Low-Dose Hormone Replacement Therapy Increases Bone Density in Elderly Women
Continuous low-dose hormone replacement therapy (HRT), together with adequate calcium and vitamin D, increased bone mass as effectively as higher-dose HRT therapy in elderly women, a new study shows (Article, p. 897). These are the most positive results for low-dose HRT reported to date. Low-dose HRT may have fewer toxic side effects than higher-dose therapy.
Two More Reasons to Get Active and Lose Weight
Physical Activity Biggest Influence on Weight; May Overcome Genetic Factors
A study of some 1000 healthy, female twins found that physical activity -- not smoking status, socioeconomic factors, hormone replacement therapy status or diet -- was the greatest environmental determinant of total-body weight and mid-section fat (Article, p. 873). In the subgroup of identical twins, even women with a genetic predisposition to obesity who exercised had lower body-mass-weight values, indicating that exercise can benefit people with a strong family history of obesity.
Overweight and an Esophageal Cancer Linked
A large, population-based study of people with adenocarcinoma of the esophagus, a cancer that is increasing dramatically in several Western countries, found a strong association between the cancer and body weight, measured as body mass index (BMI) (Article, p. 883). A weak correlation was found between BMI and cancer of the gastric cardia. No correlation was found between BMI and another cancer of the esophagus, squamous-cell carcinoma.
