Objectives: The factors associated with quality of life (QOL) and anthropometric measurements as outcomes of food consumption were examined among school-age children in Tanzania.Methods: A cross-sectional study was undertaken in September 2013 in Tanzania. Anonymous self-administered questionnaire surveys were conducted in the Kiswahili language among primary school children in the fifth and/or sixth grade aged 10–14 years. The survey probed sociodemographic characteristics such as age, gender, living with family members, number of meals/snacks per day, food consumption in the previous 24 hours, and QOL, as well as anthropometric measurements (height and weight). The Rohrer index was calculated based on height and weight. After presenting the mean and standard deviation (SD) of height, weight, and the Rohrer index score by age and gender, the Rohrer index score was categorized into three groups (low weight, normal weight, and overweight) and analyzed according to sociodemographic characteristics and food consumption using the chi-square test. Furthermore, the QOL score was analyzed using the t test. Multivariate linear regression analysis was used to analyze the associations between the QOL score and sociodemographic characteristics and food consumption.Results: A total of 694 children (male: 312; female: 382) participated in this study. According to the Rohrer index, 273 (39.3%) children were classified as low weight, 353 (50.9%) were normal weight, and 68 (9.8%) were overweight. A total of 459 (66.1%) children reported having had three or more meals and/or snacks on the day before the study. In addition, 127 (18.3%) children had not eaten any protein-rich food on the day before the study, although almost all had eaten at least one carbohydrate-rich food per day. Regardless of region, location, gender, and age, living without parents was associated with short stature (P = 0.010). A high QOL score was associated with having three or more meals and/or snacks per day (P < 0.001).Conclusions: The security of physiological needs such as a guarantee of three meals per day could contribute to higher QOL among underserved children.
