A randomized controlled trial of home visits by neighborhood mentor mothers to improve children's nutrition in South Africa

Malnourished children and babies with birth weights under 2500 g are at high risk for negative outcomes over their lifespans. Philani, a paraprofessional home visiting program, was developed to improve nutritional outcomes for young children in South Africa. One “mentor mother” was recruited from each of 37 neighborhoods in Cape Town, South Africa. Mentor mothers were trained to conduct home visits to weigh children under six years old and to support mothers to problem-solve life challenges, especially around nutrition. Households with underweight children were assigned randomly on a 2:1 ratio to the Philani program (n = 500) or to a standard care condition (n = 179); selection effects occurred and children in the intervention households weighed less at recruitment. Children were evaluated over a one-year period (n = 679 at recruitment and n = 638 with at least one follow-up; 94%). Longitudinal random effects models indicated that, over 12 months, the children in the intervention condition gained significantly more weight than children in the control condition. Mentor mothers who are positive peer deviants may be a viable strategy that is efficacious and can build community, and the use of mentor mothers for other problems in South Africa is discussed

Collecting maternal health information from HIV-positive pregnant women using mobile phone-assisted face-to-face interviews in southern Africa

Background: Most of the world's women living with human immunodeficiency virus (HIV) reside in sub-Saharan Africa. Although efforts to reduce mother-to-child transmission are underway, obtaining complete and accurate data from rural clinical sites to track progress presents a major challenge. Objective: To describe the acceptability and feasibility of mobile phones as a tool for clinic-based face-to-face data collection with pregnant women living with HIV in South Africa. Methods: As part of a larger clinic-based trial, 16 interviewers were trained to conduct mobile phone-assisted personal interviews (MPAPI). These interviewers (participant group 1) completed the same short questionnaire based on items from the Technology Acceptance Model at 3 different time points. Questions were asked before training, after training, and 3 months after deployment to clinic facilities. In addition, before the start of the primary intervention trial in which this substudy was undertaken, 12 mothers living with HIV (MLH) took part in a focus group discussion exploring the acceptability of MPAPI (participant group 2). Finally, a sample of MLH (n=512) enrolled in the primary trial were asked to assess their experience of being interviewed by MPAPI (participant group 3). Results: Acceptability of the method was found to be high among the 16 interviewers in group 1. Perceived usefulness was reported to be slightly higher than perceived ease of use across the 3 time points. After 3 months of field use, interviewer perceptions of both perceived ease of use and perceived usefulness were found to be higher than before training. The feasibility of conducting MPAPI interviews in this setting was found to be high. Network coverage was available in all clinics and hardware, software, cost, and secure transmission to the data center presented no significant challenges over the 21-month period. For the 12 MHL participants in group 2, anxiety about the multimedia capabilities of the hone was evident. Their concern centered on the possibility that their privacy may be invaded byi nterviewers using the mobile phone camera to photograph them. For participants in group 3, having the interviewer sit beside vs across from the interviewee during the MPAPI interview was received positively by 94.7% of MHL. Privacy (6.3%) and confidentiality (5.3%) concerns were low for group 3 MHL. Conclusions: Mobile phones were found both to be acceptable and feasible in the collection of maternal and child health data from women living with HIV in South Africa.

Diabetes Buddies: Peer Support Through a Mobile Phone Buddy System

Purpose: The purpose of this study is to test the feasibility and acceptability of a mobile phone-based peer support intervention among women in resource-poor settings to self-manage their diabetes. Secondary goals were to evaluate the intervention's effectiveness to motivate diabetes-related health choices. Methods: Women with diabetes (n = 22) in Cape Town, South Africa, participated in a 12-week program focused on providing and applying knowledge of health routines to manage diabetes. Women were linked with a buddy via a mobile phone for support and were questioned daily about a health behavior via text message. Women were assessed at recruitment and then 3 and 6 months later by a trained interviewer using a mobile phone for data collection. The women were evaluated on technology uptake, reduction of body mass index, blood glucose levels, and increases in positive coping and general health-seeking behaviors. Results: Women exchanged 16 739 text messages to buddies and received 3144 texts from the project. Women responded to 29% of texted questions (n = 1321/14 582). Women attended at least 9 of 12 possible intervention sessions; a third attended all 12 sessions (n = 8/22). Between baseline and 3 months, women increased their sleep and reported a higher level of positive action and social support coping, yet blood glucose increased by 3.3 points. From 3 to 6 months, spiritual hope decreased and diastolic blood pressure increased. One year later, the 22 women continue to attend meetings. Conclusions: Mobile phones are an easy and reliable way to provide peer support and disseminate health messages. Both positive and negative changes were observed in this pilot study. © 2012 The Author(s)

Qualitative interviews with mentor mothers living with HIV: potential impacts of role and coping strategies

In South Africa where HIV prevalence is high, mentor mother programmes have been used to promote the health and wellbeing of women enrolled in government programmes preventing vertical transmission. The Masihambisane Project trained mentors to be educators and facilitators as "expert patients" in self-help groups. While this and other similar interventions demonstrate positive outcomes for mothers and their children, the long-term repercussions for mentors delivering the intervention are seldom considered. This article explores the personal impact of being a mentor, the potentially traumatizing effects of repeatedly sharing their experiences of living with HIV and the coping strategies they adopt. Towards the end of the Masihambisane intervention, 10 semi-structured qualitative interviews were conducted with locally recruited mentors living with HIV and were thematically analysed. Mentors found the repeated telling of their stories a painful reminder of adverse personal experiences. In some cases, retelling caused a physical reaction. Mentors relied on coping strategies like taking breaks, writing their experiences down and debriefing sessions. Despite the difficulties associated with their role, some mentors found being advisors and the group sessions therapeutic and empowering. These findings indicate that the inclusion of peer mentors comes with certain responsibilities. While the mentors were resilient and some found the experience therapeutic and empowering found creative ways to cope with secondary trauma, the negative implications cannot be ignored. To effectively deliver a mentor-driven intervention to mothers enrolled in a programme to prevent vertical transmission, the possibilities of secondary trauma should be considered and mentors provided with ongoing counselling, training on coping skills and regular debriefing sessions.

A cluster randomized controlled trial evaluating the efficacy of peer mentors to support South African women living with HIV and their infants

Objective: We evaluate the effect of clinic-based support by HIV-positive Peer Mentors, in addition to standard clinic care, on maternal and infant well-being among Women Living with HIV (WLH) from pregnancy through the infant's first year of life. Methods: In a cluster randomized controlled trial in KwaZulu-Natal, South Africa, eight clinics were randomized for pregnant WLH to receive either: a Standard Care condition (SC; 4 clinics; n = 656 WLH); or an Enhanced Intervention (EI; 4 clinics; n = 544 WLH). WLH in the EI were invited to attend four antenatal and four postnatal meetings led by HIV-positive Peer Mentors, in addition to SC. WLH were recruited during pregnancy, and at least two post-birth assessment interviews were completed by 57% of WLH at 1.5, 6 or 12 months. EI's effect was ascertained on 19 measures of maternal and infant wellbeing using random effects regressions to control for clinic clustering. A binomial test for correlated outcomes evaluated EI's overall efficacy. Findings: WLH attended an average of 4.1 sessions (SD = 2.0); 13% did not attend any sessions. Significant overall benefits were found in EI compared to SC using the binomial test. Secondarily, over time, WLH in the EI reported significantly fewer depressive symptoms and fewer underweight infants than WLH in the SC condition. EI WLH were significantly more likely to use one feeding method for six months and exclusively breastfeed their infants for at least 6 months. Conclusions: WLH benefit by support from HIV-positive Peer Mentors, even though EI participation was partial, with incomplete follow-up rates from 6-12 months.
