Abstract
The aims of the study were to examine the moderating role of physical activity in
the relationship between cardiometabolic risk factors and adiponectin
concentration in adolescents. This is a cross-sectional study conducted with 96
adolescents of both sexes, between 11 and 17 years old. Body mass, height, fat
mass (FM), fat-free mass, systolic blood pressure, diastolic blood pressure,
high density lipoprotein, low density lipoprotein (LDL-c), triglycerides,
insulin, adiponectin, C-reactive protein, and level of physical activity (energy
expenditure questionnaire) were measured. Body mass index (BMI), triponderal
mass index (TMI), homeostasis model to assessment insulin resistance (HOMA-IR),
and quantitative insulin sensitivity check index (QUICKI) were calculated.
Macro-PROCESS for SPSS was used for moderation analyses. Direct interactions
were found for BMI, TMI, FM, insulin, and HOMA-IR and inverse for LDL-c, and
QUICKI. Protection against cardiometabolic risk was found when the PA-coeff was
completed above 1.57 coeff (BMI), 1.62 coeff (TMI), 1.55 coeff (FM), 1.41 coeff
(LDL-c)1.60 coeff (insulin), 1.59 coeff (HOMA-IR) and 1.35 coeff (QUICKI). We
conclude that physical activity was a moderator in the relationship with
adiposity, insulin resistance and sensitivity, LDL-c, and adiponectin. In this
context, we evidenced a relevant clinical impact on the health of adolescents,
demonstrating the interaction between anthropometrics variables and physical
activity.
