简要总结
Building on the success of community-based peer education and counselling in breastfeeding, it is possible to address young child feeding and health practices in the surveyed district. Opportunities that can optimise success and encourage behaviour change in the district include mothers willingness to modify some feeding options; support of family members; seasonal availability and accessibility of foods; established set-up of village peers and existence of health centres and health staff in some villages. This study has developed a feasible, context-specific nutrition education package for use in rural Tanzania. The package is composed of 4 components, namely 1) education and counselling of mothers, 2) training of community-based nutrition counsellors, 3) sensitisation meetings with health staff and family members, and 4) supervision of community-based nutrition counsellors. The intervention will use a parallel cluster-randomised controlled trial design where infants will be recruited when aged 6 months and followed up for 9 months. The intervention expects to provide information and, where appropriate, recommendations to strengthen the nutrition component in the health education programme of the Tanzania child health services.
The study hypothesises that the nutrition education package will be more effective than the routine health education in improving feeding practices, dietary adequacy and growth of infants and young children. Specific objectives of the study include:
- To evaluate the effectiveness of a nutrition education package on feeding practices and dietary adequacy
- To determine the effectiveness of a nutrition education package in improving growth and health of infants and young children
- To document the process of implementation of the nutrition education package to promote optimal feeding and health practice
详细描述
Design:
A parallel cluster randomised controlled trial will be conducted in rural central Tanzania in 9 intervention and 9 control villages. A simple randomisation with a 1:1 allocation using a list of random numbers generated in Microsoft Excel 2007 will be used to randomise villages to either control or intervention group. Generation of allocation sequence and randomisation of clusters will be done by a statistician blinded to study groups and not participating in the research.
Recruitment and collection of baseline information:
After cluster randomisation, sub-village leaders will identify all infants aged 6 months and their parents in a systematic door-to-door survey. Parents will be invited to a meeting where the nature and purpose of the trial and eligibility criteria will be explained. Thereafter, their infants will be screened for eligibility.
Parents and infants who meet the inclusion criteria, agree to participate in the trial and give a written informed consent will have their infants recruited. Baseline information of recruited infants and their parents (i.e. household's, parents' and infant's characteristics) will be collected using a structured questionnaire. Structured interviews with village and sub-village leaders will also be conducted to collect village information (i.e. population, health facility, water supply, schools, livelihoods, resources, economic opportunities).
