and presence of woodstove in the house (p = 0.004). FVC levels were significantly associated with presence of woodstove in the house (p = 0.004), whereas there were no significant associations between all factors and FEV1/FVC levels.
CONCLUSIONS: FEV1 levels were significantly associated with age group 18-39 years old, whereas FVC levels were significantly associated with the presence of woodstove in the house. Thus, environmental interventions such as replacing the use of woodstove with LPG, need to be carried out to prevent further worsening of respiratory health among Orang Asli who lived far from health facilities. Moreover, closer health monitoring is crucial especially among the younger and productive age group.
