Nutritional status, feeding practice and incidence of infectious diseases among children aged 6 to 18 months in northern mountainous Vietnam
To assess the prevalence of undernutrition, incidence of infectious
diseases and the situation of feeding practices to determine the risk factors for undernutrition
among children aged 6 to 18 months in rural Vietnam. Design : A cross-sectional study
was conducted among one hundred eighty-eight mother-child pairs in Bac Giang, Vietnam.
Weight and height of the children were measured and referred to data from the
WHO/CDC/NCHS. Incidence of infectious diseases was diagnosed based on the WHO Recommended
Surveillance Standards. Data on socio-demographic variables and feeding
practices were obtained through a structured questionnaire. Result : The prevalence of
underweight, stunting and wasting was 19.7%, 23.4% and 5.3%, respectively. The incidence
of diarrhea and acute respiratory infections (ARIs) during the last 14 days of the interview
was 12.2% and 20.2%, respectively. Although 99% of the children were breastfed, the
prevalence of exclusive breastfeeding in the first 4 mo was 21.3%. Non-exclusive breastfeeding
in the first 4 month (OR 3.95, p=0.025) and low birth weight (OR 4.38, p=0.009)
were associated with underweight in the children, while incidence of infectious disease
was not (OR 1.16, p=0.734). Conclusion : Undernutrition is highly prevalent in the study
site and non-exclusive breast feeding is one of the risk factors
Development and validation of a food frequency questionnaire (FFQ) for assessing dietary macronutrients and calcium intake in Cambodian school-aged children
Abstract Background The nutritional status of school-aged children in Cambodia remains largely unknown. No tools for large-scale assessment of daily nutrient intake exist for this population, making development of appropriate intervention strategies difficult. Thus, we aimed to devise and validate a food frequency questionnaire (FFQ) that is suitable for and dedicated to assessing the dietary intake of macronutrients and calcium in school-aged children in Cambodia. Methods We developed an FFQ based on data from a single 24-h recall survey of 2020 children. The final list, which was developed as specified in the Block method and stepwise multiple regression analysis, comprised of 56 food items covering intake of energy, macronutrients, and calcium. We assessed the validity of the FFQ by comparison with a duplicated 24-h recall survey before and after de-attenuation. We also tested the reproducibility by comparing the first and second FFQs (FFQ1 and FFQ2) administered at an interval of approximately 6 weeks. Results The 56 food items in the FFQ accounted for 73.3% of the dietary calcium intake of Cambodian children and explained most of the inter-individual variation (cumulative R2: 0.96). The intake estimated by the FFQ was lower than the average intake across the two 24-h recall surveys. Spearman’s correlation coefficients for comparison between FFQ1 and FFQ2 ranged from 0.29 for fat to 0.47 for calcium. After de-attenuation of data, Pearson’s correlation coefficients ranged from 0.38 for fat to 0.71 for energy. Cross-classification analysis indicated that the average percentage of the subjects classified in the same or adjacent quartiles was 78.0%. Conclusions The FFQ is potentially a reliable scale for measuring nutrient intake in this population
