Insights
Regular physical activity in young adults is linked to lower body fat, especially for those with small birth weight. Exercise offers a protective effect against metabolic risks associated with low birth parameters.
Area of Science:
- Human physiology
- Metabolic health
- Exercise science
Context:
- Low birth weight is a known risk factor for metabolic disorders later in life, including insulin resistance and type 2 diabetes.
- Regular physical activity is recognized as a key factor in mitigating these health risks.
Purpose:
- To investigate the relationship between physical activity levels, body composition, and birth weight in young adults.
- To determine if regular exercise can influence body composition in individuals with a history of small birth weight.
Summary:
- The study analyzed 156 young adults, categorizing them by physical activity frequency and birth weight (small birth weight [SBW] vs. normal birth weight [NBW]).
- Physically active participants (Group I) exhibited significantly lower body fat content compared to less active individuals (Group II), irrespective of birth weight.
- Young adults with SBW who were physically active showed higher fat-free mass than their inactive counterparts with SBW.
Impact:
- Regular physical activity plays a crucial role in managing body composition and potentially reducing metabolic disease risk in individuals with low birth weight.
- Findings highlight the protective influence of exercise, offering a strategy to counteract adverse health outcomes associated with small birth weight.
- This research underscores the importance of promoting physical activity among young adults, particularly those born with lower birth parameters.
Introduction:
Low birth parameters are associated with an increased risk of insulin resistance, type 2 diabetes, glucose intolerance and hypertension at later life. Regular physical activity can counteract these metabolic disorders.
The Aim Of The Study:
We determined the relation of the declared physical activity and body composition in young adults with respect to their birth weight.
Material:
A total of 156 subjects (52% women and 48% men) took part in the study (the average age 20.6±1.2 years). Participants who declared regular physical activity (minimum 3 times per week) were included in group I (n=66), others in group II (n=99). In each group, the percentage of people with small (SBW) and normal (NBW) birth weight was assessed.
Methods:
Information about birth parameters and duration of pregnancy was obtained from medical records. Infant's mass ≤2999 g was recognized as small birth weight. Body height, body weight, waist and hips circumferences and body composition by BIA were measured. Frequency of physical activity was determined during an interview.
Results:
Percentage of participants with small birth weight was respectively 17% in group I and 21% in group II. In group I standardized body height was significantly lower in subjects with SBW in comparison with those with NBW. Participants from group II with SBW had markedly lower standardized body weight and standardized BMI than adults with NBW. Independently of birth weight physically active persons characterized higher WHR values than their non active counterparts. Body fat content was significantly lower in group I (both in participants with SBW and NBW). Women and men from group I with SBW had also higher fat free mass in comparison with those from group II.
Conclusions:
Body fat content in young adults with small birth weight is related to their physical activity. People who regularly exercise had lower fat mass in comparison with non exercising ones. This is the confirmation of a protective influence of physical activity.
