A cross-sectional study was carried out in Kota Bharu on three groups of men with ages ranging
from 18 to 44 years. The study groups included 83 athletes representing various types of sports and
levels of participation (athlete group), 80 active men who exercised a minimum of 30 minutes per day
at least 3 times per week (exercise group), and 80 inactive men (sedentary group). The objectives of
the study were to compare the body mass indices (BMIs) and body fat statuses among the three groups
with different physical activity levels. The height and weight of respondents were measured using
the Seca weighing balance with height attachment. Skinfold thickness of biceps, triceps, subscapular
regions, and suprailiac regions of each respondent were measured using Harpenden skinfold calipers.
Percentage body fat was calculated as the sum of the four measurements of skinfold thickness. The
results showed that the mean (± SD) BMIs in the athlete, exercise, and sedentary groups were 22.6 ± 2.9,
23.4 ± 3.5, and 24.3 ± 4.6 kg/m2, respectively. The combined prevalence of pre-obese (BMI 25.029.9)
and obese (BMI ³ 30.0) subjects was 21.7% in the athlete group, 29.9% in the exercise group, and 47.5%
in the sedentary group. The mean (± SD) percentage of body fat in athletes was 15.7 ± 5.4%, which was
lower than in the exercise (18.9 ± 5.5%) and sedentary (20.6 ± 5.8%) groups. The study revealed that
individuals who are actively involved in physical activity, particularly in sport activities, have lower
BMIs and percentage body fat values compared to sedentary people. Therefore, to prevent obesity, all
individuals are encouraged to perform regular physical activity, particularly sports activities.

Introduction: Physical inactivity is the one of the leading causes of major non-communicable
diseases in the world. The aim of this study is to assess the feasibility of an intervention program
based on the stages of change, physical activity levels and health profiles of selected overweight and
obese adults in Sarawak.
Methods: This intervention study was carried out using selected overweight and obese adults in
Sarawak. A total of 75 participants were placed in the intervention group, and 80 respondents were
placed in the control group participated. Respondent-determined weekly aerobic exercise sessions
were conducted for six months. The Malay version of the long-form International Physical Activity
Questionnaire (IPAQ) and Transtheoretical model of change (TTM) questionnaire were used,
together with anthropometric measurements and the collection of venous fasting blood profiles.
Data was entered and analyzed using SPSS Version 20.
Results: The intervention group had significant better stage transitions compared to the control
group (p<0.01). They also had significantly lower total cholesterol, although both groups showed
significant results (difference= 0.53, p<0.01; difference= 0.38, p=0.01). The respondent-determined
intervention program was effective in improving stage transition; however, an intervention of longer
duration could provide more conclusive health outcomes.
Conclusion: Physical activity plays a role in assisting overweight and obese adults to be more active
and healthier.

Underlying causes of most nutrition related problems are diverse, including biological, social, cultural, and economic factors. Qualitative approaches complement quantitative methods in identifying the underlying meanings and patterns of relationships involved in managing malnutrition. This study examined perceptions regarding malnutrition among health workers from 7 clinics (community and health clinics) in Tumpat, Kelantan. A total of 18 nurses and 2 doctors, who were involved in monitoring child health and nutrition, were included in the study. These health workers were interviewed using a semi-structured questionnaire adapted from Sastry’s framework on malnutrition (Sastry, 1996). The questionnaire included biological, behavioral and environmental factors that influence child health and nutrition. All the health workers perceived that mothers/caregivers play the main role in improving the health of malnourished children. The quality of childcare was rated as moderately satisfactory by the health workers. Most of the affected families who were given the Food Baskets did not fully use all the items for the malnourished child. Child feeding practice was based on the needs of the whole family rather than according to the target child’s needs. Most of the mothers preferred processed cereals than rice porridge because the former is easier to prepare for the child. Although they were from a low socioeconomic background, most of the mothers were not earning additional income for the family. The qualitative methodology provided information that can be used as a basis for the designing of quantitative questionnaires to assess malnutrition among children. The induction characteristic of qualitative methods was used to gain an understanding of the underlying reasons or phenomena such as behaviours that are directly observable.

The objective of this study was to describe the differences in physical activity with socio-demographic factors and its association with cardiovascular risk factors. It was a cross-sectional study among selected urban and rural Malays communities in Kuching and Samarahan. Physical activity data was obtained using International Physical Activity Questionnaire (IPAQ) short version. Assessment of cardiovascular risk factors was based on blood pressure, fasting cholesterol and glucose and body mass index (BMI). Data was analysed using SPSS version 20. A total of 223 participated with higher response from rural areas (60.1%) and females (61.9%). More than half of the respondents (58.5%) were overweight and obese, with a mean BMI of 25.9 kg/m2 (SD=4.9). About 25% of the respondents were found to have blood pressure in the at-risk range. The prevalence of at-risk blood glucose was 52.3% with a mean value of 7.3mmol/L (SD=3.46). The prevalence of at-risk cholesterol were lower with 31.8%, mean value of 3.5 mmol/L (SD=2.94). There were more active respondents living in rural area (p=0.02). Logistics regression analysis showed that urban area (OR=1.988 95% CI 1.082 to 3.652), systolic blood pressure (OR1.020 95% CI 1.003 to 1.037) and blood cholesterol (OR0.884 95% CI 0.785 to 0.996) were associated with physical activity level. Change of physical activity due to urbanization can increase the risk of obesity and other chronic diseases. Efforts to include physical activity in intervention programme should be more intensified, with more provision of suitable built environment.

BACKGROUND/OBJECTIVES: The purpose of this study is to utilize an extended Theory of Planned Behavior in identifying predictors of exclusive breastfeeding intention and behavior among women in Kelantan, Malaysia. SUBJECTS/METHODS: A prospective cohort study was conducted, recruiting pregnant womenthrough two-stage cluster sampling. Their exclusive breastfeeding intention, attitude, perceived norm, perceived behavioral control and past behavior were obtained at baseline through interviewer-guided questionnaire. At one month after delivery, another interview was conducted to determine the two additional variables in the extended theory, which were their postpartum support and breastfeeding difficulty. The behavior, which was the actual duration of exclusive breastfeeding, was obtained from the second follow-up at six months. Pearson correlation and two hierarchical regression analyses were conducted. RESULTS: A total of 200 women completed the study follow-up. Their median intended exclusive breastfeeding duration was 4.0 (IQR 5) months, and the median actual duration was 1.0 (IQR 4) month. The Theory of Planned Behavior explained 51.0% of the variance in intention, with perceived behavioral control and attitude were the significant predictors. It also explained 10.0% of the variance in behavior, but the addition of postpartum support and breastfeeding difficulty increased the amount of explained variance in behavior by 6.0%. The significant predictors of exclusive breastfeeding behavior were intention, postpartum support and breastfeeding difficulty. CONCLUSION: The extended Theory of Planned Behaviorhad a good predictive ability in explaining exclusive breastfeedingintention and behavior. The women's intention to practice exclusive breastfeeding may be improved by improving their perceived behavioral control and attitude. Providing correct postpartum support and skills to handle breastfeeding difficulties after delivery will improve their exclusive breastfeeding behavior.

BACKGROUND/OBJECTIVES: Over the past few decades, Malaysia has been experiencing an increased prevalence of overweight and obesity that threatens the health of Malaysians. Poor dietary intake is one of the major contributors to the development of obesity and many non-communicable diseases. The dietary intakes of adults in Malaysia were assessed to determine the association between the dietary intake variables and the body mass index (BMI) and waist circumference (WC) measurements. This study examined whether the dietary intake achieved the recommended nutritional guidelines and compared the intakes between both sexes. SUBJECTS/METHODS: The height, weight, and WC of four-hundred-and-ninety adults (n = 490) in Malaysia were measured using standard procedures. The three-day 24-hour dietary recalls were conducted on 422 out of the 490 adults and their dietary intakes were evaluated in detail. The selected dietary intake variables were used to determine the associations with the obesity indicators. RESULTS: Among the participants, 52.8% were overweight or obese. After data analysis, the mean energy intake was 1,550 kcal/day, in which male participants had a significantly higher energy and macronutrients intake than females. Protein consumption and its percentage of energy contribution exceeded the recommended range. The consumption of fruits, vegetables, and milk and milk products were lower than the recommended number of servings for a healthy diet. The male participants consumed significantly more servings of carbohydrate-based foods, meat, and fats, oils, and sweets than females. Among the selected dietary intake variables, only the carbohydrate intake was negatively associated with the BMI (Estimate b = −0.008) and WC measurements (Estimate b = −0.019) after adjusting for covariates. CONCLUSIONS: This study evaluated the dietary intakes of a sample of Malaysian adults and its association with the obesity indicators. The results highlight the need for improvements and modifications of the dietary intake of Malaysians to reduce the overweight and obesity rates.

BACKGROUND/OBJECTIVES: The purpose of the study was to investigate the relationship between household food insecurity and nutritional status of children in low-income households. A cross sectional study involved a survey of households (n = 223) receiving the financial assistance. SUBJECTS/METHODS: Eligible mothers that fulfilled the inclusion criteria such as non-pregnant, non-lactating mothers, aged 18 to 55 years with their youngest children aged 2 to 12 years, were purposively selected. The Radimer/Cornell hunger and food-insecurity instrument was administered and children's height and weight were measured. RESULTS: About 16.1% of the households were food secure, while 83.9% experienced some kind of food insecurity. Out of food insecure category, 29.6% households were food insecure, 19.3% women were individual food insecure and 35.0% fell into the child hunger category. Education of the mother (P = 0.047), household size (P = 0.024), number of children (P = 0.024), number of children going to school (P = 0.048), total monthly income (P < 0.001), income per capital (P < 0.001), number of household members contributing to the income (P = 0.018) and food expenditure (P = 0.006) were significant risk factors for household food insecurity. The prevalence of underweight, stunting and wasting in children were 61.0%, 61.4% and 30.6% respectively. Based on multinomial logistic regression, children in food-insecure households were 2.15 times more likely to be underweight and three times to be stunted than children in the food-secure households. CONCLUSIONS: The findings suggest that household food insecurity is associated with the nutritional status of the children in the rural area of Northeastern Peninsular Malaysia.

BACKGROUND: A qualitative study providing an in-depth exploration of people's view and the increasing burden of overweight and obesity is required. This study aimed to explore the understanding of dieting and previous experiences on weight loss attempts among overweight and obese government employees in Kelantan, Malaysia, prior to recruitment into the intervention program. METHODS: Thirteen focus group discussions involving 129 participants from a weight-loss intervention program were conducted within the first 1 month of recruitment. These discussions were moderated by two trained researchers in the Malay language and assisted by an interview guide. They were audio-recorded and transcribed verbatim. A thematic analysis was performed, and codes and themes from each discussion were constructed. RESULTS: The participants understood dieting with various meanings, including skipping meals and removing rice from daily diets. They applied numerous methods to lose weight and achieved various outcomes. Health and appearance, social support, and compliance with current trends were the factors motivating these participants to lose weight. Their determination to lose weight was limited by lack of self-control and motivation, experiences of unpleasant effects, influence on weight, and environmental and health factors. CONCLUSION: Real-life weight loss experiences and perceptions provided relevant insights into current weight loss management strategies. Some of these issues and misunderstandings should be emphasized in weight loss strategies during health promotion.

Introduction: Physical activity has been shown to be beneficial for the prevention of obesity and non-communicable diseases. Our contemporary way of life that is technology dependent has significantly reduced physical activity. This study aimed to determine accelerometer-measured physical activity (moderate-to-vigorous physical activity (MVPA)) among adults in high and low walkability neighbourhoods in Penang and Kota Bharu, Malaysia. Methods: Participants (n=490) were sampled using multistage sampling method from neighbourhoods with varied levels of walkability using Geographical Information System (GIS). Physical activity was measured objectively using Actigraph GT3X+ accelerometers, worn by the participants on their waists for a period of 5 to 7 days. Results: The participants had a mean of 13.5 min/day of MVPA. Total MVPA was significantly higher among participants in high walkability neighbourhoods (19.7 min/day vs. 9.1 min/ day). Results from t-test showed that the time spent on MVPA per day was significantly lower among participants residing in low walkability neighbourhoods. The final model of the MIXED model statistical tests showed that total MVPA was significantly associated with BMI, but not with WC measurements, after adjusting for covariates. Conclusion: Most of the participants had very low MVPA and did not achieve the current physical activity recommendations, implying that Malaysian adults residing in these two cities were not physically active to achieve health benefits. Results are suggestive of the importance of the walkability concept in neighbourhoods in encouraging physical activity and healthy body weight among Malaysians.

Introduction: Despite abundant sunshine for cutaneous vitamin D synthesis, low
levels of vitamin D have been documented among the Malaysian population. The aim
of this study was to characterise the effects of occupational sunlight exposure and
monsoon season on serum 25-hydroxyvitamin D [25(OH)D] concentration. Methods:
A comparative cross-sectional study was performed among Malay outdoor (n=119)
and indoor workers (n=119) in Kelantan. Two-point data were collected on the same
participants, first during non-monsoon season and second during the northeast
monsoon season. Data collection comprised of anthropometry measurements (body
mass index and body fat), fasting blood test [serum 25(OH)D concentration], and
questionnaire (physical activity level, sun exposure, sun protection use, and vitamin
D intake). Vitamin D classification was based on the 2011 Endocrine Society Clinical
Practice Guidelines. Results: This study found that serum 25(OH)D concentrations
were significantly higher in outdoor compared to indoor workers irrespective of
season (p<0.001) and sex (p<0.001). Monsoonal differences in serum 25(OH)D
concentration was only observed in male outdoor workers (mean difference=10.39
nmol/l, p<0.001). Significant association between vitamin D status and occupation
was also observed (p<0.001). However, no significant association was found between
vitamin D status and monsoon season [χ2(1)=0.076, p=0.783]. Conclusion: Seasonal
and occupational factors should be considered while evaluating individual serum
25(OH)D concentration and in comparing community studies, especially among
workers.
