Wealth-related inequalities in the utilisation of modern contraceptives in Papua New Guinea: evidence from the 2016–2018 Demographic and Health Survey data
Objective To examine the wealth-related disparities in modern contraceptives use among women in Papua New Guinea. Design We performed a cross-sectional analysis of the 2016–2018 Papua New Guinea Demographic and Health Survey data. We included 11 618 women of reproductive age in our final analysis. Percentages were used to present the results on utilisation of modern contraceptives. A concentration curve was used to summarise the cumulative use of modern contraceptives by wealth index (ranked into groups: richest, richer, middle, poorer and poorest). We used a decomposition analysis to estimate the contributions of individual factors towards wealth-related inequality in modern contraceptives use. We estimated the slope index of inequality (SII) and the relative index of inequality (RII) in modern contraceptive utilisation to provide summary evidence of inequality. Setting Papua New Guinea. Participants Women aged 15–49 years. Outcome measure Modern contraceptives utilisation. Results Ov
