It has not been scientifically established that large amounts of vitamins and minerals or dietary supplements help prevent or treat health problems or slow the aging process. Daily multivitamin tablets can be beneficial to some people who do not consume a balanced diet or a variety of foods. Generally, eating a well-balanced diet with a variety of foods provides the necessary nutrients your body needs. Eating whole foods is preferable to supplements because foods provide dietary fiber and other nutritional benefits that supplements do not. If you choose to take vitamin and mineral supplements, it is recommended to choose a multi-vitamin that does not exceed 100 percent of the Recommended Dietary Intake (RDI).
Not being able to do a pull-up doesn’t mean you shouldn’t step up to the bar. Simply hanging on for as long as possible can improve your upper-body strength, Montenegro says. Concentrate on keeping your body as still as possible, and you’ll naturally recruit your abs, hips, and lower back in addition to your arms, she explains, or slowly move your legs in circles or up and down to further engage your abs.
Child marriage (including union or cohabitation) is defined as marriage under the age of eighteen and is an ancient custom. In 2010 it was estimated that 67 million women, then, in their twenties had been married before they turned eighteen, and that 150 million would be in the next decade, equivalent to 15 million per year. This number had increased to 70 million by 2012. In developing countries one third of girls are married under age, and 1:9 before 15. The practice is commonest in South Asia (48% of women), Africa (42%) and Latin America and the Caribbean (29%). The highest prevalence is in Western and Sub-Saharan Africa. The percentage of girls married before the age of eighteen is as high as 75% in countries such as Niger (Nour, Table I). Most child marriage involves girls. For instance in Mali the ratio of girls to boys is 72:1, while in countries such as the United States the ratio is 8:1. Marriage may occur as early as birth, with the girl being sent to her husbands home as early as age seven.
After menopause. Lower levels of estrogen after menopause raise your risk for chronic diseases such as heart disease, stroke, and diabetes, and osteoporosis, a condition that causes your bones to become weak and break easily. What you eat also affects these chronic diseases. Talk to your doctor about healthy eating plans and whether you need more calcium and vitamin D to protect your bones. Read more about how very low estrogen levels affect your health in our Menopause section. Most women also need fewer calories as they age, because of less muscle and less physical activity. Find out how many calories you need based on your level of activity.
Osteoporosis ranks sixth amongst chronic diseases of women in the United States, with an overall prevalence of 18%, and a much higher rate involving the femur, neck or lumbar spine amongst women (16%) than men (4%), over the age of 50 (Gronowski and Schindler, Table IV). Osteoporosis is a risk factor for bone fracture and about 20% of senior citizens who sustain a hip fracture die within a year.  The gender gap is largely the result of the reduction of estrogen levels in women following the menopause. Hormone Replacement Therapy (HRT) has been shown to reduce this risk by 25–30%, and was a common reason for prescribing it during the 1980s and 1990s. However the Women's Health Initiative (WHI) study that demonstrated that the risks of HRT outweighed the benefits has since led to a decline in HRT usage.
In addition to diet, exercise and other lifestyle factors can also play an important role in bone health. Smoking and drinking too much alcohol can increase your chances of developing osteoporosis, while weight-bearing exercise (such as walking, dancing, yoga, or lifting weights) can lower your risk. Strength or resistance training—using machines, free weights, elastic bands, or your own body weight—can be especially effective in helping to prevent loss of bone mass as you age.
