Despite the high prevalence of adolescent food insecurity in Ethiopia, there is no study which documented its association with suboptimal dietary practices. The objective of this study is to determine the association between adolescent food insecurity and dietary practices. We used data on 2084 adolescents in the age group of 13-17 years involved in the first round survey of the five year longitudinal family study in Southwest Ethiopia. Adolescents were selected using residence stratified random sampling methods. Food insecurity was measured using scales validated in developing countries. Dietary practices were measured using dietary diversity score, food variety score and frequency of consuming animal source food. Multivariable regression models were used to compare dietary behaviors by food security status after controlling for socio-demographic and economic covariates. Food insecure adolescents had low dietary diversity score (P<0.001), low mean food variety score (P<0.001) and low frequency of consuming animal source foods (P<0.001). After adjusting for other variables in a multivariable logistic regression model, adolescent food insecurity (P<0.001) and rural residence (P<0.001) were negatively associated with the likelihood of having a diversified diet (P<0.001) and frequency of consuming animal source foods, while a high household income tertile was positively associated. Similarly, multivariable linear regression model showed that adolescent food insecurity was negatively associated with food variety score, while residence in semi-urban areas (P<0.001), in urban areas (P<0.001) and high household income tertile (P = 0.013) were positively associated. Girls were less likely to have diversified diet (P = 0.001) compared with boys. Our findings suggest that food insecurity has negative consequence on optimal dietary intake of adolescents. Food security interventions should look into ways of targeting adolescents to mitigate these dietary consequences and provide alternative strategies to improve dietary quality of adolescents in Southwest Ethiopia.
尽管埃塞俄比亚青少年食物不安全现象普遍存在,但目前尚无研究记录其与饮食不佳之间的关联。本研究旨在确定青少年食物不安全与饮食行为之间的关联。我们使用了在埃塞俄比亚西南部进行的为期五年的家庭纵向研究第一轮调查中涉及的 2084 名年龄在 13-17 岁的青少年的数据。采用居住分层随机抽样方法选择青少年。使用在发展中国家得到验证的量表来衡量食物不安全。使用饮食多样性评分、食物种类评分和食用动物源食品的频率来衡量饮食行为。在控制社会人口学和经济协变量后,使用多变量回归模型比较食物安全状况下的饮食行为。食物不安全的青少年饮食多样性评分较低(P<0.001)、平均食物种类评分较低(P<0.001)和食用动物源食品的频率较低(P<0.001)。在多变量逻辑回归模型中调整其他变量后,青少年食物不安全(P<0.001)和农村居住(P<0.001)与饮食多样化(P<0.001)和食用动物源食品的频率呈负相关,而高家庭收入 tertile 呈正相关。同样,多变量线性回归模型显示,青少年食物不安全与食物种类评分呈负相关,而半城市地区(P<0.001)、城市地区(P<0.001)和高家庭收入 tertile(P = 0.013)与食物种类评分呈正相关。与男孩相比,女孩不太可能饮食多样化(P = 0.001)。我们的研究结果表明,食物不安全对青少年最佳饮食摄入有负面影响。粮食安全干预措施应着眼于针对青少年的方法,以减轻这些饮食后果,并为改善埃塞俄比亚西南部青少年的饮食质量提供替代策略。
