Demographic and socio-economic correlates of knowledge of the ovulatory cycle among tribal women in India: Evidence from the nationally representative survey (NFHS-5).

BACKGROUND: The knowledge of ovulatory cycle (KOC) is the basis for natural family planning methods. The absence of knowledge is a notable issue since the ovulatory cycle plays a crucial role in reproductive health and empowers women to make informed decisions that influence their lives. This study examines the knowledge of the ovulatory cycle among reproductive tribal women in India and its demographic and socio-economic determinants.

METHODS: The data were derived from the National Family Health Survey conducted in 2019-2021. The effective sample size for the present study was 1,01,914 tribal women aged 15-49 years in India. Descriptive statistics along with bivariate analysis were conducted to find the preliminary results. Additionally, multivariable binary logistic regressions were conducted to determine the likelihood of KOC among tribal women across different characteristics. We conducted statistical analysis in STATA 17.0 (StataCorp) and used ArcGIS 10.8.2 for spatial mapping.

RESULTS: Out of 1,01,914 tribal women, 78.8 per cent lack correct knowledge of the ovulatory cycle. Notably, Education level significantly influences KOC, with secondary education showing higher odds of KOC (AOR: 1.24, 95% CI:1.006-1.528) compared to no education. Christian women exhibit lower odds of having KOC (AOR: 0.749, 95% CI:0.564-0.996) compared to Hindu women. Husband/partner's education level shows a strong association, with higher-educated partners correlating with higher odds of KOC (AOR: 2.501, 95% CI: 1.807-3.461) for higher education. Knowledge of any contraceptive method and current contraceptive use type are strongly associated with KOC. Additionally, rural residence negatively influences KOC (AOR: 1.545, 95% CI: 1.236-1.932), while exposure to mass media has a positive effect (AOR: 1.152, 95% CI: 0.975-1.362) albeit modest.

CONCLUSION: The study highlights the need for targeted educational and awareness programs to improve KOC among tribal women in India. By addressing factors such as education, religious influences, and place of residence, we can empower these women to make informed decisions about their reproductive health, ultimately enhancing their overall well-being and quality of life. This knowledge is not only a foundation for natural family planning but also a key driver of women's agency and autonomy in shaping their lives.
