The relationship between social determinants of health and girls' age at menarche based on the world health organization model: path analysis

Objectives: Given the descending trend of menarche age and the effect of social determinants of health on menarche, the present study was conducted to examine the relationship model of social determinants of health with menarche age of girls.Materials and methods: The present cross-sectional study enrolled 840 mothers and their 6-17 year-old daughters in the city of Kashan, Iran (2020).

The statistical analysis was performed in SPSS-16, and the relationship model was examined using path analysis method in LISREL-8.8.Results: The girls' menarche age was directly affected by sister's (b = 0.83) and mother's menarche age (b = 0.05), BMI (b = 0.01), physical activity (b = -0.06), conversation orientation (b = -0.002), socioeconomic status (b = -0.01) and maternal general health (b = 0.009). It was also indirectly affected by mother's menarche age, social support, socioeconomic status, and maternal spiritual health and parents relationships.Conclusions: The results showed that the numerous factors affect the girls' age at menarche directly and indirectly.
