Key Social Norms Take-aways Gender norms—context-specific beliefs about appropriate behavior for different genders—shape health outcomes across the life course. This study highlights that non-conformity to gender norms often results in health harms, especially for girls and women. These norms intersect with religion, wealth, and geography, creating complex patterns of health inequity. Addressing gender norms is critical to designing effective, context-sensitive health interventions.

Objectives To examine how gender norms influence health outcomes globally by using innovative analyses of existing survey data, and to explore how proxy measures can be used to study gender norms in the absence of direct measurement.

Methods The study uses six case studies drawn from national and subnational survey datasets (e.g., DHS, Birth Cohorts, Add Health) to analyze gendered health pathways. Proxies for gender norms were constructed by aggregating behaviors and attitudes at community or school levels. Analytical methods included geospatial clustering, regression models, and interaction testing between gender norms and social factors like wealth and religion.

Intervention Details Not applicable—this is a multi-case research study using secondary data analysis.

Results

In Ethiopia, care-seeking for boys was prioritized over girls in Muslim-majority areas, highlighting son preference beyond economic explanations.
In South Africa and Brazil, adolescent perceptions of peer and parental judgments about body image influenced later eating disorders and mental health, particularly among girls.
In the U.S., adolescents who deviated from peer gender norms faced higher risks of depression, substance use, and risky behaviors.
In Zambia, discordance between adult attitudes and behaviors on premarital sex was linked to increased HIV risk for adolescent girls.
In Nigeria, women working outside the home experienced more intimate partner violence where female employment was non-normative.
Conclusions Gender norms profoundly affect health but are poorly captured in standard surveys. Proxy measures can reveal meaningful associations between norms and health outcomes. Normative environments shape individuals’ access to care, exposure to risk, and responses to health behaviors. To achieve gender equity in health, improved data collection and attention to the social enforcement of norms are essential.
