Little is known about the combined associations of cardiorespiratory fitness (CRF) and hand grip strength (GS) with mortality in general adult populations. The purpose of this study was to compare the relative risk of mortality for CRF, GS, and their combination. In UK Biobank, a prospective cohort of >?0.5 million adults aged 40–69 years, CRF was measured through submaximal bike tests; GS was measured using a hand-dynamometer. This analysis is based on data from 70,913 men and women (832 all-cause, 177 cardiovascular and 503 cancer deaths over 5.7-year follow-up) who provided valid CRF and GS data, and with no history of heart attack/stroke/cancer at baseline. Compared with the lowest CRF category, the hazard ratio (HR) for all-cause mortality was 0.76 [95% confidence interval (CI) 0.64–0.89] and 0.65 (95% CI 0.55–0.78) for the middle and highest CRF categories, respectively, after adjustment for confounders and GS. The highest GS category had an HR of 0.79 (95% CI 0.66–0.95) for all-cause mortality compared with the lowest, after adjustment for confounders and CRF. Similar results were found for cardiovascular and cancer mortality. The HRs for the combination of highest CRF and GS were 0.53 (95% CI 0.39–0.72) for all-cause mortality and 0.31 (95% CI 0.14–0.67) for cardiovascular mortality, compared with the reference category of lowest CRF and GS: no significant association for cancer mortality (HR 0.70; 95% CI 0.48–1.02). CRF and GS are both independent predictors of mortality. Improving both CRF and muscle strength, as opposed to either of the two alone, may be the most effective behavioral strategy to reduce all-cause and cardiovascular mortality risk.  相似文献

Objectives

The availability of suicide prevention training programs for pharmacists is unknown and may depend on state training requirements. This study’s objectives were to: 1) report state training requirements for pharmacist suicide education; and 2) describe educational resources that are available to prepare pharmacists for interactions with patients at risk of suicide.

Methods

Each state’s board of pharmacy was contacted from July to November 2017 to determine whether that state required pharmacists to complete suicide prevention training. A scoping literature review completed in August 2017 identified suicide prevention resources for pharmacy professionals. A systematic search of 5 databases and Google yielded publications and online resources that were screened for full review. Two coders reviewed articles and resources that met inclusion criteria and extracted data on program format and length, intended audience (i.e., students, practicing pharmacists), learning methods, topics covered, and outcomes assessed.

Results

Only Washington State requires pharmacists to obtain suicide prevention training. Sixteen suicide education programs and resources targeted pharmacists, including 8 in-person courses, 6 online courses, and 2 written resources. Five resources exclusively targeted pharmacists and 2 exclusively targeted student pharmacists. Most programs included information on suicide statistics, how to identify individuals at risk of suicide, how to communicate with someone who is suicidal, and how to refer patients to treatment resources. The long-term effectiveness of the programs at improving outcomes was not reported.

Conclusion

Although only 1 state requires pharmacists to obtain training on suicide prevention, there are several resources available to help prepare pharmacists to interact with individuals at risk of suicide.  相似文献
