title: Differentials in measures of dietary quality among adolescents in Jimma zone, Southwest Ethiopia.
abstract: BACKGROUND
  nutritionally adequate, safe and good quality diet is essential for human health, school performance, and employment output. Dietary diversity, consumption of animal source food and food variety score are commonly used measures of dietary quality. This study aimed to assess gender & sociodemographic differentials in measures of dietary quality among male and female adolescents.
  
  
  METHODS
  As part of the Jimma Family Longitudinal Study of Youth households with a youth between 13-17 years were randomly sampled from Jimma Town, the small towns and nearby rural Kebeles. Dietary diversity was assessed by asking youth about the consumption of 32 different food items included in the survey, which were regrouped into four major food groups. The four groups included animal source foods (10 items), fruits-vegetables (11 items), cereals (7 items) and legumes-nuts (2 items). From these food groups, measures of dietary diversity, food variety score, and animal source food consumption were calculated Logistic regression model was done using SPSS for windows version 12.0.1 to determine the odds ratios and predicted probabilities of consuming diversified diet.
  
  
  RESULTS
  Overall, 826 (39.7%), 819 (39.4%) and 955 (45.9%) of adolescents had low quality diet as measured by dietary diversity, consumption of animal source food and food variety score, respectively. Predictors of a diversi-fied diet consumption were male gender, (1.3 OR, 95% CI 1.1, 1, 5), living in small towns (1.7 OR (95% 1.3, 2.1) and being a member of household in the high-income quartile (2.1 OR 95% CI 1.5, 2.8). Intake of animal source foods was associated with the highest level of education achieved in the household (1.4 OR 95% CI: 1.1, 1.8), being male (1.3 OR 95% CI: 1.1, 1.5), being in a households with highest income quartile (2.3 OR 95% CI: 1.6, 3.1). Adolescents who lived in households with the highest income quartile and those who lived in the small towns were 1.6 and 1.4 times more likely to have high food variety score.
  
  
  CONCLUSIONS
  Large proportion of adolescents consumed low quality diets, which may effect on their education and work productivity and contribute to an intergenerational cycle of malnutrition. Interventions designed to improve dietary quality should target female adolescents, those in the poorest households, and households with low levels of education. Rural areas should also be targeted Thus targeted interventions to promote dietary quality and programmatic interventions to increases schooling may positively influence dietary quality in this area.
