简要总结
The project is the collaboration with the lead agencies National Institute of Public Health, World Vision and Emory University World Vision has a history of successfully implementing "Positive Deviance/Hearth (PDH)" programs across the globe. PDH is a community-based intervention utilizing locally appropriate health and infant feeding practices to rehabilitate underweight children and promote behavioral changes in caregivers. A recent systematic review on the PD/Hearth approach found that although some programs show clear success in particular settings, overall, the results were mixed for program effectiveness.
Furthermore, with the growing use of mobile phones and technology in the world, including Cambodia, there have been various studies and a systematic review that found SMS reminders and voice recordings to have promising impact on behavior change of patients for smoking cessation and improved adherence to drugs for asthma patients. Although there are positive findings around the use of mobile devices to improve behavior change, there has yet to be a study that examines the impact of mobile phones on improving behavior change of caregivers related to nutrition, water, sanitation and hygiene (WASH), health, and caring practices, which as a result, would decrease the prevalence of underweight in children 6-23 months of age.
This study will provide evidence on the effectiveness of the PDH model in Cambodia compared to the current standard of care. Investigators believe the PDH approach will be a powerful tool to reduce child malnutrition. In addition, given the intensity and cost burden associated with PDH, investigators will simultaneously test if the intensity of the PDH model can be reduced by introducing an innovative application of mHealth to replace 50% of face-to-face education sessions (5 days) and all follow up visits with mobile support calls. Collectively this research will provide critical data to inform program operations on the optimal and most effective method to reduce child underweight in Cambodia.
In Year 1, the purpose of this study is to assess the effectiveness of contextualized messages through PDH programs and a mobile technology (mHealth), to improve knowledge, behaviour change, and level of confidence of caregivers with underweight children aged 6-23 months in feeding, hygiene, health-seeking, and caring practices. In Year 2, the study's aim will be to assess the prevention of underweight in the siblings of the children included in the three programs outside of the 360 study subjects from Year 1.

结局指标
主要结局
Change in mean of weight (grams) over time
时间窗: Measured at Baseline (Month 0), Midline (Month 3), Endline (Month 12)
Weight, height/length and MUAC will be measured at Baseline (month 0), Month 3, and Month 12. The investigators will assess the change in mean of weight (grams) among the three arms between baseline (Month 0), midline (month 3), and endline (month 12).
Change in percentage of caregivers who have adopted proper child feeding, hygiene, health-seeking, and caring practices
时间窗: Measured at Baseline (Month 0), Midline (Month 3), Endline (Month 12)
The investigators will assess the behavioral change regarding the child feeding, hygiene, health-seeking and caring practices between Baseline (Month 0), Midline (Month 3), Endline (Month 12) through quantitative questionnaire. The questionnaire was established by the research team which consists of topic around child feeding, hygiene, caring, health-seeking practices.
Assess the percentage of siblings of enrolled children in each group with a weight for height z-score <-2
时间窗: Measured at Year 2 Endline
Assessment of the percentage of underweight younger siblings of the child who was admitted into the program will be assessed through rapid survey. Younger siblings of the enrolled children will be measured weight, height/length and MUAC at the Year 2 endline. The data such as weight, height/length, MUAC, gender, and date of birth are needed to calculate the prevalence of underweight children. These data will be entered into the software ENA2015 to compare the weight-for-age, MUAC, height-for-age, and weight-for-height data to the international WHO reference standards in order to identify the underweight status of the children. The investigators will assess the difference in prevalence of underweight children among the three arms.
Change in prevalence of underweight children over time
时间窗: Measured at Baseline (Month 0), Midline (Month 3), Endline (Month 12)
Weight, height/length and MUAC will be measured at Baseline (Month 0), Month 3, and Month 12. The data such as weight, height/length, MUAC, gender, and date of birth are needed to calculate the prevalence of underweight children. These data will be entered into the software ENA2015 to compare the weight-for-age, MUAC, height-for-age, and weight-for-height data to the international WHO reference standards in order to identify the underweight status of the children. The investigators will assess the difference in prevalence of underweight children among the three arms between baseline (Month 0), midline (month 3), and endline (month 12).
Change in percentage of caregivers self-reporting confidence in ability to adopt proper child feeding, hygiene, health-seeking, and caring practices over time
时间窗: Measured at Baseline (Month 0), Midline (Month 3), Endline (Month 12)
The investigators will assess the confident level in ability to adopt proper child feeding, hygiene, health-seeking, and caring practics between Baseline (Month 0), Midline (Month 3), Endline (Month 12) through quantitative questionnaire. The questionnaire was established by the research team which consists of topic around child feeding, hygiene, caring, health-seeking practices.
Change in percentage of caregivers correctly answering questions on child feeding, hygiene, health-seeking and caring practices over time
时间窗: Measured at Baseline (Month 0), Midline (Month 3), Endline (Month 12)
The investigators will assess the knowledge improvement regarding the child feeding, hygiene, health-seeking and caring practices between Baseline (Month 0), Midline (Month 3), Endline (Month 12) through quantitative questionnaire. The questionnaire was established by the research team which consists of topic around child feeding, hygiene, caring, health-seeking practices.
