BackgroundThe degree to which insecticide-treated net (ITN) supply accounts for age and gender disparities in ITN use among household members is unknown. This study explores the role of household ITN supply in the variation in ITN use among household members in sub-Saharan Africa.MethodsData was from Malaria Indicator Surveys or Demographic and Health Surveys collected between 2011 and 2016 from 29 countries in sub-Saharan Africa. The main outcome was ITN use the previous night. Other key variables included ITN supply (nets/household members), age and gender of household members. Analytical methods included logistic regressions and meta-regression.ResultsAcross countries, the median (range) of the percentage of households with enough ITNs was 30.7% (8.5–62.0%). Crude analysis showed a sinusoidal pattern in ITN use across age groups of household members, peaking at 0–4 years and again around 30–40 years and dipping among people between 5–14 and 50+ years. This sinusoidal pattern was more pronounced in households with not enough ITNs compared to those with enough ITNs. ITN use tended to be higher in females than males in households with not enough ITNs while use was comparable among females and males in households with enough ITNs. After adjusting for wealth quintile, residence and region, among households with not enough ITNs in all countries, the odds of ITN use were consistently higher among children under 5 years and non-pregnant women 15–49 years. Meta-regressions showed that across all countries, the mean adjusted odds ratio (aOR) of ITN use among children under 5 years, pregnant and non-pregnant women aged 15–49 years and people 50 years and above was significantly higher than among men aged 15–49 years. Among these household members, the relationship was attenuated when there were enough ITNs in the household (dropping 0.26–0.59 points) after adjusting for geographical zone, household ITN supply, population ITN access, and ITN use:access ratio. There was no significant difference in mean aOR of ITN use among school-aged children compared to men aged 15–49 years, regardless of household ITN supply.ConclusionsThis study demonstrated that having enough ITNs in the household increases level of use and decreases existing disparities between age and gender groups. ITN distribution via mass campaigns and continuous distribution channels should be enhanced as needed to ensure that households have enough ITNs for all members, including men and school-aged children.

Findings from this analysis have implications for promoting preconception care among U.S. men.

A proportion of women in couples use contraception without their partners' knowledge. There are two principal ways to measure this covert use in cross-sectional surveys like the Demographic and Health Surveys (DHS). First is a direct question, "Does your husband/partner know that you are using a method of family planning?" Second is an indirect method: the reports of both partners to the question on contraceptive use are matched, and if the woman reports a modern contraceptive method and the male partner reports nonuse, her use is considered covert. For 21 DHS surveys for which both estimates could be made, there are large discrepancies between the two. We found that a proxy variable-responses to the question, "Would you say that using contraception is mainly your decision, mainly your husband's/partner's decision, or did you both decide together?"-has high sensitivity and specificity for classifying those in the open category for both methods and those in the covert category for both methods. Recommendations are that the direct question be reinstated in the DHS and that the indirect method not be used by itself but in conjunction with the decision-making variable.

The need for engaging men aged 15 to 44 years in family planning education and care is substantial and largely unmet despite national public health priorities to include men in reducing unintended pregnancies.
