The validity of self-reports of past body weights by U.S. adults.

Past weight or patterns of weight change may be more important to chronic disease risk than current weight. Self-reports, however, are often the only source of information about past body weight. To date, very few studies have examined factors affecting the validity of self-reported past body weight. We examined the validity of self-reported past body weights of 1,931 U.S. adults who were participants in the First National Health and Nutrition Examination Survey (1971–1975) and were interviewed again in the National Health and Nutrition Examination Survey I Epidemiologic Follow-up Study (1982–1984). We compared the body weight measured during the initial examination (1971–1975) with the recalled 1971–1975 body weight reported during the follow-up interview (1982–1984). Recalled past weight was strongly correlated with previously measured weight (r = 0.73 for men, and r = 0.74 for women). Men overestimated their past body weight, whereas women underestimated their past weight. Although 39% of men and 41% of women estimated their past weight within 5 pounds, approximately 17% of women and 10% of men underestimated their past weight more than 15 pounds. Accuracy of reporting was influenced by sex, race, current body mass index, and the amount of weight gained over the 10 years following the initial examination. These factors should be considered when using recalled weight in epidemiologic studies.

Relationships between hours of sleep and health-risk behaviors in US adolescent students

OBJECTIVE To examine associations between insufficient sleep (<8h on average school nights) and health-risk behaviors. METHODS 2007 national Youth Risk Behavior Survey data of U.S. high school students (n=12,154) were analyzed. Associations were examined on weighted data using multivariate logistic regression. RESULTS Insufficient sleep on an average school night was reported by 68.9% of students. Insufficient sleep was associated with higher odds of current use of cigarettes (age-adjusted odds ratio [AOR], 1.67; 95% confidence interval [CI], 1.45-1.93), marijuana (AOR, 1.52; 95% CI, 1.31-1.76), and alcohol (AOR, 1.64; 95% CI, 1.46-1.84); current sexual activity (AOR, 1.41; 95% CI, 1.25-1.59); seriously considered attempting suicide (AOR, 1.86; 95% CI, 1.60-2.16); feeling sad or hopeless (AOR, 1.62; 95% CI, 1.43-1.84); physical fighting (AOR, 1.40; 95% CI, 1.24-1.60), not being physically active at least 60min ≥ 5days in the past 7days (AOR, 1.16; 95% CI, 1.04-1.29), using the computer ≥3h/day (AOR, 1.58; 95% CI, 1.38-1.80), and drinking soda/pop > 1time/day (AOR, 1.14; 95% CI, 1.03-1.28). CONCLUSION Two-thirds of adolescent students reported insufficient sleep, which was associated with many health-risk behaviors. Greater awareness of the impact of sleep insufficiency is vital.

The Relationship of Level of Positive Mental Health With Current Mental Disorders in Predicting Suicidal Behavior and Academic Impairment in College Students

Abstract Objective: To investigate whether level of positive mental health complements mental illness in predicting students at risk for suicidal behavior and impaired academic performance. Participants: A sample of 5,689 college students participated in the 2007 Healthy Minds Study and completed an Internet survey that included the Mental Health Continuum–Short Form and the Patient Health Questionnaire screening scales for depression and anxiety disorders, questions about suicide ideation, plans, and attempts, and academic impairment. Results: Just under half (49.3%) of students were flourishing and did not screen positive for a mental disorder. Among students who did, and those who did not, screen for a mental disorder, suicidal behavior and impaired academic performance were lowest in those with flourishing, higher among those with moderate, and highest in those with languishing mental health. Conclusions: Positive mental health complements mental disorder screening in mental health surveillance and prediction of suicidal behavior and impairment of academic performance.

Prevalence of insufficient, borderline, and optimal hours of sleep among high school students - United States, 2007.

We describe the prevalence of insufficient, borderline, and optimal sleep hours among U.S. high school students on an average school night. Most students (68.9%) reported insufficient sleep, whereas few (7.6%) reported optimal sleep. The prevalence of insufficient sleep was highest among female and black students, and students in grades 11 and 12.

The relationship of adverse childhood experiences to a history of premature death of family members

BackgroundTo assess the association between adverse childhood experiences (ACEs), including childhood abuse and neglect, and serious household dysfunction, and premature death of a family member. Because ACEs increase the risk for many of the leading causes of death in adults and tend to be familial and intergenerational, we hypothesized that persons who report having more ACEs would be more likely to have family members at risk of premature death.MethodsWe used data from 17,337 adult health plan members who completed a survey about 10 types of ACEs and whether a family member died before age 65. The prevalence of family member premature death and its association with ACEs were assessed.ResultsFamily members of respondents who experienced any type of ACEs were more likely to have elevated prevalence for premature death relative to those of respondents without such experience (p < 0.01). The highest risk occurred among those who reported having been physically neglected and living with substance abusing or criminal family members during childhood. A powerful graded relationship between the number of ACEs and premature mortality in the family was observed for all age groups, and comparison between groups reporting 0 ACE and ≥ 4 ACEs yielded an OR of 1.8 (95%CI, 1.6–2.0).ConclusionAdverse childhood experiences may be an indicator of a chaotic family environment that results in an increased risk of premature death among family members.

Time Trends in Therapies and Outcomes for Adult Inflammatory Bowel Disease, Northern California, 1998–2005

BACKGROUND & AIMS The management of inflammatory bowel disease (IBD) has become increasingly complicated, and it is unknown whether poor outcomes (prolonged steroid use, hospitalizations, and surgery) have declined in the general population. METHODS This multilevel study used computerized clinical data. The study comprised 2892 adults with Crohns disease (CD) and 5895 with ulcerative colitis (UC) who received care at 16 medical centers within an integrated care organization in Northern California between 1998 and 2005. RESULTS Time trends included (1) a shift in gastroenterology-related visits from the gastroenterology division to primary care; (2) increased use of IBD-related drugs, except for a 7% decline in use of 5-aminosalicylate in CD and no change in steroid use for CD; (3) for the prevalence of prolonged steroid exposure (120 days of continuous use), a 36% decline for CD with a 27% increase for UC; (4) declines in the hospitalization rates of 33% for CD and 29% for UC; and (5) for the surgery rate, no significant change for CD with a 50% decline for UC. CONCLUSIONS Declines in prolonged steroid exposure and the hospitalization rate for CD and in the hospitalization and surgery rate for UC are encouraging; however, the increase in prolonged steroid exposure for UC merits concern and further investigation. The variability in care patterns observed in this study suggests lack of standardization of care and the opportunity to identify targets for quality improvement. These findings should stimulate research to quantify the effect of current trends in IBD management.

Incidence, prevalence, and time trends of pediatric inflammatory bowel disease in Northern California, 1996 to 2006.

OBJECTIVE To examine the incidence and prevalence of pediatric inflammatory bowel disease (IBD) during 1996-2006 in a community-based health-care delivery system. STUDY DESIGN Members of Kaiser Permanente Northern California aged 0 to 17 years with IBD were identified by use of computerized medical information with confirmation obtained through review of the medical record. RESULTS The average annual incidence of IBD per 100000 was 2.7 (95% confidence interval [CI], 2.3-3.1) for Crohns disease (CD) and 3.2 (CI, 2.8-3.6) for ulcerative colitis (UC). During the 11-year study period, the annual incidence per 100000 increased from 2.2 to 4.3 for CD (P = .09) and from 1.8 to 4.9 for UC (P < .001). The ratio of incident CD cases to incident UC cases was 0.9 in non-Hispanic whites, 1.6 in African Americans (P = .12), 0.3 in Hispanics (P < .001) and 0.4 in Asians (P = .04). The average length of enrollment during the 11-year study period exceeded 8 years. The point prevalence on December 31, 2006, per 100000 was 12.0 for CD (CI, 9.6-14.4) and 19.5 (CI, 16.5-22.6) for UC. CONCLUSIONS In this population the incidence of UC increased significantly by 2.7-fold and CD increased 2.0-fold without reaching statistical significance. Hispanic and Asian children had development of UC more often than CD, suggesting possible etiologic differences across racial and ethnic groups.

Association between perceived insufficient sleep, frequent mental distress, obesity and chronic diseases among US adults, 2009 behavioral risk factor surveillance system.

BackgroundAlthough evidence suggests that poor sleep is associated with chronic disease, little research has been conducted to assess the relationships between insufficient sleep, frequent mental distress (FMD ≥14 days during the past 30 days), obesity, and chronic disease including diabetes mellitus, coronary heart disease, stroke, high blood pressure, asthma, and arthritis.MethodsData from 375,653 US adults aged ≥ 18 years in the 2009 Behavioral Risk Factor Surveillance System were used to assess the relationships between insufficient sleep and chronic disease. The relationships were further examined using a multivariate logistic regression model after controlling for age, sex, race/ethnicity, education, and potential mediators (FMD and obesity).ResultsThe overall prevalence of insufficient sleep during the past 30 days was 10.4% for all 30 days, 17.0% for 14–29 days, 42.0% for 1–13 days, and 30.6% for zero day. The positive relationships between insufficient sleep and each of the six chronic disease were significant (p < 0.0001) after adjustment for covariates and were modestly attenuated but not fully explained by FMD. The relationships between insufficient sleep and both diabetes and high blood pressure were also modestly attenuated but not fully explained by obesity.ConclusionsAssessment of sleep quantity and quality and additional efforts to encourage optimal sleep and sleep health should be considered in routine medical examinations. Ongoing research designed to test treatments for obesity, mental distress, or various chronic diseases should also consider assessing the impact of these treatments on sleep health.

Adverse childhood experiences and sleep disturbances in adults

BACKGROUND Sleep disturbances are associated with an increased risk for many chronic diseases and unhealthy behaviors. A history of adverse childhood experiences (ACEs) is also associated with similar adult health outcomes. We studied the relationship between multiple ACEs and the likelihood of experiencing self-reported sleep disturbances in adulthood. METHODS We used data from the adverse childhood experiences (ACE) study, a retrospective cohort study of 17,337 adult health maintenance organization members in California who completed a survey about eight ACEs, which included childhood abuse and growing up with various forms of household dysfunction. The self-reported sleep disturbances measured included ever having trouble falling or staying asleep and feeling tired after a good nights sleep. We used an integer count of the number of ACEs (the ACE score) to assess the cumulative impact of these experiences on the likelihood of self-reported sleep disturbances. RESULTS Thirty-three percent of the cohort reported trouble falling or staying asleep, while 24% reported feeling tired after sleeping. All eight ACE categories were associated with an increased likelihood of self-reported sleep disturbances (p<0.05). Compared to persons with an ACE score of 0, those with an ACE score ≥ 5 were 2.1 (95% CI: 1.8-2.4) times more likely to report trouble falling or staying asleep and 2.0 (95% CI: 1.7-2.3) times more likely to report feeling tired even after a good nights sleep. The trend for increasing odds for both types of self-reported sleep disturbance with increasing ACE scores was statistically significant (p<0.0001). CONCLUSIONS Adverse childhood experiences were associated with self-reported sleep disturbances in adulthood, and the ACE score had a graded relationship to these sleep disturbances. A history of ACEs should be obtained for patients with self-reported sleep disturbances to coordinate services that ameliorate the long-term effects of these events.

Sleep disordered breathing and depression among U.S. adults: National Health and Nutrition Examination Survey, 2005-2008.

STUDY OBJECTIVE To determine if symptoms of sleep disordered breathing (SDB) are associated with depression symptomology in a national sample. DESIGN National Health and Nutrition Examination Survey. SETTING U.S., 2005-2008. PARTICIPANTS 9,714 adults (≥ 18 years). MEASUREMENTS Respondents were asked about frequency of snoring and snorting, gasping, or stopping breathing while asleep and completed the PHQ-9 (a 9-item depression screener). Odds ratios (OR) and 95% confidence intervals (CI) for SDB symptom-associated probable major depression (defined as a PHQ-9 score ≥ 10) were obtained from sex-specific logistic regression analyses adjusted for body mass index, age, race/ethnicity, and education. RESULTS Among men, 6.0% reported physician-diagnosed sleep apnea, 37.2% snored ≥ 5 nights/week, 7.1% snorted/stopped breathing ≥ 5 nights/week, and 5.0% had PHQ-9 scores ≥ 10. Among women, 3.1% reported sleep apnea, 22.4% snored ≥ 5 nights/week, 4.3% snorted/stopped breathing ≥ 5 nights/week, and 8.4% had PHQ-9 scores ≥ 10. Sleep apnea was associated with probable major depression (OR = 2.4; 95% CI: 1.5, 3.6 among men; OR = 5.2; 95% CI: 2.7, 9.9 among women). Snoring was not associated with depression symptoms in men or women. Snorting/stopping breathing ≥ 5 nights/week compared to never was strongly associated with probable major depression in men (OR = 3.1; 95% CI: 1.8, 5.2) and women (OR = 3.0; 95% CI: 1.6, 5.4). CONCLUSION Frequent snorting/stopping breathing was associated with probable major depression by the PHQ-9 in a national sample of adults. Additional research may be needed to determine whether regular screening for these conditions by mental health professionals and sleep specialists should be recommended.
