Abstract

Purpose

Childhood obesity is one of the major concerns in the last years due to the association with future health problems and all-cause mortality. However, there is a subset of adolescents with overweight/obesity who present a metabolic healthy profile. Therefore, the aim of this study was to examine the prevalence of metabolically healthy but overweight/obese adolescents and whether sedentary time, physical activity, and fitness differ between metabolically healthy and nonmetabolically healthy phenotypes.

Methods

A subsample of 237 European adolescents from the HEalthy Lifestyle in Europe by Nutrition in Adolescence study (n = 3,528, participation rate: 61.3%) with overweight/obesity were included. The study sample was not fully representative for the European adolescent population. Based on sex- and age-specific metabolic syndrome cutoff points for triglycerides, glucose, blood pressure, and high-density cholesterol participants were classified as metabolically healthy or nonmetabolically healthy. Sedentary time, physical activity, and fitness were assessed by accelerometry and the Alpha battery, respectively.

Results

The prevalence of metabolically healthy status in adolescents with overweight and obesity was higher in girls (87%) than in boys (74%, p = .019), being similar when only obesity was considered. Sedentary time was lower in metabolically healthy overweight/obese than in nonmetabolically healthy participants (mean difference = 48.0 minutes, p = .012). Moderate and moderate-to-vigorous physical activity were higher (p's < .05) in metabolically healthy than in nonmetabolically healthy adolescents with overweight/obesity (mean difference = 7.9 min/day and 10.9 min/day, respectively). No significant differences were found in fitness. Overall, these results persisted when only adolescents with obesity were included in the analyses.

Conclusions

Metabolically healthy adolescents with overweight/obesity are less sedentary and more active than their nonmetabolically healthy peers with overweight/obesity, yet consistent differences in fitness were not observed.

Study design

The present study is under the framework of the HEalthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study (HELENA-CSS; www.helenastudy.com). The HELENA study was performed from 2006 to 2008 in 10 European cities. A total of 3,528 European adolescents aged 12.5–17.5 years participated in the study (participation rate: 61.3%) [10]. Details of recruitment, standardization, and harmonization processes were published elsewhere [11]. Blood samples were collected in one third of

Characteristics of the study sample and prevalence of MHO

Age, anthropometry, prevalence of MHO/non-MHO, FAS, maternal educational level, and puberty stage are shown in Table 1. Briefly, non-MHO adolescents had higher weight, height, and body mass index than MHO (all p ≤ .006). Prevalence of MHO and non-MHO in European adolescents from the HELENA study is shown in Figure 1. Overall, the prevalence of MHO was 80% (n = 190) and 70% (n = 166) for overweight/obese and obese groups, respectively. The prevalence of MHO was roughly 13%–19% higher in girls

Discussion

The main findings of this study show that (1) prevalence of MHO was 80% for overweight/obese and 70% for obese, being higher in girls than in boys; (2) after adjusting for potential covariates and using objective measures, sedentary time was higher in non-MHO adolescents with overweight/obesity than in their MHO peers; (3) MPA and MVPA were higher in MHO than in non-MHO, both in the group with overweight/obesity and only obesity; and (4) no consistent differences were found in health-related

      Citation Excerpt :

      The participants with at least one component of the syndrome were considered as metabolically unhealthy. This definition, which is considered to be stricter, was based on a literature review and opinions of specialists, and it has been largely used to classify participants in recent studies on metabolic health [20,27,28]. Based on this proposal, the individuals of this study were considered as metabolically healthy if they did not fall into any of these situations: triglycerides ≥150 mg/dL or using drugs to reduce triglycerides; HDL-c <40 mg/dL for men and <50 mg/dL for women, or using drugs to increase HDL-c; systolic blood pressure ≥130 mmHg and diastolic blood pressure ≥85 mmHg, or using antihypertensive drugs, and fasting glucose ≥100 mg/dL or using hypoglycemic drugs.
