Abstract Background and Purpose. Little is known about predictors of dropout status in exercise studies for people with osteoarthritis. Losses to follow-up can pose serious threats to study validity. The purpose of this study was to assess the ability of arthritis medication usage the month prior to enrollment to predict dropout status among participants in an exercise study for people with osteoarthritis. Subjects and Methods. Men and women who participated in an exercise study for people with osteoarthritis (N=143) were followed. Participants who completed 24+ months of the exercise program were considered retained, whereas individuals who withdrew prior to 24 months were considered dropouts. Results. Of the 143 participants analyzed, 78 (55%) completed 24+ months of the exercise program and 65 (45%) dropped out. Among those who reported arthritis medication usage, 54% were lost to follow-up. The group reporting no usage of arthritis medication had a 20% dropout rate (odds ratio=3.5, 95% confidence interval=1.6–7.6). The final adjusted model controlling for baseline health status, body mass index, and the interaction between baseline health status and body mass index indicated that those individuals who reported arthritis medication usage were more than 4 times more likely to drop out than were those who reported no arthritis medication usage (odds ratio=4.5, 95% confidence interval=1.8–11.4). Discussion and Conclusion. The results showed that self-reported arthritis medication usage the month prior to study enrollment was associated with subsequent dropout status among this group of exercisers with osteoarthritis. Further identification of baseline characteristics predictive of participant dropout status may benefit future exercise studies. A priori knowledge of “at-risk” exercise study participants will afford the opportunity for the timely allocation of appropriate resources aimed at reducing losses to follow-up.

Background Atrial fibrillation is the most common heart rhythm disorder, and high body mass index is a well-established risk factor for atrial fibrillation. The objective of this study was to examine the associations of physical activity and body mass index and risk of atrial fibrillation, and the modifying role of physical activity on the association between body mass index and atrial fibrillation. Design The design was a prospective cohort study. Methods This study followed 43,602 men and women from the HUNT3 study in 2006–2008 until first atrial fibrillation diagnosis or end of follow-up in 2015. Atrial fibrillation diagnoses were collected from hospital registers and validated by medical doctors. Cox proportional hazard regression analysis was performed to assess the association between physical activity, body mass index and atrial fibrillation. Results During a mean follow-up of 8.1 years (352,770 person-years), 1459 cases of atrial fibrillation were detected (4.1 events per 1000 person-years). Increasing levels of physical activity were associated with gradually lower risk of atrial fibrillation ( p trend 0.069). Overweight and obesity were associated with an 18% (hazard ratio 1.18, 95% confidence interval 1.03–1.35) and 59% (hazard ratio 1.59, 95% confidence interval 1.37–1.84) increased risk of atrial fibrillation, respectively. High levels of physical activity attenuated some of the higher atrial fibrillation risk in obese individuals (hazard ratio 1.53, 95% confidence interval 1.03–2.28 in active and 1.96, 95% confidence interval 1.44–2.67 in inactive) compared to normal weight active individuals. Conclusion Overweight and obesity were associated with increased risk of atrial fibrillation. Physical activity offsets some, but not all, atrial fibrillation risk associated with obesity.

Background: Clinical trials have demonstrated health status benefit of transcatheter mitral valve repair (TMVr) with MitraClip in patients with mitral valve regurgitation. Real-world site-level variability in health status outcomes for TMVr, and factors associated with this variability, are unknown. Methods: All patients undergoing TMVr procedure with MitraClip between November 2013 and March 2019 in the Transcatheter Valve Therapy Registry were included. Health status was measured at baseline and 30 days with the Kansas City Cardiomyopathy Questionnaire (KCCQ) Overall Summary (OS) score. Site-level variability in 30-day change in KCCQ-OS was examined by calculating the median odds ratio from a hierarchical logistic regression model, with ≥20-point improvement as the dependent variable. To define the extent to which patient characteristics, procedural characteristics (residual mitral valve regurgitation, periprocedural bleeding), site volume, and patients’ baseline health status accounted for variability in outcomes, the proportion of variability ( R 2 ) explained by sequentially adding these variables to the model was quantified. Results: Across 339 sites, 12 415 patients (mean age 79.0±9.5 years, 46.1%. females, 89.5% White) completed baseline and 30-day health status assessments. Mean KCCQ-OS score was 43.0±24.4 at baseline and 67.0±24.9 at 30-day follow-up. Across sites, the proportion of patients achieving a ≥20-point improvement in KCCQ-OS ranged from 12.5% to 100% and the adjusted median odds ratio was 1.58 (95% CI, 1.46–1.69). The greatest contribution to the variability in health status outcomes was from patients’ baseline KCCQ-OS score ( R 2 =25%) with <1% of the variability explained by patient and procedural characteristics, and annual site volume. Conclusions: There is moderate variation across sites in their patients’ achievement of health status benefits from TMVr, with patient’s baseline health status accounting for the largest proportion of this variation. This underscores the importance of patient selection in supporting more consistent health status benefit from TMVr.

Background and ObjectivesHigh plasma concentration of fibroblast growth factor 23 (FGF23) is a risk factor for left ventricular hypertrophy (LVH) in adults with CKD, and induces myocardial hypertrophy in experimental CKD. We hypothesized that high FGF23 levels associate with a higher prevalence of LVH in children with CKD.Design, setting, participants, & measurementsWe performed echocardiograms and measured plasma C-terminal FGF23 concentrations in 587 children with mild-to-moderate CKD enrolled in the Chronic Kidney Disease in Children (CKiD) study. We used linear and logistic regression to analyze the association of plasma FGF23 with left ventricular mass index (LVMI) and LVH (LVMI ≥95th percentile), adjusted for demographics, body mass index, eGFR, and CKD-specific factors. We also examined the relationship between FGF23 and LVH by eGFR level.ResultsMedian age was 12 years (interquartile range, 8–15) and eGFR was 50 ml/min per 1.73 m2 (interquartile range, 38–64). Overall prevalence of LVH was 11%. After adjustment for demographics and body mass index, the odds of having LVH was higher by 2.53 (95% confidence interval, 1.28 to 4.97; P<0.01) in participants with FGF23 concentrations ≥170 RU/ml compared with those with FGF23<100 RU/ml, but this association was attenuated after full adjustment. Among participants with eGFR≥45 ml/min per 1.73 m2, the prevalence of LVH was 5.4%, 11.2%, and 15.3% for those with FGF23 <100 RU/ml, 100–169 RU/ml, and ≥170 RU/ml, respectively (Ptrend=0.01). When eGFR was ≥45 ml/min per 1.73 m2, higher FGF23 concentrations were independently associated with LVH (fully adjusted odds ratio, 3.08 in the highest versus lowest FGF23 category; 95% confidence interval, 1.02 to 9.24; P<0.05; fully adjusted odds ratio, 2.02 per doubling of FGF23; 95% confidence interval, 1.29 to 3.17; P<0.01). By contrast, in participants with eGFR<45 ml/min per 1.73 m2, FGF23 did not associate with LVH.ConclusionsPlasma FGF23 concentration ≥170 RU/ml is an independent predictor of LVH in children with eGFR≥45 ml/min per 1.73 m2.

Abstract Objectives The aim of the study was to assess the association between blood pressure (BP) values and sodium intake from snacks. Methods The mean weekly consumption of snacks was evaluated in 1500 randomly selected undergraduate aged 16–24 years by a food frequency questionnaire. Participants were divided into quartiles of systolic blood pressure and diastolic blood pressure. The mean weekly exercise level was calculated as the product of duration and frequency of each activity (in hours/week), weighted by an estimate of the metabolic equivalent of the activity (MET) and summed for the activities performed. The whole cohort was divided into tertiles of exercise and the individuals were classified as; sedentary, moderately active and active. The cut of points in the whole cohort were respectively; ≤10, 11–29, ≥30 MET h/week. Exercise levels were therefore expressed as MET h/week. Results The mean age, metabolic equivalent of activity (METs), body mass index (BMI) and mean sodium intake from snacks per day were; 20.10 ± 1.44 years, 25.51 ± 10.03 METs h/week, 24.86 ± 4.80 kg/m2 and 1.5 g/day respectively. Systolic blood pressure (SBP) ranges between 104.43 ± 4.89 mmHg and 137.27 ± 16.71 mmHg while the diastolic blood pressure (DBP) ranges from 71.24 ± 7.83–83.11 ± 12.03 mmHg. The SBP and DBP significantly increased from the lower to the higher tertile of sodium from snacks and with increasing frequency of salty snacks consumption (P &lt; 0.001). In the multiple logistic regression model, being in the highest SBP quartile (≥115 mmHg) was significantly associated with consumption of sodium from snacks (odds ratio (OR) = 1.46; 95% confidence interval (CI) 1.13–1.82; P = 0.001), age, gender and body mass index. Also, being in the highest DBP quartile (≥70 mmHg) was significantly associated with consumption of sodium from snacks (odds ratio (OR) = 2.84; 95% confidence interval (CI) 1.41–5.69; P = 0.003), age, body mass index, but not with gender. Conclusions The study has shown that a strong association exists between sodium intake from snack, daily frequency of consumption of salty snacks and blood pressure. Public education and social marketing are needed to motivate the undergraduate to choose healthier snacks with lower sodium content. Funding Sources The study did not receive any funding from any source.

Background: Many epidemiologic studies have been conducted to assess factors that were associated to endometriosis, but there is no consistency in results. Therefore, we conducted this meta-analysis to investigate the association between body mass index and the risk of endometriosis. Methods: In this meta-analysis, relevant studies that published in major international electronic bibliographic databases of PubMed, Scopus and Web of Science were systematically searched during November 2017. The Begg and Egger’s test was used to investigate publication bias in included studies. The Q-statistic and I2 tests were carried out for measuring heterogeneity. The random-effects model was conducted to obtain pooled odds ratio. Results: Our results showed a direct association between underweight and endometriosis in woman (odds ratio = 1.41, 95% confidence interval = 1.16–1.66), so underweight woman had 41% higher chance for endometriosis. However, we did not find linear association between overweight and endometriosis (odds ratio = 0.95; 95% confidence interval: 0.72–1.18) and obesity and endometriosis (odds ratio = 0.88; 95% confidence interval: 0.54–1.21), respectively. Conclusions: Our results suggested that underweight was a risk factor for the endometriosis, while overweight and obesity were not protective factors for endometriosis.

This study examined isolated and combined associations of physical activity (PA) and sitting time (ST) with body mass index (BMI) among older Brazilian adults. We have analyzed baseline data of 8,177 participants aged 50 years and older from the Brazilian Longitudinal Study of Aging. Respondents were categorized into sufficient PA/low ST, sufficient PA/high ST, insufficient PA/low ST, or insufficient PA/high ST using the Short Version of International Physical Activity Questionnaire. Multinomial logistic regression analysis examined the associations of being underweight (BMI, <18 kg/m2), overweight (BMI, 25–29.9 kg/m2), and obese (BMI, ≥30 kg/m2) with PA and ST categories. High ST (≥165 min/day) was associated with overweight (odds ratio, 1.26; 95% confidence interval [1.11, 1.44]) and obesity (odds ratio, 1.43; 95% confidence interval [1.21, 1.70]). However, no association was observed between PA and BMI. Participants in the insufficient and sufficient PA/high ST categories were more likely to be obese after adjusting for sociodemographic and health condition. Our findings call for public health initiatives that consider reducing ST in older adults.

This study presents a 2-yr follow-up of 281 patients, aged 15–34 yr, diagnosed with diabetes between 1992 and 1993. At diagnosis, 224 (80%) patients were positive for at least one of the following autoantibodies: islet cell antibodies (ICAs), glutamic acid decarboxylase antibodies (GADAs), or tyrosine phosphatase antibodies (IA-2As); the remaining 57 (20%) patients were negative for all three autoantibodies. At diagnosis, C-peptide levels were lower (0.27; 0.16–0.40 nmol/L) in autoantibody-positive patients compared with autoantibody-negative patients (0.51; 0.28–0.78 nmol/L; P &lt; 0.001). After 2 yr, C-peptide levels had decreased significantly in patients with autoimmune diabetes (0.20; 0.10–0.37 nmol/L; P = 0.0018), but not in autoantibody-negative patients. In patients with autoimmune diabetes, a low initial level of C-peptide (odds ratio, 2.6; 95% confidence interval, 1.7–4.0) and a high level of GADAs (odds ratio, 2.5; 95% confidence interval, 1.1–5.7) were risk factors for a C-peptide level below the reference level of 0.25 nmol/L 2 yr after diagnosis. Body mass index had a significant effect in the multivariate analysis only when initial C-peptide was not considered. Factors such as age, gender, levels of ICA or IA-2A or insulin autoantibodies (analyzed in a subset of 180 patients) had no effect on the decrease in β-cell function. It is concluded that the absence of pancreatic islet autoantibodies at diagnosis were highly predictive for a maintained β-cell function during the 2 yr after diagnosis, whereas high levels of GADA indicated a course of decreased β-cell function with low levels of C-peptide. In autoimmune diabetes, an initial low level of C-peptide was a strong risk factor for a decrease in β-cell function and conversely high C-peptide levels were protective. Other factors such as age, gender, body mass index, levels of ICA, IA-2A or IAA had no prognostic importance.

Background Socio-economic position and intelligence predict coronary heart disease but their mutual associations are not yet well understood. We investigated associations between intelligence and coronary heart disease mortality and explored if they are confounded or modified by socio-economic position. Design This was a cohort-based follow-up study. Methods Data on intelligence, systolic and diastolic blood pressures and body mass index were measured at conscription examination at age 18 years in 682 361 Swedish men born 1951-1965. Data on parental and own education and social position were derived from censuses in 1960, 1970, 1980 and 1990. Follow-up data up to end of 2001 were derived from the Swedish Cause of Death Register and 737 coronary heart disease deaths were observed. Data were analyzed by Cox regression and conditional logistic regression models. Results An inverse association was found between intelligence and coronary heart disease mortality after adjustment for parental and own education and social position, body mass index and blood pressure (hazard ratio 0.92; 95% confidence interval 0.88-0.96). These associations were of similar strengths within all socio-economic categories and also found within 215 brother pairs discordant for coronary heart disease mortality and intelligence (odds ratio 0.76; 95% confidence interval 0.58-1.00). Conclusions Intelligence is associated with coronary heart disease mortality independently of socio-economic position. Health education messages should be tailored according to intellectual performance of the recipients, but also other factors are important for socio-economic coronary heart disease inequalities.

Background: Employee examination is one of the requirements of the occupational health care system. The present study aimed to evaluate the current health status of the staff working in an Iranian gas company to prevent, follow-up, and treat the disease. Methods: This cross-sectional descriptive-analytical study was conducted on the data collected from health screening of 94 service personnel in one of the gas companies in Iran. Data were collected by the 4-sheet forms of occupational examinations containing the following information: demographic data, general health status (blood pressure, smoking, allergy history, surgery, occupational accidents, body mass index), cardiovascular system, musculoskeletal, liver, kidney, gastrointestinal, clinical examination, paraclinical evaluations of the internal gland, cholesterol, triglycerides, liver enzymes, and hematopoietic system (CBC). Data were analyzed using SPSS 25. Results: All participants were male with an average (Standard Deviation) age and BMI of 42.96 ± 8.00 and26.83 ± 4.08, respectively. The participantschr('39') body mass index indicated that 45 staff (48.38%) were overweight and 15 individuals (16.12%) were in the range of obesity. The participants had history of smoking (22.3%), cholesterol above 200 (27.7%), and triglycerides above 300 (8/5%). The rate of hypermetropia, musculoskeletal disease, hypertension, high blood concentration and low blood platelets, hyperglycemia, cardiovascular disease, and kidney disease were 25.80%, 24.5%, 9.6%, 56.4%, 7.4%, 1.1%, and 12.8%, respectively. Conclusion: Although the studied company has a yearly occupational medical examination, the workers have not been provided with a comprehensive report and appropriate feedback. Therefore, it is essential to follow up the health reports and examinations and refer the patients to the related physicians.
