Abstract
MELLADO PENA, Fernanda; LEYTON DINAMARCA, Bárbara and KAIN BERKOVIC, Juliana. Evaluation of the Chilean program “Vida Sana 2017” in participants under 20 years of age after 6 months of intervention. Nutr. Hosp. [online]. 2020, vol.37, n.3, pp.559-567. Epub Nov 30, 2020. ISSN 1699-5198. https://dx.doi.org/10.20960/nh.02970.
Introduction:
the Chilean “Programa Vida Sana” (Healthy Life Program) (PVS) seeks to reduce risk factors for chronic diseases in overweight/obese subjects between 2 and 64 years of age.
Objective:
to evaluate in 2-20-year-old participants the results of the PVS applied in 2017 in relation to nutritional status and fitness after a 6-month intervention.
Methods:
an observational study analyzing secondary data. During 6 months the PVS included: medical, nutritional and psychological consultations (PC), laboratory exams, physical activity sessions (PAS), and healthy life workshops (HLW). Subjects were categorized into: 2-5, 6-10, and 11-19 years. We analyzed participation in activities; improvement of nutritional status [BMI-Z] and fitness [standing long-jump test (SLJ), 6-minute walk test (6MWT), 30-second chair stand (30-SCS)] according to initial NS using Student’s t-test for paired samples, and the contribution of the program´s activities to NS and fitness (logistic regression, Hosmer-Lemeshow test). The STATA 14.2 program was used, with p < 0.05, 95 % CI, being considered significant.
Results:
the sample included 13,611 (53 % girls). At 6 months about 50 % of participants improved their EN and CF. From 2 to 5 years, participation in ≥ 48 PAS, 2 PC and ≥ 3 HLW significantly increased the likelihood of improvement in NS and fitness. From 6 to 10 only HLW played a role, and from 11 to 19 only PAS in initially obese subjects.
Conclusions:
the activities of PVS-2017 contributed significantly to improved NS and fitness in subjects of 2-5 years of age; however, in 6-10- and 11-19-year-old participants its contribution was low. Only half of participants improved their NS and fitness during the 6 months of intervention.
