Rowlands IJ, Mishra GD & Lucke JC Association between young women’s physical and mental health and their method of contraception in a longitudinal, population-based study. BMJ Sexual & Reproductive Health, 2020; :

Background: Women's physical and mental health are strongly inter-related and may influence patterns of contraceptive use. We examined the longitudinal associations between young women's physical and mental health and method of contraceptive use over a 5-year period.Methods: Data from 4952 young women (=27 years) participating in the Australian Longitudinal Study on Women's Health who completed four self-reported surveys between 2013 and 2017 were analysed. Women's contraceptive use was categorised as: contraceptive pill/oral contraceptives, long-acting reversible contraception (LARC), condom, other methods and none. Multinomial logistic regression was used to determine the longitudinal associations between women's physical and mental health and method of contraception.Results: Over the 5-year period the percentage of pill users decreased from 60% (95% CI 58% to 61%) to 41% (95% CI 39% to 42%) and LARC users increased from 13% (95% CI 12% to 14%) to 21% (95% CI 20% to 22%) as did non-users from 9% (95% CI 8% to 9%) to 17% (95% CI 16% to 18%). Compared with women using the pill, women who used LARCs were more likely to be overweight (OR 1.34; 95% CI 1.17 to 1.53) and obese (OR 1.84; 95% CI 1.55 to 2.19), current smokers (OR 1.45; 95% CI 1.23 to 1.71) and reported fair or poor general health (OR 1.50; 95% CI 1.28 to 1.76) and very high levels of psychological distress (OR 1.47; 95% CI 1.24 to 1.76). Similar results were also found among women who used condoms or no contraception.Conclusions: Findings suggest that obesity, smoking and poor physical and mental health play an important role in young women's contraceptive use.
