A waist size of 94 cm or more is a reliable indicator of high heart disease risk in people with spinal cord injuries, correctly identifying all cases but sometimes flagging healthy individuals.
Quantitative
Waist size and waist-to-height ratio are linked to five key heart disease risk factors and overall heart disease risk in people with spinal cord injuries.
Correlational
BMI, waist size, and waist-to-height ratio all relate to how much fat is stored around the belly in people with spinal cord injuries.
Standard BMI measurements don't accurately show how much body fat people with spinal cord injuries have, often making them seem less obese than they really are.
Descriptive
Living a sedentary lifestyle with Western habits leads to more people being obese even if they have a normal weight.
Causal
Doctors need to study why some women with normal weight have uneven fat distribution in their bodies, as it might affect their health.
Looking at fat in the trunk and legs compared to overall body fat is important for understanding body composition, even more than just knowing gender differences.
Total body fat, gender, and age account for most of the differences in leg fat among people.
Women with a healthy weight and normal overall body fat have more fat in their legs relative to their total body fat and trunk fat compared to obese people, but men with healthy weight don't show this pattern.
Using both waist size and handgrip strength together predicts metabolic syndrome better than using either one alone.
Adults with the smallest handgrip strength and largest waist size had over 4 times higher risk of metabolic syndrome issues in women and over 8 times in men compared to those with strongest grip and smallest waist.
People with weaker handgrip strength relative to their body weight tend to have worse metabolic syndrome scores.
Having a larger waist circumference is the main indicator of metabolic syndrome risk in adults from middle-income countries.
About 42% of the 5,000 adults studied in a middle-income country had metabolic syndrome, with 64% being women and an average age of 51.
A rare gene mutation in women (rs150090666) caused higher body fat but also better cholesterol levels (higher HDL, lower TG).
25 gene variants across 4 locations had different effects on body fat in men versus women.
The genes discovered explained about 3.35% of body fat differences in men and 2.60% in women.
While body fat percentage was genetically linked to heart disease and diabetes risk, the data didn't support that body fat directly causes these conditions.
Using genetic data, researchers found no evidence that body fat percentage directly causes diabetes, heart disease, or changes in cholesterol/triglycerides in men or women.
A specific gene variant (rs998584) linked to higher body fat in men also led to more fat in the hips/thighs, less belly fat, and lower risk of diabetes and heart disease.
In women, most genes linked to body fat (75%) didn't affect cholesterol, triglycerides, diabetes, or heart disease risk.
In men, most genes linked to body fat (68%) didn't affect cholesterol, triglycerides, diabetes, or heart disease risk.
Researchers discovered 7 new genes related to body fat in men and 10 new ones in women that weren't known before to affect body fat or related health issues.
Scientists found different sets of genes related to body fat in men and women; men have 195 genes linked to body fat, women have 174, and only 38 genes are common to both groups.
