Racial Disparities in Cardiovascular Risk Associated with Body Mass Index in Men and Women: A Subject-level Meta-analysis
Methods. This study uses Black Pooling Project data which includes subject level data on 27,691 men and women and 450,962 person-years of follow-up.
About this book
Results. As a group, blacks have a higher adjusted mean systolic blood pressure than whites and are classified as hypertensive at all BMI categories whereas in whites blood pressure did not reach the hypertensive range until a BMI of at least 31 kg/m2. The age-adjusted rise in blood pressure for a BMI increase of 25--30 kg/m2, is greater for white than black women (5.9+/-0.2 vs. 4.4+/-0.5 p=0.005) and for white than black men (6.0+/-0.3 vs. 4.3+/-0.7 p=0.03). The adjusted, relative risks for CHD, stroke and CVD mortality is significant for obesity in whites but not in blacks. In obese whites, the relative risk for CVD mortality is (1.59[1.20--2.09]) in women 60 years and (1.21[1.04--1.41]) in women 60 years. There are no such significant associations for black women.
To address our study aims we analyzed data from a community study of 229 fertile men 18 to 40 years of age. A standardized telephone interview was used to collect data on lifestyle exposures and potential confounders.
About this book
Our results did not reveal significant decrements in sperm outcomes associated with smoking status (current, former, never) or BMI, after confounder adjustment. Unexpectedly, former smokers had significantly lower proportions of immature sperm cells compared to non-smokers (-2.8%; 95% Confidence Limits (CL): -4.7%, -0.9%), and obese men (BMI ≥ 30) exhibited significantly higher sperm concentrations than men of normal weight (BMI 18.5-24.9) (16.2%; 95% CL: 2.0%, 32.3%). Sperm outcomes were generally more favorable among alcohol drinkers than non-drinkers. Conversely, men whose daily caffeine intake exceeded 300 milligrams had significantly lower proportions of morphologically normal sperm cells compared with non-caffeine drinkers (2.8%; 95% CL: -4.9%, -0.6%). Results suggest that lifestyle exposures and BMI vary considerably with respect to their independent effects on clinically-relevant markers of testicular function and germ cell DNA integrity among fertile men.

About this book
The Federal guidelines on the identification, evaluation, and treatment of overweight and obesity in adults have defined 'overweight' as a body mass index value between 25 and 29.9; and 'obesity' as a body mass index value greater than or equal to 30. BMI is a ratio between weight and height. It is a mathematical formula that correlates with body fat, used to evaluate if a person is at an unhealthy weight (given a certain height). BMI value is more useful for predicting health risks than the weight alone (for adults ages 18 and up). Individuals with high BMI's are at increased risk of developing certain diseases, including: Hypertension, Cardiovascular Disease, Dyslipidemia, Adult-Onset Diabetes (Type II), Sleep Apnea, Osteoarthritis, Female Infertility, and other Conditions, including: idiopathic intracranial hypertension lower extremity venous stasis disease, gastroesophageal reflux and urinary stress incontinence. This new book gathers research from around the world in the critical field of obesity research and its effects.
