RESUMO

INTRODUCTION: Childhood declines in cardiovascular health have been linked to the development of subclinical atherosclerosis; however, less is known about the timing and sequence of the decline of the specific cardiovascular health components. The study objective is to identify the patterns of decline and associations with adulthood subclinical atherosclerosis. METHODS: Data were pooled from 5 cardiovascular cohorts. Clinical components of cardiovascular health (BMI, blood pressure, cholesterol, and blood glucose) were categorized as ideal or nonideal using American Heart Association definitions. Multitrajectory models simultaneously fitted the probability ideal for each factor. Adjusted associations between trajectory groups and carotid intima-media thickness were modeled. Data were pooled from December 1, 2015 to June 1, 2019; statistical analysis occurred between June 1, 2019 and June 1, 2020. RESULTS: This study included 9,388 individuals (55% female, 66% White). A total of 5 distinct trajectory groups were created: 1 maintained the ideal levels of all the 4 health factors, 2 had risk onset of a single factor in childhood, 1 had risk onset of multiple factors in childhood, and 1 had risk onset in adulthood. Those with childhood multiple risk onset had 8.1% higher carotid intima-media thickness (95% CI=0.067, 0.095) than those in the ideal group, childhood cholesterol risk onset had 5.9% higher carotid intima-media thickness (95% CI=0.045, 0.072), childhood BMI risk onset had 5.5% higher carotid intima-media thickness (95% CI=0.041, 0.069), and early adulthood multiple risk onset had 2.7% higher carotid intima-media thickness (95% CI=0.013, 0.041). CONCLUSIONS: Those who lost the ideal status of cardiovascular health in childhood and early adulthood had more subclinical atherosclerosis than those who retained the ideal cardiovascular health across the life course, underscoring the importance of preserving the ideal cardiovascular health beginning in childhood and continued into adulthood.

RESUMO

The prevalence of ideal cardiovascular health (CVH) among adults in the United States is low and decreases with age. Our objective was to identify specific age windows when the loss of CVH accelerates, to ascertain preventive opportunities for intervention. Data were pooled from 5 longitudinal cohorts (Project Heartbeat!, Cardiovascular Risk in Young Finns Study, The Bogalusa Heart Study, Coronary Artery Risk Development in Young Adults, Special Turku Coronary Risk Factor Intervention Project) from the United States and Finland from 1973 to 2012. Individuals with clinical CVH factors (i.e., body mass index, blood pressure, cholesterol, blood glucose) measured from ages 8 to 55 years were included. These factors were categorized and summed into a clinical CVH score ranging from 0 (worst) to 8 (best). Adjusted, segmented, linear mixed models were used to estimate the change in CVH over time. Among the 18,343 participants, 9,461 (52%) were female and 12,346 (67%) were White. The baseline mean (standard deviation) clinical CVH score was 6.9 (1.2) at an average age of 17.6 (8.1) years. Two inflection points were estimated: at 16.9 years (95% confidence interval: 16.4, 17.4) and at 37.2 years (95% confidence interval: 32.4, 41.9). Late adolescence and early middle age appear to be influential periods during which the loss of CVH accelerates.

RESUMO

Importance: Cross-sectional measures of cardiovascular health (CVH) have been associated with cardiovascular disease in older age, but little is known about longitudinal trajectories in CVH and their association with subclinical atherosclerosis in middle age. Objectives: To model long-term patterns in CVH starting in childhood and to assess their association with subclinical atherosclerosis in middle age. Design, Setting, and Participants: This cohort study used data from 5 prospective cardiovascular cohort studies from the United States and Finland from 1973 to 2015. A total of 9388 participants aged 8 to 55 years had at least 3 examinations and were eligible for this study. Statistical analysis was performed from December 1, 2015, to June 1, 2019. Exposures: Clinical CVH factors (body mass index, total cholesterol level, blood pressure, and glucose level) were classified as ideal, intermediate, or poor, and were summed as a clinical CVH score. Group-based latent class modeling identified trajectories in this score over time. Main Outcomes and Measures: Carotid intima-media thickness (cIMT) was measured for participants in 3 cohorts, and high cIMT was defined as a value at or above the 90th percentile. The association between CVH trajectory and cIMT was modeled using both linear and logistic regression adjusted for demographics, baseline health behaviors, and baseline (or proximal) CVH score. Results: Among 9388 participants (5146 [55%] female; 6228 [66%] white; baseline mean [SD] age, 17.5 [7.5] years), 5 distinct trajectory groups were identified: high-late decline (1518 participants [16%]), high-moderate decline (2403 [26%]), high-early decline (3066 [32%]), intermediate-late decline (1475 [16%]), and intermediate-early decline (926 [10%]). The high-late decline group had significantly lower adjusted cIMT vs other trajectory groups (high-late decline: 0.64 mm [95% CI, 0.63-0.65 mm] vs intermediate-early decline: 0.72 mm [95% CI, 0.69-0.75 mm] when adjusted for demographics and baseline smoking, diet, and physical activity; P < .01). The intermediate-early declining group had higher odds of high cIMT (odds ratio, 2.4; 95% CI, 1.3-4.5) compared with the high-late decline group, even after adjustment for baseline or proximal CVH score. Conclusions and Relevance: In this study, CVH declined from childhood into adulthood. Promoting and preserving ideal CVH from early life onward may be associated with reduced CVD risk later in life.

RESUMO

AIMS: To evaluate several adult diabetes risk calculation tools for predicting the development of incident diabetes and pre-diabetes in a bi-racial, young adult population. METHODS: Surveys beginning in young adulthood (baseline age ≥18) and continuing across multiple decades for 2122 participants of the Bogalusa Heart Study were used to test the associations of five well-known adult diabetes risk scores with incident diabetes and pre-diabetes using separate Cox models for each risk score. Racial differences were tested within each model. Predictive utility and discrimination were determined for each risk score using the Net Reclassification Index (NRI) and Harrell's c-statistic. RESULTS: All risk scores were strongly associated (p<.0001) with incident diabetes and pre-diabetes. The Wilson model indicated greater risk of diabetes for blacks versus whites with equivalent risk scores (HR=1.59; 95% CI 1.11-2.28; p=.01). C-statistics for the diabetes risk models ranged from 0.79 to 0.83. Non-event NRIs indicated high specificity (non-event NRIs: 76%-88%), but poor sensitivity (event NRIs: -23% to -3%). CONCLUSIONS: Five diabetes risk scores established in middle-aged, racially homogenous adult populations are generally applicable to younger adults with good specificity but poor sensitivity. The addition of race to these models did not result in greater predictive capabilities. A more sensitive risk score to predict diabetes in younger adults is needed.

RESUMO

BACKGROUND: Hand tremor and blood pressure (BP) are both increased by adrenergic stimulation and reduced by ß-blockade, indicating that they may share a common underlying pathophysiology. METHODS: We prospectively examined the relationship between postural hand tremor and incident hypertension in a community-based cohort of 715 (184 blacks and 531 whites) adults without hypertension and not using medications to control tremor (e.g. ß-blockers). At baseline, tremor was measured with participants holding a laser pointer aimed at a sheet of Polaroid film 8 feet away with arm outstretched for 8 s in a darkened room, and characterized by the width of the circle diameter encompassing all exposures and enumeration of exposure dots in the same area. Incident hypertension was defined as new elevation of BP (SBP ≥ 140 or DBP ≥ 90 mmHg, based on an average of six readings over two visits) or antihypertensive medication use. RESULTS: During a median follow-up of 6.4 years, 198 (69 blacks and 129 whites) participants developed hypertension. Tremor measurements (by quartile) were positively associated with incident hypertension after adjustment for baseline demographics, lifestyle characteristics, and BP. There was significant interaction by race (P = 0.01). Among whites, tremor was positively associated with incident hypertension [hazard ratio highest vs. lowest quartile: 2.50 (95% confidence interval: 1.40-4.48) dot method and 3.24 (1.78-5.90) circular method; both P trend <0.01]. Among blacks, tremor was not associated with hypertension. CONCLUSION: In this community-based cohort, postural hand tremor was strongly associated with the risk of incident hypertension among whites and merits further study as a potential indicator of risk for hypertension.

RESUMO

BACKGROUND: Pediatric Candida infections are associated with worse clinical outcomes and increased costs. Yet, it is not definitively known if particular species are associated with more severe illness. Differential risk factor exposures among the species group may also exist. We aimed to determine whether certain Candida species are more strongly associated with worse outcomes, and whether certain risk factors more strongly predispose patients to infection with certain species. METHODS: Microbiology lab records from patients seen from 2003 to 2010 at an urban children's hospital were reviewed for invasive or disseminated Candida infections. Data on measures of disease severity/outcome and risk factors were abstracted and analyzed to determine differences associated with various Candida species. RESULTS: Exactly 106 cases of infection were analyzed. Non-albicans species were associated with a significantly longer length of stay postdiagnosis (P=0.03), as well as longer treatment (P=0.02). Candida albicans was associated with a higher number of antihypotensive medications required (P=0.03) and length of mechanical ventilation postdiagnosis (P=0.05). Candida tropicalis was associated with the highest mortality (45.5%). Hypotension, which was found to be significantly associated with concurrent infection, was significantly associated with increased risk of mortality (odds ratio =5.85, P=0.005). Initial choice of antifungal therapy was not associated with differences in eventual patient mortality. Multivariate logistic regression modeling revealed a trend toward C. albicans infection in patients receiving antineoplastic chemotherapy and non-albicans infection in patients with >96 hours mechanical ventilation. CONCLUSION: Interspecies differences may exist for Candida in terms of disease severity and risk factors. Underlying morbidity and the role of concurrent infections may play a key role in poor outcomes.

RESUMO

The patient-centered medical home model of primary care has received considerable attention for its potential to improve outcomes and reduce health care costs. Yet little information exists about the model's ability to achieve these goals for Medicaid patients. We sought to evaluate the effect of patient-centered medical home certification of Louisiana primary care clinics on the quality and cost of care over time for a Medicaid population. We used a quasi-experimental pre-post design with a matched control group to assess the effect of medical home certification on outcomes. We found no impact on acute care use and modest support for reduced costs and primary care use among medical homes serving higher proportions of chronically ill patients. These findings provide preliminary results related to the ability of the patient-centered medical home model to improve outcomes for Medicaid beneficiaries. The findings support a case-mix-adjusted payment policy for medical homes going forward.

RESUMO

BACKGROUND: Pharmacy refill adherence assesses the medication-filling behaviors, whereas self-report adherence assesses the medication-taking behaviors. We contrasted the association of pharmacy refill and self-reported antihypertensive medication adherence with blood pressure (BP) control and cardiovascular disease (CVD) incidence. METHODS AND RESULTS: Adults (n = 2075) from the prospective Cohort Study of Medication Adherence among Older Adults recruited between August 2006 and September 2007 were included. Antihypertensive medication adherence was determined using a pharmacy refill measure, medication possession ratio (MPR; low, medium, and high MPR: <0.5, 0.5 to <0.8, and ≥0.8, respectively) and a self-reported measure, eight-item Morisky Medication Adherence Scale (MMAS-8; low, medium, and high MMAS-8: <6, 6 to <8, and 8, respectively). Incident CVD events (stroke, myocardial infarction, congestive heart failure, or CVD death) through February 2011 were identified and adjudicated. The prevalence of low, medium, and high adherence was 4.5, 23.7, and 71.8% for MPR and 14.0, 34.3, and 51.8% for MMAS-8, respectively. During a median of 3.8 years' follow-up, 240 (11.5%) people had a CVD event. Low MPR and low MMAS-8 were associated with uncontrolled BP at baseline and during follow up. After multivariable adjustment and compared to those with high MPR, the hazard ratios for CVD associated with medium and low MPR were 1.17 [95% confidence interval (CI) 0.87-1.56)] and 1.87 (95% CI: 1.06-3.30), respectively. Compared to those with high MMAS-8, the hazard ratios (95% CI) for MMAS-8 for medium and low MMAS-8 were 1.04 (0.79-1.38) and 0.89 (0.58-1.35), respectively. CONCLUSION: While both adherence measures were associated with BP control, pharmacy refill but not self-report antihypertensive medication adherence was associated with incident CVD. The differences in these associations may be because of the distinctions in what each adherence measure assesses.

RESUMO

BACKGROUND: Medicaid patients tend to have poor access to care and suffer from more obesity and obesity-related co-morbidities compared to their privately insured counterparts. The impact of Medicaid status on outcomes after laparoscopic sleeve gastrectomy (LSG) is unknown. The aim of this study was to identify factors that influence outcomes following LSG in the adult Medicaid population of Louisiana with particular focus on adherence to bariatric aftercare attendance and access to care. METHODS: A retrospective review of 63 Medicaid patients undergoing LSG was performed. Demographic data, access to care, weight, co-morbidities morbidity, and mortality were analyzed. Changes in weight and obesity-related co-morbidities were analyzed for patients with ≥12 months of follow-up. Regression analyses were used for estimating the relationships among variables. RESULTS: The majority of patients were female and non-Caucasian. The mean age was 38.6 years. Morbidity was 16% and mortality was 0%. The average distance traveled to clinic was 71.9 miles. Within the first year only 10% of the patients attended all post-operative clinic visits. A multiple logistic model showed that the only predictor of clinic attendance was increased age. At a mean follow-up of 17.7 months, the mean percent excess body weight loss was 47.2%. Greater pre-surgical weight was the only variable associated with suboptimal weight loss. Improvement or resolution of all major co-morbidities was seen in 65% of patients. CONCLUSION: Medicaid patients had a poor attendance at bariatric surgery follow up appointments. Since long-term follow-up is critical, we needed to develop strategies that will optimize follow-up in this patient population.

RESUMO

BACKGROUND: Cardiovascular risk factors in childhood are predictive of adulthood arterial stiffness. However, it is unknown whether this relationship varies by race or sex. METHODS: Six hundred and eighty adults aged 24 to 43 had been followed for an average of 26.3 years, from the Bogalusa Heart Study. Brachial to ankle pulse wave velocity (baPWV) measured by an automatic oscillometric technique was used as the outcome variable for arterial stiffness during adulthood. Body mass index (BMI), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), glucose, and systolic blood pressure (SBP), all measured in childhood, were used as predictors. The average values of childhood measurements at multiple time points were used, standardized to age, race, and sex-specific z-scores. RESULTS: In the total sample, childhood SBP was the only significant predictor (P < 0.001) for adult baPWV. Significant interactions between sex and BMI (P = 0.001), between sex and LDL-C (P = 0.035), and between race and HDL-C (P = 0.002) on adult baPWV were identified. Childhood predictors of adult baPWV were BMI (30.9 cm/s reduction in baPWV per standard deviation increase, 95% confidence interval [CI]: -55.0, -6.9 cm/s), LDL-C (30.8 cm/s increase, 95% CI: 2.9, 59.5 cm/s), and HDL-C (46.8 cm/s reduction, 95% CI: -76.2, -17.4 cm/s) in white males; SBP (38.2 cm/s increase, 95% CI: 11.0, 65.4 cm/s) in white females; BMI (71.3 cm/s reduction, 95% CI: -119.9, -22.7 cm/s) in black males; and none in black females. CONCLUSIONS: The associations of childhood cardiovascular risk factors with adult arterial stiffness varied by race and sex.

RESUMO

Ventral hernias are a common clinical problem. Immediate repair is recommended for most ventral hernias despite significant recurrence rates. This practice may be related to a lack of understanding of the natural history of ventral hernias. The purpose of this study was to determine the natural history of ventral hernias and to determine if watchful waiting is an acceptable and safe option. Forty-one patients with ventral hernias were enrolled in a longitudinal cohort study of watchful waiting. Primary outcomes were functional impairment resulting from hernia disease as measured by the Activities Assessment Scale (AAS) and changes from baseline to two years in the physical and mental component score of the SF-36 Health Survey. Secondary outcomes included complications such as incarceration. Mixed-effects model for repeated measures and Student's t tests were used to evaluate scale performance. The mean age of enrollees was 64 years, and the mean hernia size was 239 cm(2). Eleven patients were lost to follow-up, and seven patients died of other causes. All remaining patients were followed for two years. There was one incarceration during the follow-up period. There was no deterioration in the AAS score (baseline vs 24 months = 28 vs 25, P = 0.60). There was deterioration of the physical functioning dimension of the SF-36 (baseline vs 24 months = 40 vs 32, P < 0.01), but the mental functioning dimension was improved (45 vs 51; P = 0.01). Watchful waiting was a safe option for patients in this study with ventral hernias.

RESUMO

This article explores cross-sectional associations between depressive symptoms and body mass index (BMI) in women working in schools in the Greater New Orleans area. Self-efficacy for eating and exercise, eating styles, and exercise are examined as potential pathways. This is a secondary data analysis of 743 women who were participating in a workplace wellness randomized controlled trial to address environmental factors influencing eating and exercise behaviors using baseline data prior to the intervention. BMI was the primary outcome examined. Path analysis suggested that increased depressive symptoms were associated with increased BMI in women. Indirect effects of depressive symptoms on BMI were found for increased healthy eating self-efficacy, increased emotional eating, and decreased exercise self-efficacy. The association between greater healthy eating self efficacy and BMI was unexpected, and may indicate a suppressor effect of eating self-efficacy in the relationship between depressive symptoms and BMI in women. The findings suggest the importance of depressive symptoms to BMI in women. Targets for interventions to reduce BMI include targeting depressive symptoms and related sequelae including self-efficacy for exercise, and emotional eating. Further investigation of eating self-efficacy and BMI are recommended with particular attention to both efficacy for health eating and avoidance of unhealthy foods.

RESUMO

OBJECTIVES: To examine self-reported exposure to a physical activity (PA) promoting intervention and changes to school environmental PA factors. METHODS: Randomly selected 8(th) grade girls in year 2 (N = 3469) and year 3 (N = 3462) completed surveys on exposure to the health education, PE components, PA programming, and PA supporting messages. Girls' perceptions of their school-environment and an assessment of school environmental factors by principals in support of PA also were measured. Analysis included generalized linear mixed models with random effects for site and school comparing intervention and control schools. RESULTS: Year 2 intervention girls reported greater exposure to all 4 components of the intervention compared to control school girls. In year 3, differences by treatment disappeared in all but 2 components. CONCLUSIONS: Intervention girls were exposed to TAAG in year 2 with effects diminishing in year 3.

RESUMO

As a biologically-mediated pathway between adversity and declines in physical health, allostatic load has been frequently hypothesized as a potential contributor to racial disparities in birth outcomes, but an empirical evidence is lacking. The purpose of this study was to examine the relationships between maternal preconception allostatic load, race, and adverse birth outcomes within the context of neighborhood-level poverty using data from the Bogalusa Heart Study. Allostatic load was quantified as a count of regulatory biomarkers falling in the highest risk quartile of the sample distribution as measured from a physical examination that took place prior to conception. Consistent with previous findings, African American women resided in more impoverished neighborhoods and had higher allostatic load scores compared to whites; however, allostatic load was not associated with preterm birth or low birth weight in fully adjusted models. These results underscore a need for further refinement of both biologic and contextual measures that capture holistically the way in which stressful conditions and experiences encountered across the life-course influence health potentials and engender inequities in reproductive health outcomes.

RESUMO

BACKGROUND: Large disparities in adverse birth outcomes persist between African American and white women in the US despite decades of research, policy, and public health intervention. Allostatic load is an index of dysregulation across multiple physiologic systems that results from chronic exposure to stress in the physical and socio-cultural environment which may lead to earlier health deterioration among racially or socio-economically disadvantaged groups. The purpose of this investigation was to examine relationships between maternal biomarkers of allostatic load prior to conception and the occurrence of preterm birth and small for gestational age infants among a cohort of white and African American women participants in the Bogalusa Heart Study. METHODS: Data from women participants were linked to the birth record of their first-born infant. Principal components analysis was used to construct an index of allostatic load as a summary of the weighted contribution of nine biomarkers representing three physiologic domains: cardiovascular, metabolic, and immune systems. A series of Poisson regression models based on samples ranging from 1467 to 375 women were used to examine race, individual biomarkers of allostatic load, and quartiles of the allostatic load index as predictors of preterm birth (n = 150, 10.2%) and small for gestational age (n = 135, 9.2%). RESULTS: There was no evidence of a relationship between maternal preconception allostatic load and either adverse birth outcome in this sample. Further, there was no evidence of effect modification of by race or education. CONCLUSIONS: More work is needed in understanding the biological mechanisms linking social inequities to racial disparities in adverse birth outcomes.

RESUMO

OBJECTIVE: To develop and evaluate a short self-report tool to predict low pharmacy refill adherence in older patients with uncontrolled hypertension. DESIGN: Cross-sectional analysis of survey and administrative data from the Cohort Study of Medication Adherence Among Older Adults (CoSMO). PARTICIPANTS: A total of 394 adults with uncontrolled blood pressure; mean ± SD age was 76.6 ± 5.6 years, 33.0% were black, 66.0% were women, and 23.4% had a low medication possession ratio (MPR). MEASUREMENTS AND MAIN RESULTS: We considered 164 self-reported candidate items for development of a prediction rule for low (less than 0.8) versus high (0.8 or more) MPR from pharmacy refill data. Risk prediction models were evaluated by using best subsets analyses, and the final model was chosen based on clinical relevance and model parsimony. Bootstrap simulations assessed internal validity. The performance of the final four-item model was compared to the eight-item Morisky Medication Adherence Scale (MMAS-8) and the nine-item Hill-Bone Compliance Scale. The four-item self-report tool for predicting pharmacy refill adherence showed moderate discrimination (C statistic 0.704, 95% confidence interval [CI], 0.683-0.714) and good model fit (Hosmer-Lemeshow χ² = 1.238, p=0.743). Sensitivity and specificity were 67.4% and 67.8%, respectively. The concordance (C) statistics for MMAS-8 and the Hill-Bone Compliance Scale were lower at 0.665 (95% CI 0.632-0.683) and 0.660 (95% CI 0.622-0.674), respectively. CONCLUSION: A four-item self-report tool moderately discriminated low from high pharmacy refill adherers, and its test performance was comparable with existing eight- and nine-item adherence scales. Parsimonious self-report tools predicting low pharmacy refill in patients with uncontrolled blood pressure could facilitate hypertension management in the elderly.

RESUMO

OBJECTIVES: To determine whether sociodemographic, clinical, healthcare system, psychosocial, and behavioral factors are differentially associated with low antihypertensive medication adherence scores in older men and women. DESIGN: Cross-sectional analysis of baseline data. SETTING: Cohort Study of Medication Adherence in Older Adults (N = 2,194). MEASUREMENTS: Low antihypertensive medication adherence was defined as a score less than 6 on the 8-item Morisky Medication Adherence Scale. Information on risk factors for low adherence was collected using telephone surveys and administrative databases. RESULTS: The prevalence of low medication adherence scores did not differ according to sex (women, 15.0%; men 13.1%; P = .21). In sex-specific multivariable models, having problems with medication cost and practicing fewer lifestyle modifications for blood pressure control were associated with low adherence scores in men and women. Factors associated with low adherence scores in men but not women were poor sexual functioning (odds ratio (OR) = 2.03, 95% confidence interval (CI) = 1.31-3.16 for men and OR = 1.28, 95% CI = 0.90-1.82 for women), and body mass index of 25.0 kg/m(2) or more (OR = 3.23, 95% CI = 1.59-6.59 for men; OR = 1.23, 95% CI = 0.82-1.85 for women). Factors associated with low adherence scores in women but not men included dissatisfaction with communication with their healthcare provider (OR = 1.75, 95% CI = 1.16-2.65 for women; OR = 1.16, 95% CI = 0.57-2.34 for men) and depressive symptoms (OR = 2.29, 95% CI = 1.55-3.38 for women; OR = 0.93, 95% CI = 0.48-1.80 for men). CONCLUSION: Factors associated with low antihypertensive medication adherence scores differed according to sex. Interventions designed to improve adherence in older adults should be customized to account for the sex of the target population.

RESUMO

PURPOSE: To examine "travel by walking" (TBW) before and after school among eighth-grade girls. METHODS: Participants attended 36 middle schools from Arizona, Maryland, Minnesota, Louisiana, California, and South Carolina participating in the Trial of Activity for Adolescent Girls. The cross-sectional sample consisted of 3,076 eighth-grade girls, and the longitudinal sample included 1,017 girls who participated in both sixth and eighth grades. Before- or after-school TBW status was determined from the 3-Day Physical Activity Recall. The main outcomes were body mass index and physical activity, which was measured by accelerometry, estimated for total physical activity (light, moderate, vigorous) and moderate-to-vigorous physical activity (MVPA). RESULTS: Eighth-grade girls who reported TBW had 4 more minutes (95% confidence interval = 2.1-6.1) of MVPA before and after school than nonwalkers, and 2 more minutes of MVPA (95% confidence interval = 1.1-3.1) on an average weekday. In the longitudinal sample, girls who reported TBW before and after school in both sixth and eighth grades (consistent walkers) accumulated more minutes of MVPA for an average weekday than inconsistent walkers in both sixth (27 ± 2.2 vs. 25 ± 1.9 minutes; p = .03) and eighth (28 ± 2.6 vs. 25 ± 2.3 minutes; p = .003) grades. There were no differences in body mass index by walking status. CONCLUSIONS: Adolescent girls who reported TBW before and after school accumulated more minutes of MVPA than nonwalkers. Efforts to prevent the decline in walking to school in middle school girls could contribute to their overall physical activity.

RESUMO

The authors examined the association between life events and antihypertensive medication adherence in older adults and the moderating role of coping. A cross-sectional analysis was conducted by using data (n = 1,817) from the Cohort Study of Medication Adherence among Older Adults (recruitment conducted from August 2006 through September 2007). Life events occurring in the 12 months preceding the study interview were assessed via the Holmes Rahe Social Readjustment Rating Scale (SRRS), and coping levels were assessed via an adapted version of the John Henry Active Coping Scale. Low adherence to antihypertensive medication was defined as scores less than 6 on the 8-item Morisky Medication Adherence Scale (known as "MMAS-8"). Of study participants, 13.2% had low adherence, and 27.2% and 5.0% had medium (150-299) and high (≥300) SRRS scores, respectively. After multivariable adjustment, the odds ratios for low adherence associated with medium and high, versus low, SRRS were 1.50 (95% confidence interval: 1.11, 2.02) and 2.11 (95% confidence interval: 1.24, 3.58), respectively. When multivariable models were stratified by coping level, the association between life events and adherence was evident only among participants with low coping levels.

RESUMO

OBJECTIVE: We assessed serum homocysteine (tHcy) and folate concentrations among US adolescents before and after fortification of cereal-grain products with folic acid, and associations with demographic, behavioural and physiological factors. DESIGN: Observational study conducted among participants of a randomized trial. SETTING: The Child and Adolescent Trial for Cardiovascular Health (CATCH) study. SUBJECTS: Adolescents (n 2445) in grades 8 (pre-fortification, mean age 14 years) and 12 (post-fortification, mean age 18 years). RESULTS: Average serum concentrations of tHcy, folate and vitamin B6 increased by 17 %, 16 % and 14 %, respectively, while serum concentrations of vitamin B12 decreased by 11 % post-fortification. Folic acid fortification provided, on average, an additional intake of 118 µg folate/d. Male sex (P < 0.0001) and white race (P = 0.0008) were associated with significantly greater increases in tHcy concentration, while increases in BMI (P = 0.006) and serum folate concentration (P < 0.0001) were associated with significant decreases in tHcy concentration. Female sex (P < 0.0001), non-smoking (P < 0.0001), use of multivitamins (P < 0.0001) and higher dietary intake of folate (P = 0.001) were associated with significantly greater increases in serum folate concentrations. From grade 8 to grade 12, the upward age trend in serum tHcy concentration was uninterrupted in its course (P > 0.50); whereas serum folic acid concentration showed a downward trend that incurred a discrete jump upward (17 % higher; P < 0.0001) with fortification. These trends differed significantly for males v. females (P < 0.001 for interaction). CONCLUSIONS: Fortification had a significant impact on improving folate status but not serum tHcy concentrations among US adolescents.
