RESUMEN

Importance: According to National Health and Nutrition Examination Survey data, 52% of surveyed US adults reported using at least 1 dietary supplement in the prior 30 days and 31% reported using a multivitamin-mineral supplement. The most commonly cited reason for using supplements is for overall health and wellness and to fill nutrient gaps in the diet. Cardiovascular disease and cancer are the 2 leading causes of death and combined account for approximately half of all deaths in the US annually. Inflammation and oxidative stress have been shown to have a role in both cardiovascular disease and cancer, and dietary supplements may have anti-inflammatory and antioxidative effects. Objective: To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a review of the evidence on the efficacy of supplementation with single nutrients, functionally related nutrient pairs, or multivitamins for reducing the risk of cardiovascular disease, cancer, and mortality in the general adult population, as well as the harms of supplementation. Population: Community-dwelling, nonpregnant adults. Evidence Assessment: The USPSTF concludes with moderate certainty that the harms of beta carotene supplementation outweigh the benefits for the prevention of cardiovascular disease or cancer. The USPSTF also concludes with moderate certainty that there is no net benefit of supplementation with vitamin E for the prevention of cardiovascular disease or cancer. The USPSTF concludes that the evidence is insufficient to determine the balance of benefits and harms of supplementation with multivitamins for the prevention of cardiovascular disease or cancer. Evidence is lacking and the balance of benefits and harms cannot be determined. The USPSTF concludes that the evidence is insufficient to determine the balance of benefits and harms of supplementation with single or paired nutrients (other than beta carotene and vitamin E) for the prevention of cardiovascular disease or cancer. Evidence is lacking and the balance of benefits and harms cannot be determined. Recommendation: The USPSTF recommends against the use of beta carotene or vitamin E supplements for the prevention of cardiovascular disease or cancer. (D recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of the use of multivitamin supplements for the prevention of cardiovascular disease or cancer. (I statement) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of the use of single- or paired-nutrient supplements (other than beta carotene and vitamin E) for the prevention of cardiovascular disease or cancer. (I statement).

RESUMEN

Importance: Perinatal depression, which is the occurrence of a depressive disorder during pregnancy or following childbirth, affects as many as 1 in 7 women and is one of the most common complications of pregnancy and the postpartum period. It is well established that perinatal depression can result in adverse short- and long-term effects on both the woman and child. Objective: To issue a new US Preventive Services Task Force (USPSTF) recommendation on interventions to prevent perinatal depression. Evidence Review: The USPSTF reviewed the evidence on the benefits and harms of preventive interventions for perinatal depression in pregnant or postpartum women or their children. The USPSTF reviewed contextual information on the accuracy of tools used to identify women at increased risk of perinatal depression and the most effective timing for preventive interventions. Interventions reviewed included counseling, health system interventions, physical activity, education, supportive interventions, and other behavioral interventions, such as infant sleep training and expressive writing. Pharmacological approaches included the use of nortriptyline, sertraline, and omega-3 fatty acids. Findings: The USPSTF found convincing evidence that counseling interventions, such as cognitive behavioral therapy and interpersonal therapy, are effective in preventing perinatal depression. Women with a history of depression, current depressive symptoms, or certain socioeconomic risk factors (eg, low income or young or single parenthood) would benefit from counseling interventions and could be considered at increased risk. The USPSTF found adequate evidence to bound the potential harms of counseling interventions as no greater than small, based on the nature of the intervention and the low likelihood of serious harms. The USPSTF found inadequate evidence to assess the benefits and harms of other noncounseling interventions. The USPSTF concludes with moderate certainty that providing or referring pregnant or postpartum women at increased risk to counseling interventions has a moderate net benefit in preventing perinatal depression. Conclusions and Recommendation: The USPSTF recommends that clinicians provide or refer pregnant and postpartum persons who are at increased risk of perinatal depression to counseling interventions. (B recommendation).

RESUMEN

Importance: Falls are the leading cause of injury-related morbidity and mortality among older adults in the United States. In 2014, 28.7% of community-dwelling adults 65 years or older reported falling, resulting in 29 million falls (37.5% of which needed medical treatment or restricted activity for a day or longer) and an estimated 33 000 deaths in 2015. Objective: To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on the prevention of falls in community-dwelling older adults. Evidence Review: The USPSTF reviewed the evidence on the effectiveness and harms of primary care-relevant interventions to prevent falls and fall-related morbidity and mortality in community-dwelling older adults 65 years or older who are not known to have osteoporosis or vitamin D deficiency. Findings: The USPSTF found adequate evidence that exercise interventions have a moderate benefit in preventing falls in older adults at increased risk for falls and that multifactorial interventions have a small benefit. The USPSTF found adequate evidence that vitamin D supplementation has no benefit in preventing falls in older adults. The USPSTF found adequate evidence to bound the harms of exercise and multifactorial interventions as no greater than small. The USPSTF found adequate evidence that the overall harms of vitamin D supplementation are small to moderate. Conclusions and Recommendation: The USPSTF recommends exercise interventions to prevent falls in community-dwelling adults 65 years or older who are at increased risk for falls. (B recommendation) The USPSTF recommends that clinicians selectively offer multifactorial interventions to prevent falls in community-dwelling adults 65 years or older who are at increased risk for falls. Existing evidence indicates that the overall net benefit of routinely offering multifactorial interventions to prevent falls is small. When determining whether this service is appropriate for an individual, patients and clinicians should consider the balance of benefits and harms based on the circumstances of prior falls, presence of comorbid medical conditions, and the patient's values and preferences. (C recommendation) The USPSTF recommends against vitamin D supplementation to prevent falls in community-dwelling adults 65 years or older. (D recommendation) These recommendations apply to community-dwelling adults who are not known to have osteoporosis or vitamin D deficiency.

RESUMEN

Importance: Because of the aging population, osteoporotic fractures are an increasingly important cause of morbidity and mortality in the United States. Approximately 2 million osteoporotic fractures occurred in the United States in 2005, and annual incidence is projected to increase to more than 3 million fractures by 2025. Within 1 year of experiencing a hip fracture, many patients are unable to walk independently, more than half require assistance with activities of daily living, and 20% to 30% of patients will die. Objective: To update the 2013 US Preventive Services Task Force (USPSTF) recommendation on vitamin D supplementation, with or without calcium, to prevent fractures. Evidence Review: The USPSTF reviewed the evidence on vitamin D, calcium, and combined supplementation for the primary prevention of fractures in community-dwelling adults (defined as not living in a nursing home or other institutional care setting). The review excluded studies conducted in populations with a known disorder related to bone metabolism (eg, osteoporosis or vitamin D deficiency), taking medications known to be associated with osteoporosis (eg, long-term steroids), or with a previous fracture. Findings: The USPSTF found inadequate evidence to estimate the benefits of vitamin D, calcium, or combined supplementation to prevent fractures in community-dwelling men and premenopausal women. The USPSTF found adequate evidence that daily supplementation with 400 IU or less of vitamin D and 1000 mg or less of calcium has no benefit for the primary prevention of fractures in community-dwelling, postmenopausal women. The USPSTF found inadequate evidence to estimate the benefits of doses greater than 400 IU of vitamin D or greater than 1000 mg of calcium to prevent fractures in community-dwelling postmenopausal women. The USPSTF found adequate evidence that supplementation with vitamin D and calcium increases the incidence of kidney stones. Conclusions and Recommendation: The USPSTF concludes that the current evidence is insufficient to assess the balance of the benefits and harms of vitamin D and calcium supplementation, alone or combined, for the primary prevention of fractures in community-dwelling, asymptomatic men and premenopausal women. (I statement) The USPSTF concludes that the current evidence is insufficient to assess the balance of the benefits and harms of daily supplementation with doses greater than 400 IU of vitamin D and greater than 1000 mg of calcium for the primary prevention of fractures in community-dwelling, postmenopausal women. (I statement) The USPSTF recommends against daily supplementation with 400 IU or less of vitamin D and 1000 mg or less of calcium for the primary prevention of fractures in community-dwelling, postmenopausal women. (D recommendation) These recommendations do not apply to persons with a history of osteoporotic fractures, increased risk for falls, or a diagnosis of osteoporosis or vitamin D deficiency.

RESUMEN

Importance: Neural tube defects are among the most common major congenital anomalies in the United States and may lead to a range of disabilities or death. Daily folic acid supplementation in the periconceptional period can prevent neural tube defects. However, most women do not receive the recommended daily intake of folate from diet alone. Objective: To update the 2009 US Preventive Services Task Force (USPSTF) recommendation on folic acid supplementation in women of childbearing age. Evidence Review: In 2009, the USPSTF reviewed the effectiveness of folic acid supplementation in women of childbearing age for the prevention of neural tube defects in infants. The current review assessed new evidence on the benefits and harms of folic acid supplementation. Findings: The USPSTF assessed the balance of the benefits and harms of folic acid supplementation in women of childbearing age and determined that the net benefit is substantial. Evidence is adequate that the harms to the mother or infant from folic acid supplementation taken at the usual doses are no greater than small. Therefore, the USPSTF reaffirms its 2009 recommendation. Conclusions and Recommendation: The USPSTF recommends that all women who are planning or capable of pregnancy take a daily supplement containing 0.4 to 0.8 mg (400-800 µg) of folic acid. (A recommendation).

RESUMEN

OBJECTIVES: Although care coordination is an essential component of the patient-centered medical home structure, current case manager models have limited usefulness to population health because they typically serve a small group of patients defined based on disease or utilization. Our objective was to support our health system's population health by implementing and evaluating a program that embedded nonlicensed coordinators within our primary care practices to support physicians in executing care plans and communicating with patients. STUDY DESIGN: Matched case-control differences-in-differences. METHODS: Comprehensive care coordinators (CCC) were introduced into 14 of the system's 28 practice sites in 2 waves. After a structured training program, CCCs identified, engaged, and intervened among patients within the practice in conjunction with practice primary care providers. We counted and broadly coded CCC activities that were documented in the intervention database. We examined the impact of CCC intervention on emergency department (ED) utilization at the practice level using a negative binomial multivariate regression model controlling for age, gender, and medical complexity. RESULTS: CCCs touched 10,500 unique patients over a 1-year period. CCC interventions included execution of care (38%), coordination of transitions (32%), self-management support/link to community resources (15%), monitor and follow-up (10%), and patient assessment (1%). The CCC intervention group had a 20% greater reduction in its prepost ED visit rate compared with the control group (P < .0001). CONCLUSIONS: Our CCC intervention demonstrated a significant reduction in ED visits by focusing on the centrality of the primary care provider and practice. Our model may serve as a cost-effective and scalable alternative for care coordination in primary care.

RESUMEN

OBJECTIVE: The aim of this study was to examine the association between religiosity and overweight or obese body mass index among a multi-religious group of Asian Indian immigrants residing in California. METHODS: We examined cross-sectional survey data obtained from in-language telephone interviews with 3228 mostly immigrant Asian Indians in the 2004 California Asian Indian Tobacco Survey using multivariate logistic regression. RESULTS: High self-identified religiosity was significantly associated with higher BMI after adjusting for socio-demographic and acculturation measures. Highly religious Asian Indians had 1.53 greater odds (95% CI: 1.18, 2.00) of being overweight or obese than low religiosity immigrants, though this varied by religious affiliation. Religiosity was associated with greater odds of being overweight/obese for Hindus (OR 1.54; 95% CI: 1.08, 2.22) and Sikhs (OR 1.88; 95% CI: 1.07, 3.30), but not for Muslims (OR 0.69; 95% CI: 0.28, 1.70). CONCLUSIONS: Religiosity in Hindus and Sikhs, but not immigrant Muslims, appears to be independently associated with greater body mass index among Asian Indians. If this finding is confirmed, future research should identify potentially mutable mechanisms by which religion-specific religiosity affects overweight/obesity risk.

RESUMEN

OBJECTIVES: To evaluate a faith-based intervention (Sisters in Motion) intended to increase walking in older, sedentary African-American women. DESIGN: Randomized controlled trial using within-church randomization. SETTING: Three Los Angeles churches. PARTICIPANTS: Sixty-two African-American women aged 60 and older who reported being active less than 30 minutes three times per week and walked less than 35,000 steps per week as measured using a baseline pedometer reading. INTERVENTION: Intervention participants received a multicomponent curriculum including scripture readings, prayer, goal-setting, a community resource guide, and walking competitions. Intervention and control participants both participated in physical activity sessions. MEASUREMENTS: The primary outcome was change in weekly steps walked as measured using the pedometer. Secondary outcomes included change in systolic blood pressure (SBP). Outcomes were assessed at baseline and 6 months after the intervention. RESULTS: Eighty-five percent of participants attended at least six of eight sessions. Intervention participants averaged 12,727 steps per week at baseline, compared with 13,089 steps in controls. Mean baseline SBP was 156 mmHg for intervention participants and 147 mmHg for controls (P=.10). At 6 months, intervention participants had increased their weekly steps by 9,883 on average, compared with an increase of 2,426 for controls (P=.02); SBP decreased on average by 12.5 mmHg in intervention participants and only 1.5 mmHg in controls (P=.007). CONCLUSION: The Sisters in Motion intervention led to an increase in walking and a decrease in SBP at 6 months. This is the first randomized controlled trial of a faith-based physical activity program to increase physical activity in older African-American women and represents an attractive approach to stimulate lifestyle change in this population.

RESUMEN

Syncope is a common reason for emergency department (ED) visits, and patients are often admitted to exclude syncope of cardiovascular origin. Population-based data on patterns and predictors of cardiac outcomes may improve decision-making. Our objective was to identify patterns and predictors of short-term cardiac outcomes in ED patients with syncope. Administrative data from an integrated health system of 11 Southern California EDs were used to identify cardiac outcomes after ED presentation for syncope from January 1, 2002, to December 31, 2005. Syncope and cause of death were identified by codes from the International Classification of Disease, Ninth Revision. Cardiac outcomes included cardiac death and hospitalization or procedure consistent with ischemic heart disease, valvular disease, or arrhythmia. Predictors of cardiac outcomes were identified through multivariate logistic regression. There were 35,330 adult subjects who accounted for 39,943 ED visits for syncope. Risk of cardiac outcome sharply decreased following the 7 days after syncope. A 7-day cardiac outcome occurred in 893 cases (3%). Positive predictors of 7-day cardiac outcomes included age > or =60 years, male gender, congestive heart failure, ischemic heart disease, cardiac arrhythmia, and valvular heart disease. Negative predictors included dementia, pacemaker, coronary revascularization, and cerebrovascular disease. There was an age-dependent relation between 7-day cardiac outcomes and arrhythmia and valvular disease, with younger patients (<60 years of age) having greater risk of an event compared to their same-age counterparts. In conclusion, ED decision-making should focus on risk of cardiac event in the first 7 days after syncope and special attention should be given to younger patients with cardiac co-morbidities.

RESUMEN

PURPOSE: Despite mandated reporting laws that require physicians to report elder abuse, physicians have low rates of reporting. The purpose of this study was to identify physician's perspectives on mandated reporting of elder abuse. METHODS: Individual, semistructured interviews were conducted with 20 primary care physicians practicing in a variety of settings and caring for a diverse patient population in the Los Angeles area. Interviewers collected information on physicians' perspectives about factors that may influence physicians' likelihood to report elder abuse. The interviews were recorded and transcribed verbatim. Transcripts were analyzed using a grounded theory approach based on the constant comparative method and the emergence of the core category of paradox to best account for the most problematic elder abuse situations faced by physicians. RESULTS: During the interviews 3 paradoxes were expressed by physicians about the mandatory reporting of elder abuse. Specifically, mandatory reporting was related to both perceptions of increases and decreases in physician-patient rapport, patient quality of life, and physician control or ability to decide what is in the best interest of the patient. These paradoxes appear to be primarily hidden or unconscious, yet they influence the conscious decision process of whether to report. CONCLUSIONS: Primary care physicians appear to be subject to paradoxes of reporting that contribute to the underreporting of elder abuse. These paradoxes and alternative modes of managing paradoxes are important and should be addressed in educational and training programs for physicians, and systematic evaluation of these issues may help to inform future legislation in this area. Further studies are needed to assess the generalizability of these findings to other groups of clinicians.

RESUMEN

BACKGROUND: Serum cholesterol is one of the most important modifiable risk factors for coronary artery disease. There are conflicting data on racial and ethnic variation in the treatment of high cholesterol. METHODS: We analyzed data from the Third National Health and Nutrition Examination Survey, a nationally representative cross-sectional survey conducted between 1988 and 1994. Participants included 7679 white, 4467 African American, and 4113 Mexican American adults older than 25 years who completed the household adult questionnaire. The adjusted odds of serum cholesterol screening and of taking a prescription medication to lower serum cholesterol among African Americans and Mexican Americans were compared with those of whites, controlling for differences in age, sex, income, educational level, insurance status, comorbid illness, and having a regular source of health care. RESULTS: African Americans and Mexican Americans were significantly less likely than whites to report ever having had their blood cholesterol checked (odds ratio, 0.7 for both; P<.001). Among individuals with high cholesterol who were told to take a medication, African Americans (P<.001) and Mexican Americans (P =.05) were less likely than whites to be taking a cholesterol-lowering agent (odds ratios, 0.3 and 0.5, respectively). Individuals who reported being told they had high cholesterol had significantly higher serum cholesterol measurements (from the laboratory examination) than those who reported being told their cholesterol was not high (234 vs 198 mg/dL [6.05 vs 5.12 mmol/L]; P<.001). CONCLUSIONS: African Americans and Mexican Americans were less likely to report serum cholesterol screening than whites. Even when identified as having high cholesterol that required medication, African Americans and Mexican Americans were less likely than whites to be taking cholesterol-lowering agents.
