简要总结
Alive & Thrive (A&T) is an initiative that supports the scaling up of nutrition interventions to save lives, prevent illnesses, and contribute to healthy growth and development through improved maternal nutrition, breastfeeding and complementary feeding practices. In Ethiopia, A&T tested the feasibility of implementing a package of locally tailored adolescent nutrition interventions through school-based (flag assemblies, classroom lessons, girls' clubs, peer mentoring, weight and height measurement, and parent-teacher meetings) and community platforms (health post and home visits and community gatherings). The evaluation used a two-arm cluster-randomized, non-masked trial design, consisting of two cross-sectional surveys in 2019 and 2021.
详细描述
Adolescence is a critical period of physical and psychological development and for achieving human potential. Rapid physical, psychosocial and cognitive growth and development is coupled with increased energy and nutrient requirements (Das et al., 2017; Spear 2002). Poor nutrition during adolescence can have adverse consequences impacting health in adulthood. The significance of nutrition during adolescence is especially important for girls, as poor nutrition can affect their well-being as well as the survival, health and well-being of their children (Das et al. 2017).
A&T Ethiopia implemented a package of adolescent nutrition interventions through school-based (flag assemblies, classroom lessons, girls' clubs, peer mentoring, weight and height measurement, and parent-teacher meetings) and community platforms (health post and home visits and community gatherings). IFPRI tested the feasibility of the behavior-change interventions and examined their impacts on adolescent girls' diets, compared with standard school and community activities in control areas.
The evaluation used a two-arm cluster-randomized, non-masked trial design, consisting of two cross-sectional surveys of in-school adolescent girls aged 10-14 years enrolled in grades 4-8. The unit of randomization is the primary school which includes grades 1-8. The baseline survey was conducted in October-November 2019 (at the beginning of the school year), and the endline survey took place in March-April 2021 (following the end of first semester classes). In 2020, after 3 months of program implementation, program activities were halted from March to October (over 6 months) due to the COVID-19 pandemic, thus the endline survey was postponed to the following school year after implementation was reinitiated.
The overall study objective was to determine the feasibility of delivering adolescent nutrition interventions primarily through school-based platforms and their impact on the diet of adolescent girls.
