30 7월 Pearsons’ relationship coefficient(r) is actually calculated to see the partnership anywhere between Bmi-BF% throughout the various other age range
A cross sectional investigation was conducted, where grownups out of 18–83 many years have been grouped to your young (18–39 years) middle-aged (40–59 years) and you will more mature (>60 years). BF% is estimated of bioelectrical impedance analysis. Several regression research is actually did to choose the effectation of years and you can intercourse regarding the dating and you may polynomial regression try carried out to see its' linearity. The fresh relationship ranging from many years-Bmi, age-BF % was basically separately assessed.
Efficiency
Out of 1114 participants, 49.1% were males. The study sample represented a wide range of BMI values (14.8-41.1 kg/m 2 ,Mean 23.8 ± 4.2 kg/m 2 ). A significant positive correlation was observed between BMI-BF%, in males (r =0.75, p < 0.01; SEE = 4.17) and in females (r = 0.82, p < 0.01; SEE = 3.54) of all ages. Effect of age and gender in the BMI-BF% relationship was significant (p < 0.001); with more effect from gender. Regression line found to be curvilinear in nature at higher BMI values where females (p < 0.000) having a better fit of the curve compared to males (p < 0.05). In both genders, with increase of age, BMI seemed to increase in curvilinear fashion, whereas BF% increased in a linear fashion.
Results
Body mass index highly correlate having BF % projected by bioelectrical impedance, within this sub people out of South Far-eastern people. This dating is actually curvilinear in the wild and you will was somewhat dependent on age and gender. Our very own findings contain the importance of getting age and sex within the so you're able to said when using Body mass index to expect surplus fat payment/being obese, inside the a populace.
Background
Over weight and you will carrying excess fat is defined as unpredictable or body fat buildup in your body which can affect fitness . Over the past couple many years, new prevalence away from obesity has increased and also be a significant around the world wellness risk [dos,3].
