To assess the prevalence of food insecurity and the independent association between depression and food insecurity among youth living in two urban settings in South Africa.
Baseline cross-sectional survey data was analysed from a prospective cohort study conducted between 2014 and 2016 among youth (aged 16-24 years) in Soweto and Durban. Interviewer-administered questionnaires collecting socio-demographic, sexual and reproductive health and mental health data were conducted. Household food insecurity was measured using the 3-item Household Hunger Scale, with food insecure participants defined as having 'moderate' or 'severe hunger' compared to 'no hunger'. Depression was assessed using the 10-item Center for Epidemiological Studies Depression (CES-D 10) Scale (range 0-30, probable depression ≥ 10). Multivariable logistic regression models were used to estimate the association between depression and food insecurity.
There were 422 participants. Median age was 19 years (interquartile range [IQR] 18-21) and 60% were women. Overall, 18% were food insecure and 42% had probable depression. After adjustment for socio-demographic variables (age, gender, female-headed household, household size and school enrolment), participants with probable depression had higher odds of being food insecure than non-depressed participants (2.79, 95%CI 1.57-4.94).
Nearly one-fifth of youth in this study were food insecure. Those with probable depression had increased odds of food insecurity. Interventions are needed to address food insecurity among urban youth in South Africa, combining nutritional support and better access to quality food with mental health support.
评估南非两个城市青年人群中粮食不安全的流行情况，以及抑郁与粮食不安全之间的独立关联。
本研究对 2014 年至 2016 年期间在索韦托和德班开展的一项前瞻性队列研究中的青年（16-24 岁）的基线横断面调查数据进行了分析。采用访谈者管理的问卷调查收集社会人口统计学、性和生殖健康以及心理健康数据。采用三项目家庭饥饿量表（HHGS）衡量家庭粮食不安全状况，与“无饥饿”相比，粮食不安全参与者被定义为“中度”或“重度饥饿”。抑郁采用 10 项流行病学研究中心抑郁量表（CES-D 10 量表）（范围 0-30，可能抑郁≥10）进行评估。采用多变量逻辑回归模型估计抑郁与粮食不安全之间的关联。
共纳入 422 名参与者。中位年龄为 19 岁（四分位距 [IQR] 18-21），60%为女性。总体而言，18%的参与者粮食不安全，42%的参与者可能患有抑郁。在校正社会人口统计学变量（年龄、性别、女性户主家庭、家庭规模和入学）后，可能患有抑郁的参与者粮食不安全的可能性是无抑郁参与者的 2.79 倍（95%CI 1.57-4.94）。
在这项研究中，近五分之一的青年存在粮食不安全问题。那些可能患有抑郁的人更有可能出现粮食不安全问题。需要采取干预措施，以解决南非城市青年的粮食不安全问题，将营养支持和更好地获得优质食物与心理健康支持相结合。
