abstract: 'Background To address gaps in coverage and quality of nutrition services, Alive \& Thrive (A\&T) strengthened the delivery of maternal nutrition interventions through government antenatal care (ANC) services in Uttar Pradesh, India. The impact evaluation of the A\&T interventions compared intensive ANC (I-ANC) with standard ANC (S-ANC) areas and found modest impacts on micronutrient supplementation, dietary diversity, and weight-gain monitoring. Objectives This study examined intervention-specific program impact pathways (PIPs) and identified reasons for limited impacts of the A\&T maternal nutrition intervention package. Methods We used mixed methods: frontline worker (FLW) surveys (n = similar to 500), counseling observations (n = 407), and qualitative in-depth interviews with FLWs, supervisors, and block-level staff (n = 59). We assessed 7 PIP domains: training and materials, knowledge, supportive supervision, supply chains, data use, service delivery, and counseling. Results Exposure to training improved in both I-ANC and S-ANC areas with more job aids used in I-ANC compared with S-ANC (90\% compared with 70\%), but gaps remained for training content and refresher trainings. FLWs'' knowledge improvement was higher in I-ANC than S-ANC (22-36 percentage points), but knowledge of micronutrient supplement benefits and recommended foods was insufficient (<50\%). Most FLWs received supervision (>90\%), but supportive supervision was limited by staff vacancies and competing work priorities. Supplies of iron-folic acid and calcium supplements were low in both areas (30-50\% stock-outs). Use of monitoring data during review meetings was higher in I-ANC than S-ANC (52\% compared with 36\%) but was constrained by time, understanding, and data quality. Service provision improved in both I-ANC and S-ANC areas, but counseling on supplement benefits and weight-gain monitoring was low (30-40\%). Conclusions Systems-strengthening efforts improved maternal nutrition interventions in ANC, but gaps remained. Taking an intervention-specific perspective to the PIP analysis in this package of services was critical to understand how common and specific barriers influenced overall program impact.' affiliation: 'Nguyen, PH (Corresponding Author), Int Food Policy Res Inst IFPRI, Washington, DC 20005 USA.
