Greater involvement of HIV-infected peer-mothers in provision of reproductive health services as “family planning champions” increases referrals and uptake of family planning among HIV-infected mothers

Table 2 Time-series analysis for weekly FP services utilization by HIV-infected mothers during the study

	Pre-Intervention				Intervention				Post Intervention
Indicator	Base level, β₀	p-value	Base trend, β₁	p-value	Change in level, β₂	p-value	Change in trend, β₃	p-value	Change in level, β₄	p-value	Change in trend, β₅	p-value
(i) Proportion (%) of FP usage among mothers attending PNC/PMTCT	64.2	<0.001	0.1	0.784	4.2	0.389	0.4	0.351	−5.4	0.01	−0.2	0.603
(ii) Proportion (%) of referrals among mothers not using and in need FP	74.7	<0.001	−3.0	0.005	48.7	<0.001	2.9	0.077	8.3	0.701	−1.5	0.375
(iii) Proportion(%) of FP uptake among mothers referred,not using and in need of FP	61.0	<0.001	−1.5	0.110	29.4	0.006	1.9	0.176	5.2	0.773	−1.9	0.338
(iv) Proportion(%) of FP refills among mothers receiving FP	45.2	<0.001	−1.7	0.002	11.9	0.020	1.5	0.010	9.2	0.015	0.1	0.860

Segmented regression of interrupted time-series models were fitted with an autoregressive term of one to measure the changes in levels and trends across the study phases. Positive coefficients represent increasing % whereas negative coefficients represent declining %. β ₀ is the proportion at the onset of the pre-intervention phase
β ₁ is the change in rate(trend) of the proportion during the pre-intervention phase. β ₂ is the change in proportion at the onset of the intervention phase. β ₃ is the change in rate(trend) of the proportion as compared to the rate (β ₁), in the pre-intervention phase. β ₄ is the change in proportion at the onset of the post-intervention phase. β ₅ is the change in rate(trend) of proportion as compared to the rate (β ₃) in the intervention phase. p- values correspond to the statistical significance level for the corresponding adjacent coefficient
