Association of malnutrition and main-meal- and snack-predominant intake among female adolescent students in boarding schools in Tasikmalaya, Indonesia.

Background: Balanced dietary intake is needed to prevent malnutrition which is one of the nutritional problems faced by adolescents. Aim: To study the association between predominant dietary intake and nutritional status of female adolescent students in boarding schools in Tasikmalaya, Indonesia. Method: This cross-sectional study was conducted on 323 female adolescent students residing full-time in eight boarding schools in Tasikmalaya, West Java. Students' dietary intake was measured using the 3-non-consecutive-day 24-h recall method. The association between the predominant dietary intake and nutritional status was evaluated using binary logistic regression. Results: Of the 323 students, 59 (18.3%) were overweight/obese (OW/OB) and 102 (31.6%) had stunted growth. The predominant dietary intake in the OW/OB group was snacks, whereas, in the stunted group, it was main meals. Snack-predominant dietary intake was a risk factor for overweight and obesity (p = 0.008; adjusted odds ratio [AOR]: 2.276; 95% confidence interval [CI]: 1.244-4.164), but it was a protective factor against stunting (p = 0.008; AOR: 0.521; 95% CI: 0.322-0.842). Conclusion: The predominance of main meals and snacks as components of total dietary intake affected the nutritional status of female adolescent students living in boarding schools. Therefore, the dietary intake interventions should tailor and design the nutritional contents of main meals and snacks according to the nutritional status of the targeted individuals.
