The Malaysian Adults Nutrition Survey (MANS) was carried out between October 2002 and July 2003, involving 6,775 men and 3,441 women aged 18 – 59 years.
Anthropometric assessment showed that the overall mean body weight and BMI were 62.65 kg (CI: 62.20, 63.09) and 24.37 kg/m2 (CI: 24.21, 24.53) respectively.
Based on the WHO (1998) classification of BMI, 12.15% (CI: 11.26, 13.10) were obese (BMI > 30 kg/m2), and 26.71% (CI: 25.50, 27.96) overweight (BMI > 25 - 29.9
kg/m2). Significantly, more women were obese [14.66% (CI: 13.37, 16.04)] while
significantly more men were overweight [28.55% (CI: 26.77, 30.40)]. Ethnicitywise,
prevalence of obesity was highest among the Malays [15.28% (CI: 13.91, 16.77)] while overweight was highest for the Indians [31.01% (CI: 26.64, 35.76)].
Both obesity and overweight were highest among those aged 40 - 49 years.
Obesity was highest for those whose household income was between RM1,500 - 3,500 while overweight was more prevalent for those whose household income
exceeded RM3,500. The prevalence of overweight was highest for those with primary education [31.90% (CI: 29.21, 34.72)]. There was no significant urbanrural
differential in both obesity and overweight. The study found 9.02% (CI: 8.82, 10.61) with chronic energy deficiency (CED) (BMI < 18.5 kg/m2). The
prevalence of CED was relatively higher in the indigenous population (Orang Asli) [14.53% (CI: 5.14, 34.77)], subjects aged 18-19 years [26.24% (CI: 21.12, 32.09)],
and with monthly household income of < RM1,500 [10.85% (CI: 9.63, 12.20)]. The prevalence of CED was not significantly different among the geographical zones
and educational levels, and between urban/rural areas and sexes. The results call for priority action to address the serious problem of overweight and obesity
among Malaysian adults as it poses a grave burden to the country’s resources and development.

This study reports the food consumption patterns of adults aged 18 to 59 years in the Malaysian Adults Nutrition Survey (MANS) carried out between October
2002 and December 2003. A total of 6,742 subjects comprising 3,274 men and 3,468 women representing the northern, central , southern and east coast of
Peninsular Malaysia as well as Sabah and Sarawak were interviewed. A semiquantitative
food frequency questionnaire (FFQ) which consisted of 126 food items was used to evaluate the food consumption pattern (habitual food intake) of the respondents during the previous one- year period. The results demonstrate
that nasi putih (cooked rice) was consumed by 97% of the population twice daily (average 2½ plates per day). Other food items consumed daily were marine fish,
(one medium fish per day), green leafy vegetables (one cup per day) and sweetened condensed milk (three teaspoons per day. The mean frequencies for daily intake
of rice, leafy vegetables, marine fish, local kuih, anchovy(ikan bilis) and biscuits were significantly higher among the rural compared to the urban adults. In
contrast, more urban dwellers consumed chicken and eggs more frequently than their rural counterparts. More men than women consumed chicken and eggs
more frequently. Malaysian adults showed a satisfactory habit of drinking plain water, with 99% drinking at least six glasses of plain water daily. Other beverages
such as tea (47%), coffee (28%), chocolate-based drinks (23%) and cordial syrup (11%) were also consumed on daily basis, however, in a smaller proportion of the
population. There were differences in the prevalence of daily consumption of foods when comparing urban and rural population, and also between men and
women. The prevalence of daily consumption of marine fish among rural and urban adults was 51% and 34% respectively. For sweetened condensed milk, men and women consumed 43% and 28% respectively; however, more women
drank full cream milk than men. Between the age groups, 21% of adults below 20 years old consumed chicken at least once a day, while this pattern of intake was
not shown in the older age groups. Our findings show that adults, aged 50 to 59 years old, had the highest prevalence of daily consumption of full cream milk
with 24% while those aged 18 to 19 years old had the lowest prevalence of daily consumption at 15%. The food consumption pattern of Malaysian adults appears
to be satisfactory. However, some changes in food habits are recommended especially in substituting the less wholesome sweetened condensed milk with
the more nutritious full cream or skimmed milk.
