Variables that have been conceptually linked with social vulnerability—income, educational level, employment, cessation of work to provide care, marital status, social support, and health—were used to predict four categories of reaction to caregiving in 159 daughters and daughters‐in‐law caring for their disabled aging parents. Social support, income, and health best predicted negative reactions to caregiving; social support alone best predicted feelings of family abandonment, impact on health, and impact on schedule. Compared with daughters and daughters‐in‐law who had not quit work to provide care, those who had quit work were significantly older, had lower incomes and fewer social supports, and were more involved in care. The results suggest that quitting work may be a precursor to social isolation that places the caregiver at increased risk for social vulnerability and negative reaction to caregiving. The implications of the findings for health care policy are discussed. 相似文献

Hypertension treatment regimens used by African American adults in the Jackson Heart Study were evaluated at the first two clinical examinations (2415 treated hypertensive persons at examination I [exam I], 2000–2004; 2577 at examination II [exam II], 2005–2008). Blood pressure (BP) was below 140/90 mm Hg for 66% and 70% of treated participants at exam I and exam II, respectively. The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure treatment targets were met for 56% and 61% at exam I and exam II, respectively. Persons with diabetes or chronic kidney disease were less likely to have BP at target, as were men compared with women. Thiazide diuretics were the most commonly used antihypertensive medication, and persons taking a thiazide were more likely to have their BP controlled than persons not taking them; thiazides were used significantly less among men than women. Although calcium channel blockers are often considered to be effective monotherapy for African Americans, persons using calcium channel blocker monotherapy were significantly less likely to be at target BP than persons using thiazide monotherapy. 相似文献
