As with all age groups, women of high income and with low income have low birth weight. They also stress that higher education levels of men and their longer life expectancy might protect against this risk due to increased risk of obesity, diabetes and other metabolic disorders. But the study also found that the effects of socioeconomic disadvantage have been poorly studied, with most adults lacking access to a standard health-care intervention. Studies suggest people with higher educational levels are less likely to meet health-care needs or to engage in behaviors related to chronic health conditions, such as exercise or weight loss. As it happens, many of these people are also poor on average, and many have no other means of obtaining health care. This study suggests that poor financial support for elderly people is also strongly associated with poorer health outcomes, especially for those with lower earnings, says David Segal, PhD, a professor emeritus at the Columbia School of Medicine and the lead author of the report. However, such a strong inverse association between a low income and health outcomes is important in order to address inequities in health care. The researchers also said that their research was preliminary and preliminary, but that it would be useful to better understand the relationship that people could have with their children, or health risks.
