Cardiovascular diseases (CVD) and associated nutritional risk factors are among
the leading causes of mortality and morbidity in both developed and developing
countries. Obesity is an independent risk factor for cardiovascular disease. In
Mongolia, cardiovascular diseases have consistently been the leading cause of
death since 1995. However, there is a lack of study on the relationship between
diet and nutritional risk factors of chronic disease among Mongolians. The
purpose of this study was to identify major dietary patterns of the Mongolian
adults and to examine the dietary patterns as risk factor of overweight and obesity.
Dietary intake is an important determinant of obesity. People consume meals with complex combinations of foods and nutrients. The dietary pattern approach
considers the overall diet of persons by taking into account intakes of combined
foods and nutrients. This approach is increasingly applied in relations to public
health. The cross - sectional study of 420 healthy Mongolian men and women
aged 25 years and over was conducted in urban and rural province of Mongolia.
This Health and Nutrition survey was carried out jointly by the National Public
Health Institute of Mongolia and Kagawa Nutrition University of Japan in 2002
and 2005. Dietary intake was assessed by interview using a semi-quantitative food
frequency questionnaire (FFQ) with 68 items. Anthropometric measurements
were taken and assessed in accordance with WHO guidelines: weight, height,
waist circumference and BMI. Percentage of body fat was measured using a
bioelectrical impedance meter. The Principal Component Factor analysis was
applied to derive dietary patterns. Twenty one (21) food groups were entered into
the factor analysis. Eigenvalue >1.25 criterion and scree plot were used to define
the number of factors. Factor scores in all identified factors were calculated for
each individual person. Logistic regression analysis was used to calculate odds
ratio (OR) and 95% confidence interval (95% CI) for BMI ≥ 25, central obesity
and percentage of body fat categories for each quintile of the dietary pattern. An
exploratory factor analysis resulted in three types of dietary patterns that
accounted for 34.5% of the total variance for the original dietary intake. The
Transitional dietary pattern was characterized by higher intake of pork, sausage,
cheese, beef, mutton, goat, potato, vegetables and cookies. The Traditional dietary
pattern was heavily loaded on milk and milk products, fat and oil, sugar,confectionery and horse meat, whereas the Healthy dietary pattern was high in
egg, barley, whole grain bread, vegetable salad, fruits and rice. Male subjects of
urban residence, younger age, having higher education, higher income and
practice binge drinking tend to be associated with the Transitional dietary pattern.
Meanwhile, a higher score for the Traditional pattern was related to subjects with
rural residence, intermediary education and physically active. After adjustment
for several confounding factors and total energy intake, the Transitional dietary
pattern was significantly associated with an increased risk of BMI (odds ratio of
the highest quintile vs lowest, 2.47; 95% confidence interval: 1.04–5.86; P for
trend <0.002). For the male adults, the Transitional dietary pattern was
significantly associated with an increased risk of central obesity and body fat
(OR: 4.08; 95% CI: 1.11–14.97; P for trend <0.034 and OR: 4.35; 95% CI: 1.21–
15.58; P for trend <0.024, respectively). As for the Traditional dietary pattern, the
higher score was associated with an increased risk of central obesity among the
women, after adjustment for confounders (OR: 4.59; 95% CI: 1.58–13.30; P for
trend <0.001, and after further adjustment for energy, intake OR: 3.74; 95% CI:
0.92–15.20; P for trend <0.065). On the other hand, the higher score for the
Traditional diet was related to a decreased risk of central obesity among the men
(Q3vsQ1. OR: 0.26; 95% CI: 0.08–0.79; p<0.018 and Q4vsQ1. OR: 0.29; 95%
CI: 0.09–0.95; p<0.041). Meanwhile, the Healthy dietary pattern was significantly
associated with a lower risk of BMI (OR: 0.49; 95% CI: 0.25–0.95; P for trend
<0.035). In conclusion, this study identified three major dietary patterns and their
associations independently with obesity risk among Mongolian adults. Diet,socio-demographic and lifestyle factors should be taken into consideration when
designing community-based obesity prevention interventions. The study findings
suggest that public health efforts in Mongolia should be targeted at population
subgroups in order to address prevailing specific aspects of the Transitional and
Traditional dietary patterns, which were found to be associated with increased risk
of cardiovascular disease. |
