“…Boys had a higher HGS compared with girls, which was most evident beginning at 14y. These values are, on average, higher than those reported in studies previously conducted among Chilean children and adolescents [33]. For example, for adolescents aged 10-11, we found average HGS of 17.9 and 17.5 for boys and girls, respectively; while Garcia-Hermoso et al [33] (n = 2,026) reported 15.8 and 15.0 and Gomez-Campos et al [34] (n = 4,604) reported 15.0 and 14.9, respectively.…”

These differences may be due to socioeconomic level, as both of these samples were drawn exclusively from public schools, which tends to reflect a lower socioeconomic level, while the current sample contained adolescents from both public and private schools.…”

Relative handgrip strength, nutritional status and abdominal obesity in Chilean adolescents

Handgrip strength (HGS) is a well-established indicator of muscle strength and can help to identify risk of sarcopenic obesity in children. This study explores the relationship between adiposity and muscular strength in healthy Chilean adolescents. Adolescents (n = 491) aged 10-17 were selected from five schools in Santiago, Chile. HGS was determined by dynamometry. Anthropometry (weight, height, waist and mid arm circumference), physical activity and socioeconomic status were also measured. Relative HGS (RHGS) was calculated by dividing maximum HGS of the dominant hand by body-mass index (BMI) and low RHGS was categorized as <25 th percentile by sex. Logistic regression was used to determine the relationship between two markers of adiposity (abdominal obesity category by waist circumference and nutritional status measured by BMI category) and low RHGS, adjusting for possible confounding variables. Participants were on average 13.6y (2.4), 32.8% were overweight or obese and 37.5% were at risk of or had abdominal obesity. RHGS was 1.25 kg/kg/m 2 overall, with a significant difference by sex (1.51 for boys versus 1.14 for girls). In adjusted analyses, boys and girls with risk of abdominal obesity, had 3.3 (1.6-6.6) and 4.1 (1.8-9.3) increased odds of low RHGS, respectively, compared to boys and girls with normal waist circumference. Those with abdominal obesity compared to normal WC, had 8.5 (3.4-21.4) and 6.5 (2.0-21.3) increased odds of low RHGS for boys and girls, respectively. We observed similar associations for BMI category. In our sample of healthy adolescents, higher adiposity related to greater odds of low muscle strength measured by dynamometry. Considering the demographic shift from a young to an aging population in many countries, along with the increasing prevalence of obesity beginning in childhood, understanding how adiposity relates to low muscle strength is of growing importance.

Relative handgrip strength, nutritional status and abdominal obesity in Chilean adolescents

“…This is consistent with previous results that showed a positive correlation between BMI and handgrip strength in young Brazilian adults [36]. Moreover, high levels of muscular strength have been related to a more active lifestyle in Chilean children [37]. However, due to their higher weight, participants from rural areas might have more difficulties to move their body and this could be the reason for a lower level of muscle power, coordination capacity and speed in comparison to those from urban areas.…”

“…An additional advantage of the study was the use of a food photo album and nutritional software created specifically for Mexican population and the use of accelerometry to measure ST and PA. Most studies carried out in Mexico evaluate these variables through questionnaires of PA [9,33,37,47,53]. As a limitation, the limited availability in time and quantity of accelerometers decreased the sample of this variable.…”

Mexico shows a high prevalence of obesity in children and adolescents. Geographical location and cultural environment could play a role in the promotion of healthy lifestyles in terms of physical activity (PA), sedentary behavior (SB) and nutrition. The purpose of this study was to assess rural and urban differences in body composition (BC), physical fitness (PF), PA and nutritional status of adolescents from the state of Jalisco (Mexico). The study involved 469 students aged 13-17 years (55.0% girls) from 8 high schools. BC was analyzed by bioimpedance, and PF by standardized field tests. Objective measurements of PA and SB were taken in a subsample (n=240). Energy intake (EI) was calculated from two 24h recalls. Rural residents presented a higher prevalence of overweight, waist circumference, trunk fat mass, regional fat free mass and muscle handgrip strength (all p&lt;0.05, ηp2&lt;0.06). Cardiorespiratory fitness was similar among participants, whereas urban adolescents showed higher muscle power, speed-agility and flexibility scores (all p&lt;0.05, ηp2&lt;0.07). Overall lifestyle behavior in urban adolescents was more sedentary (p&lt;0.05, ηp2= 0.11). EI was similar in both locations. In conclusion, urban Mexican adolescents presented a generally higher sedentary behavior and better fitness and fatness profile than their rural peers.

“…(2) the percentage of adolescents achieving a satisfactory level of cardiorespiratory fitness (ie, >20 percentile) was 62.3% and 58.1% in boys and girls, respectively; (3) lack of regular assessment of fitness in children and adolescents at the national level 28 ; and (4) lack of national data on fitness levels in children (ie, 5-12 y old). However, a regional study that reported handgrip strength in 2026 children aged 8-12 years (nonrepresentative) showed that Chilean children scored higher than their South American counterparts from Colombia and Peru, but showed lower handgrip strength than European and Australian children.…”

Background: The study summarizes the findings of the 2018 Chilean Report Card (RC) on Physical Activity (PA) for Children and Adolescents and compares the results with the first Chilean RC and with other countries from the Global Matrix 3.0. Methods: A Research Work Group using a standardized methodology from the Global Matrix 3.0 awarded grades for 13 PA-related indicators based on the percentage of compliance for defined benchmarks. Different public data sets, government reports, and papers informed the indicators. Results: The grades assigned were for (1) “behaviors that contribute to overall PA levels”: overall PA, D−; organized sport participation, D−; active play, INC; and active transportation, F; (2) “factors associated with cardiometabolic risk”: sedentary behavior, C−; overweight and obesity, F; fitness, D; sleep, INC; and (3) “factors that influence PA”: family and peers, F; school, D; inclusion, INC; community and built environment, B; government strategies and investments, B−. Conclusions: Chile’s grades remained low compared with the first RC. On the positive side, Chile is advancing in environmental and policy aspects. Our findings indicate that the implementation of new strategies should be developed through collaboration between different sectors to maximize effective investments for increasing PA and decreasing sedentary time among children and adolescents in Chile.
