Abstract Background In women of Minangkabau ethnicity, a high prevalence of dyslipidemia, overweight, and obesity is thought to be closely related to poor dietary practices. Promotion of local specific food-based recommendations (FBRs) was previously found to be effective in improving dietary practice and nutrient intakes related to dyslipidemia. This study aimed to describe the effects of the FBR promotion on the nutritional status and lipid profiles of Minangkabau women with dyslipidemia. Methods We used a cluster-randomized design with a total subject of 123 Minangkabau women of reproductive age with dyslipidemia. They were recruited from 16 sub-villages and assigned to either the FBR group (n = 61) or the non-FBR group (n = 62). Data on body weight, height, waist circumference, and lipid profiles were collected at the baseline and the end of the trial. Linear mixed model analysis was used to analyze the effect of the intervention on nutritional status and lipid profiles. Results The mean effect (95% confidence interval) of the intervention on body weight, body mass index, and waist circumference for the FBR group versus the non-FBR group were -1.1 (-1.8; -0.39) kg, -0.43(-0.76; -0.11) kg/m2 and -2.1(-3.7;-0.46) mm respectively (p <0.05). The Castelli’s index in the FBR group improved, but there was no significant between-group difference in the change of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides at the end of the intervention. Conclusion The promotion of the FBRs positively impact the nutritional status but did not significantly affect the blood lipid profile of Minangkabau women with dyslipidemia. Trial Registration The trial was retrospectively registered at ClinicalTrials.gov Protocol Registration and Result System (PRS) as NCT04085874, in September 2019.

The Impact

Objective.To determine the accuracy of self-reported body weight prior to and following a weight loss intervention including daily self-weighing among obese employees.Methods.As part of a 6-month randomized controlled trial including a no-treatment control group, an intervention group received a series of coaching calls, daily self-weighing, and interactive telemonitoring. The primary outcome variable was the absolute discrepancy between self-reported and measured body weight at baseline and at 6 months. We used general linear mixed model regression to estimate changes and differences between study groups over time.Results.At baseline, study participants underreported their weight by an average of 2.06 (se=0.33) lbs. The intervention group self-reported a smaller absolute body weight discrepancy at followup than the control group.Conclusions.The discrepancy between self-reported and measured body weight appears to be relatively small, may be improved through daily self-monitoring using immediate-feedback telehealth technology, and negligibly impacts change in body weight.

The objective of this study was to provide a morphometric description of the caudal cervical intervertebral disc (IVD) spaces of small-breed dogs and cats. Specimens consisting of C4 through C7 from five small-breed dogs and six cats were positioned in neutral, flexion, extension, and lateral bending positions; and CT images were acquired. Height and width of the cranial and caudal vertebral endplates (VEPs), angle between the VEPs (IVD wedge angle), and craniocaudal distance (IVD width) between VEPs for the four loading positions were measured and compared for three segments (C4–C5, C5–C6, and C6–C7). VEP size normalized to body weight from medium-sized dogs was retrieved from a previous study and compared with data from small dogs and cats. A linear mixed model was used to compare outcome measures. Significance was set to p &lt; 0.05. VEP size normalized to body weight was the largest in small dogs compared with cats (p = 0.0422) and medium-sized dogs (p = 0.0064). Cats and medium-sized dogs were similar (p = 0.2763) in this regard. Flexion and extension induced a reduction of IVD width in the ventral portion of the IVD and the area of the nucleus. The dorsal part of the IVD remained unchanged throughout loading conditions. Unique morphometric characteristics of the caudal cervical IVD space of small dogs and cats were detected that are different from those described in sizes of dogs (medium-sized) typically affected by caudal cervical spondylomyelopathy (CSM). These findings may help to understand the different pathomechanisms in cervical spinal disease between small- and medium-sized dogs, including caudal CSM.

Abstract Cardiovascular disease (CVD) is a major cause of death among people living in the United States. Populations, especially minorities, living in the rural South are disproportionately affected by CVD and have greater CVD risk, morbidity and mortality. Culturally relevant cardiovascular health programs implemented in rural community settings can potentially reduce CVD risk and facilitate health behavior modification. The purpose of this study was to examine the effects of a cardiovascular health promotion intervention on the health habits of a group of rural African American adults. The study had a cluster randomized controlled trial design involving 12 rural churches that served as statistical clusters. From the churches (n = 6) randomized to the intervention group, 115 participants were enrolled, received the 6-week health program and completed pretest–posttest measures. The 114 participants from the control group churches (n = 6) did not receive the health program and completed the same pretest–posttest measures. The linear mixed model was used to compare group differences from pretest to posttest. The educational health intervention positively influenced select dietary and confidence factors that may contribute toward CVD risk reduction.

Abstract Objectives The objective of this study was to determine whether a novel fiber formulation improves glucose, insulin, and lipid profiles in overweight men and women consuming a low fiber diet. Methods Twenty individuals were enrolled in this randomized order, placebo-controlled, cross-over study. Participants were young, healthy, overweight (BMI 23.0–32.0) and consumed &lt;15 g/day of fiber. All participants consumed the fiber and placebo supplement for a period of 4 weeks each, with a 4-week washout between intervention arms. Participants recorded their diet for 3 days using dietary records twice during each 4-week segment. They consumed either fiber and/or placebo packet containing a total of 12 g/serving per day. The Fiber and/or Placebo was given out as powder form which include mostly dietary fiber (resistant starch, fructooligosaccharide, sugarcane fiber, and inulin), rice flour, xanthan gum, and fruit powders that was mixed with water for consumption. Questionnaires, anthropometric measurements, blood draws, and stool samples were collected at each study visit. Changes in glucose, insulin, and lipid profile (total cholesterol (TC), triacylglycerols (TG), HDL-C and calculated LDL-C) were assessed using a linear mixed model. Results The mean change in fasted glucose, insulin, and lipid profiles showed a tendency to decrease in response to fiber consumption compared with the placebo but did not meet statistical significance (P = 0.29, 0.42, and 0.61) due to high interindividual variability. This clinical trial was registered at clinicaltrials.gov as NCT03785860. Conclusions Cardiometabolic profiles did not change in response to the fiber supplement.

The Relationship

The patients with obesity are known to suffer 25-hydroxy vitamin D (25(OH)D) deficiency, but the relationship between these two conditions remains unclear. The blood 25(ON)D levels in practically healthy women were compared with the amount and distribution patterns of the fatty tissue and with the content of plasma adipocytokines. The absence or deficit of vitamin D was documented in 61.3% of the women included in the present study. They exhibited negative correlation between 25(ON) D levels and body weight. The patients with obesity were characterized by correlation between the 25(ON)D levels and waist circumference, body weight, BMI, and the amount of fatty tissue. The women of reproductive age with the reduced blood 25(ON)D level (OR 1.86 [0.88—3.95]; CI 95%) or 25(ON)D deficiency (OR 2.23 [1.03—4.80]; CI 95%) were at a higher risk of development of obesity compared with the women in whom the 25(ON)D levels were in excess of 75 nmol/l. The study confirmed correlations between adypocytokine levels and the amount of fatty tissue even though it failed to demonstrate a significant relationship between the levels of adipocytokines and vitamin D.

The Relationship

Introduction: Overweight and obesity are pathologies that are increasing every day. This study was aimed to determine the relationship between anthropometric variables and lipid profiles in a sample of young university students, which leads to taking future prevention actions. Materials and Methods: A descriptive correlational study was conducted with a sample of 182 university students (88 women and 94 men), whose anthropometric variables and lipid profiles were evaluated. Data were analyzed using the SPSS Statistics 20 software. The sample distribution was analyzed using the Kolmogorov-Smirnov normality test. Results were expressed as mean ± standard deviation or percentage, as applicable. Significance was established under the Pearson’s correlation coefficient with p ≤0.05 value. Partial correlations were used to evaluate the relationship between each of the anthropometric risk indices and lipid profile values. Results: 46.7% of the population were overweight classifies as low-risk for waist circumference (45.1%), finding that the body adiposity index was healthy for their age in 64.5% of the participants. As for lipid profile, normal values for triglycerides were found in 60.4% of the participants and optimal values for total cholesterol in 56%. Correlational analysis with a significance of p≤0.005 was positive for gender with anthropometric variables such as Body Mass Index and waist circumference. Discussion: Anthropometric characteristics are closely related to the lipid profile behavior, as shown in this study, and the different research studies conducted with university students. Conclusions: Anthropometric variables are positively related to the gender of university students, finding an association between total cholesterol and triglycerides, which indicates a health risk factor.

Combat sports have a great interest in society and among professional sports. They are an important group of sports in the Olympic Games, but the strategies carried out by athletes to reduce body weight for weighing day, is famously known, suffering the adverse physical and psychological effects of rapid weight loss. This could compromise not only the performance, but the health and development of young athletes. A total of 22 elite male judokas (18.05 ± 1.05 years old) were evaluated during four different competitions in one season; the variables of body weight, water levels, and lean and fat mass were measured by bioimpedance (BIA), (Tanita BC545N) during one season. Using the linear mixed model test, we found significant differences in bodyweight variable during the competitions 3–4. The water level variable showed significant differences in all competitions, except for 2–4. Body mass index was significantly different in all competitions, being higher in the later competitions, except between competitions 1–2 and 2–3. Judokas participate in weight loss methods for their weigh-in days. Furthermore, the age at which the athletes reduced their water levels are worrisome. These results could be used to create healthy programs, especially in elite judokas, in order to carry out strategies before, during, and after competitions with weight loss and controlled water levels increasing future performance and health.

Introduction: Workplace wellness programs offer opportunities for decreasing obesity in adults. The effectiveness of such programs varies and is influenced by key intervention components (e.g. duration, intensity, content). We developed a multicomponent workplace wellness program, MyWay to Health (MW2H), which was adapted from an evidence-based weight loss intervention with demonstrated efficacy and meets the 2013 Guideline for the Management of Overweight and Obesity in adults. The purpose of this one-group pretest-posttest study was to evaluate program acceptability and effectiveness of MW2H on primary and secondary outcomes. Hypotheses: We hypothesized that MW2H would result in 1) clinically meaningful weight loss of ≥5%, and 2) improvements in cardiometabolic indices. Methods: During weeks 1-26, participants met privately with an interventionist for up to 24 weekly, 40-minute sessions, receiving training in eating and physical activity behavior change, self-regulation, and socioenvironmental strategies. During weeks 27-52, participants received maintenance support through phone calls, email, or in-person visits. Our primary outcome was percent weight loss. Secondary outcomes included improvement in BMI, waist circumference, HbA1c, cholesterol, and blood pressure. Outcomes were compared at baseline and 26 weeks; body weight only was measured at 52 weeks. Wilcoxin Signed Rank Tests were used to examine outcomes. Results: Participants (N=154) were mostly female (85%), White (75%), had a median age of 50 (Interquartile Range (IQR): 17) years, a median baseline BMI of 34.7 (IQR: 8.8), a median household income of $70,000 (IQR: $50,000), and 54% had a college degree or higher. Median number of in-person sessions attended was 19 (IQR: 4.0). Percent weight loss at 26 weeks (median [IQR]: 7.5% [6.8%]) was clinically meaningful, with 71% of participants achieving ≥5% weight loss. Statistically significant improvements in BMI, waist circumference, HbA1c, HDL cholesterol, and systolic and diastolic blood pressure (p<0.001 for all) were observed. At week 52, body weight data were available for 106 (69%) participants. Median percent weight loss from baseline was 7.0% (IQR: 9.3%). Of participants who achieved ≥5% weight loss at week 26, 94% maintained this level of weight loss at week 52. Conclusions: The MW2H workplace wellness program was acceptable to participants, evidenced by high program attendance, and resulted in clinically meaningful and statistically significant improvements in body weight and cardiometabolic indices. A majority of participants achieved ≥5% weight loss by 26 weeks, and nearly all participants for whom data was available maintained this level of weight loss at week 52. Additional research is needed to optimize intervention components, identify factors that contribute to weight maintenance, and examine MW2H effectiveness in a more diverse population.

Abstract This investigation was initiated to control Aedes aegypti and Zika virus transmission in Caguas City, Puerto Rico, during the 2016 epidemic using Integrated Vector Management (IVM), which included community awareness and education, source reduction, larviciding, and mass-trapping with autocidal gravid ovitraps (AGO). The epidemic peaked in August to October 2016 and waned after April 2017. There was a preintervention period in October/November 2016 and IVM lasted until August 2017. The area under treatment (23.1 km2) had 61,511 inhabitants and 25,363 buildings. The city was divided into eight even clusters and treated following a cluster randomized stepped-wedge design. We analyzed pools of female Ae. aegypti adults for RNA detection of dengue (DENV), chikungunya (CHIKV), and Zika (ZIKV) viruses using 360 surveillance AGO traps every week. Rainfall, temperature, and relative humidity were monitored in each cluster. Mosquito density significantly changed (generalized linear mixed model; F8, 14,588 = 296; P < 0.001) from 8.0 ± 0.1 females per trap per week before the intervention to 2.1 ± 0.04 after the percentage of buildings treated with traps was 60% and to 1.4 ± 0.04 when coverage was above 80%. Out of a total 12,081 mosquito pools, there were 1 DENV-, 7 CHIKV-, and 49 ZIKV-positive pools from October 2016 to March 2017. Afterward, we found only one positive pool of DENV in July 2017. This investigation demonstrated that it was possible to scale up effective Ae. aegypti control to a medium-size city through IVM that included mass trapping of gravid Ae. aegypti females.

Researchers designing multisite and cluster randomized trials of educational interventions will usually conduct a power analysis in the planning stage of the study. To conduct the power analysis, researchers often use estimates of intracluster correlation coefficients and effect sizes derived from an analysis of survey data. When there is heterogeneity in treatment effects across the clusters in the study, these parameters will need to be adjusted to produce an accurate power analysis for a hierarchical trial design. The relevant adjustment factors are derived and presented in the current article. The adjustment factors depend upon the covariance between treatment effects and cluster-specific average values of the outcome variable, illustrating the need for better information about this parameter. The results in the article also facilitate understanding of the relative power of multisite and cluster randomized studies conducted on the same population by showing how the parameters necessary to compute power in the two types of designs are related. This is accomplished by relating parameters defined by linear mixed model specifications to parameters defined in terms of potential outcomes.
