Age at first exposure to violence and later mental health outcomes: A sex-disaggregated, multi-country analysis in sub-Saharan Africa.

BACKGROUND

A growing body of research has begun examining the relationship between a child's age at first exposure to violence and outcomes of mental wellbeing, though no studies have assessed these relationships in the sub-Saharan African (SSA) region.

OBJECTIVE

Given known gender and sex differences in violence exposure and mental health symptomology, this study conducts a multi-country, gender-stratified analysis of the relationship between age at first incident of physical violence and outcomes of wellbeing in SSA.

PARTICIPANTS AND

SETTING

This study uses data from the Violence Against Children Surveys on 13-24-year-old males and females in five SSA countries (Kenya (2010), Malawi (2013), Nigeria (2014), Tanzania (2009), and Uganda (2015)).

METHODS

The predictor of interest is a categorical variable indicating whether a respondent's first exposure to physical violence took place from 0 to 5, 6-11, 12 and older, or never. Outcomes of interest include: sadness, anxiety, suicide ideation, smoking, drug use, and alcohol use. Employing both country-specific and pooled data, gender-stratified, multiple logistic regressions are used to estimate the effect of age at first exposure to physical violence on the six outcomes of interest.

RESULTS

Findings show significant variation across countries in age at first exposure to physical violence. For females, findings reveal no association between age at first exposure and outcomes of wellbeing; all periods were equally associated with poor outcomes. For males, results show increased likelihood of anxiety, suicide ideation, and alcohol use when the first violence exposure occurred from 0 to 5 years.

CONCLUSIONS

This study advances the literature on gender and sex differences in mental health symptomology, suggesting that boys and girls may exhibit different symptomology in response to comparable exposures to violence.
