Body weight and obesity in adults and self-reported abuse in childhood.

BACKGROUND: Little is known about childhood factors and adult obesity. A previous study found a strong association between childhood neglect and obesity in young adults. OBJECTIVE: To estimate associations between self-reported abuse in childhood (sexual, verbal, fear of physical abuse and physical) adult body weight, and risk of obesity. DESIGN: Retrospective cohort study with surveys during 1995-1997. PATIENTS: A total of 13,177 members of California health maintenance organization aged 19-92 y. MEASUREMENTS: Body weight measured during clinical examination, followed by mailed survey to recall experiences during first 18 y of life. Estimates adjusted for adult demographic factors and health practices, and characteristics of the childhood household. RESULTS: Some 66% of participants reported one or more type of abuse. Physical abuse and verbal abuse were most strongly associated with body weight and obesity. Compared with no physical abuse (55%), being 'often hit and injured' (2.5%) had a 4.0 kg (95% confidence interval: 2.4-5.6 kg) higher weight and a 1.4 (1.2-1.6) relative risk (RR) of body mass index (BMI) > or = 30. Compared with no verbal abuse (53%), being 'often verbally abused' (9.5%) had an RR of 1.9 (1.3-2.7) for BMI > or = 40. The abuse associations were not mutually independent, however, because the abuse types strongly co-occurred. Obesity risk increased with number and severity of each type of abuse. The population attributable fraction for 'any mention' of abuse (67%) was 8% (3.4-12.3%) for BMI > or = 30 and 17.3% (-1.0-32.4%) for BMI > or = 40. CONCLUSIONS: Abuse in childhood is associated with adult obesity. If causal, preventing child abuse may modestly decrease adult obesity. Treatment of obese adults abused as children may benefit from identification of mechanisms that lead to maintenance of adult obesity.

Adverse childhood experiences and sexual risk behaviors in women: a retrospective cohort study.

CONTEXT: Adverse childhood experiences such as physical abuse and sexual abuse have been shown to be related to subsequent unintended pregnancies and infection with sexually transmitted diseases. However, the extent to which sexual risk behaviors in women are associated with exposure to adverse experiences during childhood is not well-understood. METHODS: A total of 5,060 female members of a managed care organization provided information about seven categories of adverse childhood experiences: having experienced emotional, physical or sexual abuse; or having had a battered mother or substance-abusing, mentally ill or criminal household members. Logistic regression was used to model the association between cumulative categories of up to seven adverse childhood experiences and such sexual risk behaviors as early onset of intercourse, 30 or more sexual partners and self-perception as being at risk for AIDS. RESULTS: Each category of adverse childhood experiences was associated with an increased risk of intercourse by age 15 (odds ratios, 1.6-2.6), with perceiving oneself as being at risk of AIDS (odds ratios, 1.5-2.6) and with having had 30 or more partners (odds ratios, 1.6-3.8). After adjustment for the effects of age at interview and race, women who experienced rising numbers of types of adverse childhood experiences were increasingly likely to see themselves as being at risk of AIDS: Those with one such experience had a slightly elevated likelihood (odds ratio, 1.2), while those with 4-5 or 6-7 such experiences had substantially elevated odds (odds ratios, 1.8 and 4.9, respectively). Similarly, the number of types of adverse experiences was tied to the likelihood of having had 30 or more sexual partners, rising from odds of 1.6 for those with one type of adverse experience and 1.9 for those with two to odds of 8.2 among those with 6-7. Finally, the chances that a woman first had sex by age 15 also rose progressively with increasing numbers of such experiences, from odds of 1.8 among those with one type of adverse childhood experience to 7.0 among those with 6-7. CONCLUSIONS: Among individuals with a history of adverse childhood experiences, risky sexual behavior may represent their attempts to achieve intimate interpersonal connections. Having grown up in families unable to provide needed protection, such individuals may be unprepared to protect themselves and may underestimate the risks they take in their attempts to achieve intimacy. If so, coping with such problems represents a serious public health challenge.

Abused boys, battered mothers, and male involvement in teen pregnancy.

BACKGROUND: The relationship between boyhood exposure to physical abuse, sexual abuse, or to a battered mother and subsequent risk of impregnating a teenage girl has not previously been examined. METHODS: In a retrospective cohort study set in a primary care clinic for adult members of a large health maintenance organization, questionnaire responses from 4127 men were analyzed. Respondents provided the age of the youngest female whom they had impregnated, their own ages at the time, and information regarding childhood exposure to physical or sexual abuse and battered mothers. We calculated the prevalence and adjusted odds ratio (OR) for having impregnated a teenage girl according to these 3 adverse childhood experiences, regardless of the male's age at the time of impregnation. Using logistic regression, ORs were adjusted for the male's age at time of survey, race, and education. RESULTS: Nineteen percent of the men reported that they had ever impregnated a teenage girl. During childhood, 32% of respondents had been physically abused, 15% sexually abused, and 11% had battered mothers. Compared with respondents reporting no abuse, frequent physical abuse or battering of mothers increased the risk of involvement in teen pregnancy by 70% (OR: 1.7; 95% confidence interval [CI]: 1.2-2.5) and 140% (OR: 2.4; 95% CI: 1.1-5.0), respectively. Sexual abuse as a boy at age 10 years or younger increased the risk of impregnating a teenage girl by 80% (OR: 1.8; 95% CI: 1.3-2.4); sexual abuse with violence increased the risk by 110% (OR: 2.1; 95% CI: 1.2-3.4). We found a dose-response relationship between the number of types of exposures and the risk of impregnating a teenage girl; men who reported all 3 types of exposures were more than twice as likely to have been involved than those with no exposures (OR: 2.2; 95% CI: 1.4-3.5). CONCLUSIONS: Boyhood exposure to physical or sexual abuse or to a battered mother is associated with an increased risk of involvement in a teen pregnancy-during both adolescence and adulthood. Because these exposures are common and interrelated, boys and adult men who have had these experiences should be identified via routine screening by pediatricians and other health care providers and counseled about sexual practices and contraception. Such efforts may prevent teen pregnancy and the intergenerational transmission of child abuse and domestic violence.

Growing up with parental alcohol abuse: exposure to childhood abuse, neglect, and household dysfunction.

OBJECTIVE: This study is a detailed examination of the association between parental alcohol abuse (mother only, father only, or both parents) and multiple forms of childhood abuse, neglect, and other household dysfunction, known as adverse childhood experiences (ACEs). METHOD: A questionnaire about ACEs including child abuse, neglect, household dysfunction, and exposure to parental alcohol abuse was completed by 8629 adult HMO members to retrospectively assess the relationship of growing up with parental alcohol abuse to 10 ACEs and multiple ACEs (ACE score). RESULTS: Compared to persons who grew up with no parental alcohol abuse, the adjusted odds ratio for each category of ACE was approximately 2 to 13 times higher if either the mother, father, or both parents abused alcohol (p < 0.05). For example, the likelihood of having a battered mother was increased 13-fold for men who grew up with both parents who abused alcohol (OR, 12.7; 95% CI: 8.4-19.1). For almost every ACE, those who grew up with both an alcohol-abusing mother and father had the highest likelihood of ACEs. The mean number of ACEs for persons with no parental alcohol abuse, father only, mother only, or both parents was 1.4, 2.6, 3.2, and 3.8, respectively (p < .001). CONCLUSION: Although the retrospective reporting of these experiences cannot establish a causal association with certainty, exposure to parental alcohol abuse is highly associated with experiencing adverse childhood experiences. Improved coordination of adult and pediatric health care along with related social and substance abuse services may lead to earlier recognition, treatment, and prevention of both adult alcohol abuse and adverse childhood experiences, reducing the negative sequelae of ACEs in adolescents and adults.

Childhood abuse, household dysfunction, and the risk of attempted suicide throughout the life span: findings from the Adverse Childhood Experiences Study.

CONTEXT: Suicide is a leading cause of death in the United States, but identifying persons at risk is difficult. Thus, the US surgeon general has made suicide prevention a national priority. An expanding body of research suggests that childhood trauma and adverse experiences can lead to a variety of negative health outcomes, including attempted suicide among adolescents and adults. OBJECTIVE: To examine the relationship between the risk of suicide attempts and adverse childhood experiences and the number of such experiences (adverse childhood experiences [ACE] score). DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study of 17 337 adult health maintenance organization members (54% female; mean [SD] age, 57 [15.3] years) who attended a primary care clinic in San Diego, Calif, within a 3-year period (1995-1997) and completed a survey about childhood abuse and household dysfunction, suicide attempts (including age at first attempt), and multiple other health-related issues. MAIN OUTCOME MEASURE: Self-reported suicide attempts, compared by number of adverse childhood experiences, including emotional, physical, and sexual abuse; household substance abuse, mental illness, and incarceration; and parental domestic violence, separation, or divorce. RESULTS: The lifetime prevalence of having at least 1 suicide attempt was 3.8%. Adverse childhood experiences in any category increased the risk of attempted suicide 2- to 5-fold. The ACE score had a strong, graded relationship to attempted suicide during childhood/adolescence and adulthood (P<.001). Compared with persons with no such experiences (prevalence of attempted suicide, 1.1%), the adjusted odds ratio of ever attempting suicide among persons with 7 or more experiences (35.2%) was 31.1 (95% confidence interval, 20.6-47.1). Adjustment for illicit drug use, depressed affect, and self-reported alcoholism reduced the strength of the relationship between the ACE score and suicide attempts, suggesting partial mediation of the adverse childhood experience-suicide attempt relationship by these factors. The population-attributable risk fractions for 1 or more experiences were 67%, 64%, and 80% for lifetime, adult, and childhood/adolescent suicide attempts, respectively. CONCLUSIONS: A powerful graded relationship exists between adverse childhood experiences and risk of attempted suicide throughout the life span. Alcoholism, depressed affect, and illicit drug use, which are strongly associated with such experiences, appear to partially mediate this relationship. Because estimates of the attributable risk fraction caused by these experiences were large, prevention of these experiences and the treatment of persons affected by them may lead to progress in suicide prevention.

Adverse childhood experiences and sexually transmitted diseases in men and women: a retrospective study.

OBJECTIVE: Adverse childhood experiences (ACEs) may have long-term consequences on at-risk behaviors that lead to an increased risk of sexually transmitted diseases (STDs) during adulthood. Therefore, we examined the relationship between ACEs and subsequent STDs for both men and women. METHODS: A total of 9323 (4263 men and 5060 women) adults >/=18 years of age participated in a retrospective cohort study evaluating the association between ACEs and self-reported STDs. Participants were adult members of a managed care organization who underwent routine medical evaluations and completed standardized questionnaires about 7 categories of ACEs, including emotional, physical, or sexual abuse; living with a battered mother; and living with a substance-abusing, mentally ill, or criminal household member. Logistic regression was used to model the association between the cumulative categories of ACEs (range: 0-7) and a history of STDs. RESULTS: We found that 59% (2986) of women and 57% (2464) of men reported 1 or more categories of adverse experiences during childhood. Among those with 0, 1, 2, 3, 4 to 5, and 6 to 7 ACEs, the proportion with STDs was 4.1%, 6.9%, 8.0%, 11.6%, 13.5%, and 20.7% for women and 7.3%, 10.9%, 12.9%, 17.1%, 17.1%, and 39.1% for men. After adjustment for age and race, all odds ratios for reporting an STD had confidence intervals that excluded 1. Among those with 1, 2, 3, 4 to 5, and 6 to 7 ACEs, the odds ratios were 1.45, 1.54, 2.22, 2. 48, and 3.40 for women and 1.46, 1.67, 2.16, 2.07, and 5.3 for men. CONCLUSIONS: We observed a strong graded relationship between ACEs and a self-reported history of STDs among adults.

Adverse childhood experiences and smoking during adolescence and adulthood.

CONTEXT: In recent years, smoking among adolescents has increased and the decline of adult smoking has slowed to nearly a halt; new insights into tobacco dependency are needed to correct this situation. Long-term use of nicotine has been linked with self-medicating efforts to cope with negative emotional, neurobiological, and social effects of adverse childhood experiences. OBJECTIVE: To assess the relationship between adverse childhood experiences and 5 smoking behaviors. DESIGN: The ACE Study, a retrospective cohort survey including smoking and exposure to 8 categories of adverse childhood experiences (emotional, physical, and sexual abuse; a battered mother; parental separation or divorce; and growing up with a substance-abusing, mentally ill, or incarcerated household member), conducted from August to November 1995 and January to March 1996. SETTING: A primary care clinic for adult members of a large health maintenance organization in San Diego, Calif. PARTICIPANTS: A total of 9215 adults (4958 women and 4257 men with mean [SD] ages of 55.3 [15.7] and 58.1 [14.5] years, respectively) who responded to a survey questionnaire, which was mailed to all patients 1 week after a clinic visit. MAIN OUTCOME MEASURES: Smoking initiation by age 14 years or after age 18 years, and status as ever, current, or heavy smoker. RESULTS: At least 1 of 8 categories of adverse childhood experiences was reported by 63% of respondents. After adjusting for age, sex, race, and education, each category showed an increased risk for each smoking behavior, and these risks were comparable for each category of adverse childhood experiences. Compared with those reporting no adverse childhood experiences, persons reporting 5 or more categories had substantially higher risks of early smoking initiation (odds ratio [OR], 5.4; 95% confidence interval [CI], 4.1-7.1), ever smoking (OR, 3.1; 95% CI, 2.6-3.8), current smoking (OR, 2.1; 95% CI, 1.6-2.7), and heavy smoking (OR, 2.8; 95% CI, 1.9-4.2). Each relationship between smoking behavior and the number of adverse childhood experiences was strong and graded (P<.001). For any given number of adverse childhood experiences, recent problems with depressed affect were more common among smokers than among nonsmokers. CONCLUSIONS: Smoking was strongly associated with adverse childhood experiences. Primary prevention of adverse childhood experiences and improved treatment of exposed children could reduce smoking among both adolescents and adults.

Unintended pregnancy among adult women exposed to abuse or household dysfunction during their childhood.

CONTEXT: Studies have identified childhood sexual and physical abuse as a risk factor for adolescent pregnancy but the relationship between exposure to childhood abuse and unintended pregnancy in adulthood has, to our knowledge, not been studied. OBJECTIVE: To assess whether unintended pregnancy during adulthood is associated with exposure to psychological, physical, or sexual abuse or household dysfunction during childhood. DESIGN AND SETTING: Analysis of data from the Adverse Childhood Experiences Study, a survey mailed to members of a large health maintenance organization who visited a clinic in San Diego, Calif, between August and November 1995 and January and March 1996. The survey had a 63.4% response rate among the target population for this study. PARTICIPANTS: A total of 1193 women aged 20 to 50 years whose first pregnancy occurred at or after age 20 years. MAIN OUTCOME MEASURE: Risk of unintended first pregnancy by type of abuse (psychological, physical, or sexual abuse; peer sexual assault) and type of household dysfunction (physical abuse of mother by her partner, substance abuse by a household member, mental illness of a household member). RESULTS: More than 45% of the women reported that their first pregnancy was unintended, and 65.8% reported exposure to 2 or more types of childhood abuse or household dysfunction. After adjustment for confounders (marital status at first pregnancy and age at first pregnancy), the strongest associations between childhood experiences and unintended first pregnancy included frequent psychological abuse (risk ratio [RR], 1.4; 95% confidence interval [CI], 1.2-1.6), frequent physical abuse of the mother by her partner (RR, 1.4; 95% CI, 1.1-1.7), and frequent physical abuse (RR, 1.5; 95% CI, 1.2-1.8). Women who experienced 4 or more types of abuse during their childhood were 1.5 times (95% CI, 1.2-1.8) more likely to have an unintended first pregnancy during adulthood than women who did not experience any abuse. CONCLUSIONS: This study indicates that there may be a dose-response association between exposure to childhood abuse or household dysfunction and unintended first pregnancy in adulthood. Additional research is needed to fully understand the causal pathway of this association.

Heart failure survival among older adults in the United States: a poor prognosis for an emerging epidemic in the Medicare population.

OBJECTIVE: To describe the 6-year probability of survival for older adults after their first hospitalization for heart failure. SETTING: National Medicare hospital claims records for 1984 through 1986 and Medicare enrollment records from 1986 through 1992. DESIGN: We identified a national cohort of 170 239 (9% black patients) Medicare patients, 67 years or older, with no evidence of heart failure in 1984 or 1985, who were hospitalized and discharged for the first time in 1986 with a principal diagnosis of heart failure. For groups defined by race, sex, age, Medicaid eligibility, and comorbid conditions, we compared the probability of survival with Cox proportional hazards regression. RESULTS: Only 19% of black men, 16% of white men, 25% of black women, and 23% of white women survived 6 years. One third died within the first year. Men had lower median survival and 38% greater risk of mortality than did women (P<.05). White men had 10% greater risk of mortality than did black men (P<.05). Medicaid eligibility (white adults only) and diabetes were associated with increased mortality (P<.05). CONCLUSIONS: The prognosis for older adults with heart failure underscores the importance of prevention strategies and early detection and treatment modalities that can prevent, improve, or reverse myocardial dysfunction, particularly for the growing number of adults who are at increased risk for developing heart failure because of hypertension, diabetes, or myocardial infarction.

Serum folate and risk for coronary heart disease: results from a cohort of US adults.

PURPOSE: To assess the role of serum folate in the risk for coronary heart disease in a national cohort of US adults. METHODS: Data from the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study (N = 1921) were used to determine whether a low serum folate concentration was associated with an increased risk for incident coronary heart disease (N = 284). The Cox proportional hazards model adjusted for age, sex, race, education, serum cholesterol, systolic blood pressure, body mass index, cigarette smoking, and alcohol consumption. RESULTS: The association between folate and risk for coronary heart disease differed by age group (p = 0.03). Among persons aged 35-55 years, the relative risk for heart disease was 2.4 (95% confidence interval (CI), 1.1-5.2) for persons in the lowest quartile (< or = 9.9 nmol/L) when compared with those in the highest quartile (> or = 21.8 nmol/L). However, among persons > or = 55 years the relative risk was 0.5 (95% CI, 0.3-0.8) for comparisons of the lowest versus highest quartiles. CONCLUSIONS: If the age differences in the risk for heart disease are confirmed, randomized clinical trials assessing the role of folic acid for the prevention of heart disease may need to include young adults in order to demonstrate benefits related to folate supplementation.

Relationship of childhood abuse and household dysfunction to many of the leading causes of death in adults. The Adverse Childhood Experiences (ACE) Study.

BACKGROUND: The relationship of health risk behavior and disease in adulthood to the breadth of exposure to childhood emotional, physical, or sexual abuse, and household dysfunction during childhood has not previously been described. METHODS: A questionnaire about adverse childhood experiences was mailed to 13,494 adults who had completed a standardized medical evaluation at a large HMO; 9,508 (70.5%) responded. Seven categories of adverse childhood experiences were studied: psychological, physical, or sexual abuse; violence against mother; or living with household members who were substance abusers, mentally ill or suicidal, or ever imprisoned. The number of categories of these adverse childhood experiences was then compared to measures of adult risk behavior, health status, and disease. Logistic regression was used to adjust for effects of demographic factors on the association between the cumulative number of categories of childhood exposures (range: 0-7) and risk factors for the leading causes of death in adult life. RESULTS: More than half of respondents reported at least one, and one-fourth reported > or = 2 categories of childhood exposures. We found a graded relationship between the number of categories of childhood exposure and each of the adult health risk behaviors and diseases that were studied (P < .001). Persons who had experienced four or more categories of childhood exposure, compared to those who had experienced none, had 4- to 12-fold increased health risks for alcoholism, drug abuse, depression, and suicide attempt; a 2- to 4-fold increase in smoking, poor self-rated health, > or = 50 sexual intercourse partners, and sexually transmitted disease; and 1.4- to 1.6-fold increase in physical inactivity and severe obesity. The number of categories of adverse childhood exposures showed a graded relationship to the presence of adult diseases including ischemic heart disease, cancer, chronic lung disease, skeletal fractures, and liver disease. The seven categories of adverse childhood experiences were strongly interrelated and persons with multiple categories of childhood exposure were likely to have multiple health risk factors later in life. CONCLUSIONS: We found a strong graded relationship between the breadth of exposure to abuse or household dysfunction during childhood and multiple risk factors for several of the leading causes of death in adults.

Impact of multiple risk factor profiles on determining cardiovascular disease risk.

BACKGROUND: We examined the association between clustering of risk factors and the risk for coronary heart disease, stroke, and all-cause mortality. METHODS: Data from the First National Health and Nutrition Examination Survey Epidemiologic Follow-Up Study (N = 12,932) were used to estimate the relative risk for coronary heart disease (N = 2,255), stroke (N = 929), and death from any cause (N = 4,506) by the number of cardiovascular disease risk factors present. Risk factors included current smoking, overweight, hypertension, high blood cholesterol, and diabetes. RESULTS: The proportions of respondents with 0, 1, 2, 3, or > or = 4 risk factors were 25.0, 32.8, 27.8, 12.3, and 2.1%, respectively. Relative risks for coronary heart disease associated with having 1, 2, 3, and > or = 4 risk factors were 1.6 (95% confidence interval [CI] 1.4, 1.9), 2.2 (95% CI 1.9, 2.6), 3.1 (95% CI 2.6, 3.6), and 5.0 (95% CI 3.9, 6.3), respectively. Relative risks for stroke associated with the same risk levels were 1.4 (95% CI 1.1, 1.8), 1.9 (95% CI 1.5, 2.4), 2.3 (95% CI 1.7, 3.0), and 4.3 (95% CI 3.0, 6.3), respectively. Similar results were observed for all-cause mortality. CONCLUSIONS: Risk for cardiovascular disease and all-cause mortality increased substantially with each additional risk factor. This supports the continued need for primary prevention of cardiovascular disease risk factors.

Pharmacologic management of heart failure among older adults by office-based physicians in the United States.

BACKGROUND: Despite the recent availability of new classes of heart failure medications, little is known about national patterns in the actual physician utilization of these drugs. METHODS: In the National Ambulatory Medical Care Survey, 2912 US physicians reported on 16,968 office visits in 1991-1992 with patients aged > or = 65 years. National estimates were obtained from weighted results that accounted for the complex sampling design. RESULTS: An estimated 8.3 million (2.6%) office visits with older adults involved heart failure. This included 9.3% of visits to cardiologists, 4.3% to internists, 3.5% to general and family physicians, and 0.6% to other physicians. The most frequently prescribed medications during visits with these patients were diuretics (69%), digitalis compounds (46%), angiotensin-converting enzyme inhibitors (30%), and nitrates (19%). Internists and general and family physicians prescribed angiotensin-converting enzyme inhibitors, digitalis compounds, and loop diuretics for patients with heart failure less often than did cardiologists. CONCLUSIONS: These are the first national surveillance estimates of physician practices in the management of heart failure. These data were collected during the same period in which heart failure clinical trial results were initially published, and they provide a baseline for monitoring the influence of recent clinical practice guidelines and professional education on changes in the management of heart failure by primary care physicians.

Socioeconomic status, race, and death from coronary heart disease.

INTRODUCTION: Data to assess factors associated with differences in coronary heart disease mortality between Caucasians and African Americans are limited. We assessed risks for sudden, nonsudden, and other coronary death between Caucasians and African Americans in relation to known risk factors for coronary disease and socioeconomic status. METHODS: We analyzed data from the 1986 National Mortality Followback Survey, the 1985 National Health Interview Survey, and the U.S. Bureau of the Census. Logistic regression methods were used to create multivariate models to assess the relationship of socioeconomic status and other known modifiable risk factors to death from each of the three coronary diseases for Caucasians and African Americans separately. RESULTS: In an age- and gender-adjusted analysis of data on men 25-44 years old and women 25-54 years old, African Americans had about twice the risk for sudden, nonsudden, or other coronary death as did Caucasians. Adjusted risks for coronary death for Caucasians associated with modifiable risk factors (cigarette smoking, body weight, diabetes, and hypertension) either resembled or were slightly greater than those for African Americans. Half or more of all excess risks for African Americans in multivariate models could be explained by socioeconomic status. About 18% of excess sudden coronary death risk could be further explained by known modifiable coronary heart disease risk factors. CONCLUSIONS: Broad public health efforts are needed to address these causes of excess mortality.

National trends in the initial hospitalization for heart failure.

OBJECTIVES: Heart failure is a major health care burden among older adults, but information on recent trends has not been available. We compare rates, sociodemographic characteristics, and discharge outcomes of the initial hospitalization for heart failure in the Medicare populations of 1986 and 1993. DESIGN: Information reported on the Medicare hospital claims record during initial hospitalization for heart failure was compared for patients aged 65 and older hospitalized in 1986 (N = 631,306) and those aged 65 and older hospitalized in 1993 (N = 803,506). RESULTS: Age-standardized hospitalization rates (per 1000 person-years) for any diagnosis of heart failure were higher in 1993 than in 1986 (white: 24.6 vs 22.4, black: 26.1 vs 22.4, respectively). Age-specific results suggested an earlier onset of heart failure in black adults. In 1993, compared with 1986, higher proportions of heart failure patients were discharged to another care facility (white: 23.9% vs 16.8%, black: 17.6% vs 10.5%, respectively) or to health service care at home (white: 11.3% vs 6.0%, black: 12.4% vs 6.5%, respectively). In contrast, in-hospital mortality was lower in 1993 than in 1986 (white: 10.4% vs 13.3%, black: 8.9% vs 11.1%, respectively). CONCLUSION: The increased numbers of hospitalizations for heart failure and the likelihood that these patients will require advanced nursing care after discharge have important implications for future national health care expenditures and resources.

Leisure-time physical activity among older adults. United States, 1990.

OBJECTIVE: To investigate the prevalence and selected correlates of leisure-time physical activity in a nationally representative sample of persons aged 65 years or older. METHODS: Data from 2783 older male and 5018 older female respondents to the 1990 National Health Interview Survey were used. Regular physical activity was defined as participation in leisure-time physical activities 3 times or more per week for 30 minutes or more during the previous 2 weeks. Odds ratios (ORs) were estimated from multivariate logistic regression analysis. RESULTS: Prevalence of regular physical activity was 37% among older men and 24% among older women. Correlates of regular physical activity included the perception of excellent to good health (men: OR, 1.5; 95% confidence interval [CI], 1.1-1.9; women: OR, 1.6; 95% CI, 1.3-1.9), correct exercise knowledge (men: OR, 2.4; 95% CI, 1.9-3.1; women: OR, 2.7; 95% CI, 2.2-3.4), no activity limitations (men: OR, 1.3; 95% CI, 1.0-1.6; women: OR, 1.7; 95% CI, 1.4-2.0) and not perceiving "a lot" of stress during the previous 2 weeks (men: OR, 1.7; 95% CI, 1.2-2.4; women: OR, 1.3; 95% CI, 1.0-1.6). Among those who had been told at least twice that they had high blood pressure, physician's advice to exercise was associated with regular physical activity (men: OR, 1.6; 95% CI, 1.2-2.3; women: OR, 1.5; 95% CI, 1.2-1.9). The 2 major activities among active older adults were walking (men, 69%; women, 75%) and gardening (men, 45%; women, 35%). CONCLUSIONS: Prevalence of regular physical activity is low among older Americans. Identifying the correlates of physical activity will help to formulate strategies to increase physical activity in this age group.

Evaluation of smoking on the physical activity and depressive symptoms relationship.

Physical activity is inversely associated with depressive symptoms, and cigarette smoking is positively associated with depressive symptoms. Data from the first National Health and Nutrition Examination Survey (NHANES I) and the NHANES I Epidemiologic Follow-up study were analyzed to determine whether the relationship between physical activity and self-reported distress (depressive symptoms as measured by the Center for Epidemiologic Studies Depression Scale) was different for cigarette smokers and nonsmokers. Logistic regression was used to calculate odds ratios (adjusted for age, race, sex, education, alcohol use, and perceived health status) for depressive symptoms (> or = 16) associated with physical activity and smoking status among 2,054 respondents. At baseline, the odds ratio for depressive symptoms was about 2 times higher for moderately active smokers and nonsmokers, and 3 times higher for low active smokers and nonsmokers, compared with highly active nonsmokers. For 1,132 persons with a low number of depressive symptoms (< 16) at baseline, the incidence of depressive symptoms after 7-9 yr of follow-up was about 2 times higher for low/moderately active smokers and nonsmokers than for highly active nonsmokers. The association between physical activity and the prevalence and incidence of depressive symptoms is not significantly modified by smoking status.

Depression and smoking initiation among US Latinos.

We assessed the relationship between depression and smoking initiation among people of Mexican, Puerto Rican and Cuban ancestry residing in specific geographic areas of the United States. Survey data were examined to calculate incidence of smoking initiation and prevalences and odds ratios for ever smoking by presence of depressed mood, a history of major depression or both conditions. Depressed mood, a history of major depression or both conditions were associated with smoking initiation risks during childhood, adolescence and young adulthood. These findings suggest that the relationship between depressive states and smoking initiation is established early in life. More definitive studies are needed to confirm these findings.

Serum folate and risk for ischemic stroke. First National Health and Nutrition Examination Survey epidemiologic follow-up study.

BACKGROUND AND PURPOSE: A serum folate concentration < or = 9.2 nmol/L has been associated with elevated levels of plasma homocyst(e)ine. Elevated homocyst(e)ine levels have been associated with ischemic stroke in case-control studies; however, the results from prospective studies have been equivocal. We investigated whether a folate concentration < or = 9.2 nmol/L was associated with ischemic stroke in a national cohort. METHODS: We used data from the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study (n = 2006). Cox proportional hazards analyses were used to adjust for differences in follow-up time and covariates. During the 13-year follow-up, 98 ischemic strokes occurred. RESULTS: After adjusting for age, race, sex, education, diabetes, history of heart disease, systolic blood pressure, body mass index, hemoglobin level, cigarette smoking, and alcohol intake, participants with a folate concentration < or = 9.2 nmol/L were at slightly increased risk for ischemic stroke (relative risk [RR], 1.37; 95% confidence interval [CI], 0.82 to 2.29). There was a folate-race interaction (P = .11 for interaction term). Whites with a folate concentration < or = 9.2 nmol/L had a relative risk of 1.18 (95% CI, 0.67 to 2.08), whereas blacks had a relative risk of 3.60 (95% CI, 1.02 to 12.71). CONCLUSIONS: These findings suggest that a folate concentration < or = 9.2 nmol/L may be a risk factor for ischemic stroke, especially in blacks. However, given the small number of stroke events, additional studies are needed to assess the role of folate in the epidemiology of ischemic stroke.
