Abstract
ABSTRACT
Background
The prevalence of obesity is increasing in many Asian countries. However, longitudinal data on the impacts of dietary factors on weight gain in Asian populations are sparse.
Objectives
We evaluated the relationship between changes in intakes of nutrients, foods, and beverages and diet quality and long-term changes in body weight.
Methods
We used data (n = 3064) from the Singapore Multi-Ethnic Cohort, a prospective cohort including Chinese, Indian, and Malay residents aged 21–65 years. Dietary intakes were assessed using an FFQ, and body weight and waist circumference were measured during health examinations. Diet quality was evaluated using the Dietary Approaches to Stop Hypertension (DASH) and Alternative Healthy Eating Index (AHEI-2010) scores. Data were collected at baseline (2004–2010) and follow-up (2011–2016), with a mean follow-up of 6.0 years. Linear regression was used to assess the associations between dietary changes and weight change, adjusted for socio-demographic and lifestyle variables.
Results
Improvements in dietary quality scores (DASH, −0.34 kg per 5 points; AHEI-2010, −0.35 kg per 10 points) and replacement of carbohydrates with protein (−0.44 kg per 5% of energy) were significantly associated with less weight gain. Increased intakes of white rice (+0.25 kg per serving/d), soft drinks (+0.69 kg), red meat (+0.58 kg), and poultry with skin (+0.74 kg) were directly associated with weight gain. The replacement of 1 serving per day of white rice with whole grains (−0.68 kg), vegetables (−0.33 kg), poultry without skin (−0.79 kg), and eggs (−0.87 kg) was associated with less weight gain. Similar associations were observed between changes in dietary factors and changes in waist circumference.
Conclusions
Among Asian adults, increasing dietary quality, reducing soft drink consumption, and replacing white rice with whole grains, vegetables, and selected high-protein foods was associated with less weight gain.
