The intermittent fasting diet has a historical past, but recently, it has regained popularity as a weight loss strategy for the general public. Athletes have also picked up this specialized diet in search of a competitive edge. There are ample studies testing athletes of all levels, but most do not include females or report sex-specific results. This systematic review aimed to identify current research on the effects of intermittent fasting in the understudied population of female athletes. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a comprehensive search was conducted in three databases, including PubMed, Cochrane, and SPORTDiscus, and a total of six studies with experimental or observational designs testing the various effects of intermittent fasting on physical, physiological, and psychological parameters were included. This systematic review shows that studies found significant changes in calorie and fluid intake, body composition, nutrient utilization, well-being, and athletic performances with no changes in muscle strength, ratings of perceived exertion, blood lactate levels, and cognitive function. Multiple studies in this review found mixed results on changes in heart rate and athletic performance (vertical jump height), and no studies found negative effects on athletic performance except in the survey of athletes’ perceptions. Due to conflicting results of current research, more studies are needed to determine the effects of intermittent fasting combined with continuous exercise on athletic women.

Objective: Evaluate how a social marketing approach compares to traditional nutrition education curriculum for promoting behavioral changes related to eating and food. Design: Nonequivalent comparison group, entry-exit design. Participants from 12 Kentucky counties assigned either comparison or pilot group. Comparison group received traditional nutrition education curriculum and pilot group received the social marketing program, Cook Together, Eat Together (CTET) curriculum. EFNEP’s Behavior Checklist and 24-Hour Dietary Recall were administered at entry and exit of the 8-week programs. Participants: Females (18-72 years of age) from families eligible to receive SNAP benefits (n=64 comparison group participants, n=60 pilot group participants). Intervention: Comparison group completed an 8-week standard lesson and pilot group completed CTET program in varying time frames (1-8 weeks). Main Outcome Measures: Eating behavior changes between entry and exit for comparison versus pilot. Analysis: Quantitative data were analyzed using independent and paired t-tests with significance of P≤ 0.05 and 0.10. Results: Groups were demographically similar. Both had significant differences in entry and exit scores for Behavior Checklist and 24-Hour Recall (P≤ 0.05). Conclusion and Implications: Positive behavior change was observed in both comparison and pilot groups. A social marketing program proves to be a promising approach to nutrition education.

The purpose of this study was to describe diet and/or physical activity-based interventions and their control in cardiometabolic risk factors of diabetes for the South Asian (SA) population. A systematic review was conducted in accordance with the PRISMA guidelines. Seventeen randomized control trials meeting the inclusion criteria were included for analysis. Interventions with type-2 diabetic SA showed significant improvements in HbA1c% (4/5 studies), fasting blood glucose (3/4 studies), and postprandial glucose (2/2 studies). Interventions with at-risk/prediabetic and non-diabetic SA showed a modest change in overall outcomes, with significant change reported for post-prandial insulin (3/4 studies), BMI and weight (2/4 studies), and waist circumference (2/5 studies). These intervention studies showed modest control of risk factors particularly when the interventions included aspects of the culture and the attrition rate was lower. To be effective with South Asians, future studies need to have a culturally specific design, and a focus on both diet and physical activity.

Hypertension is a chronic non-communicable disease and a major risk factor for cardiovascular diseases, renal malfunction, disability, and premature death. One of the public health recommendations for the management of hypertension is the reduction of sodium/salt intake. There is need to develop and implement new evidence-based theoretical interventions to initiate and sustain behavior change in health education and promotion. Therefore, the quantitative cross-sectional method and design was used to investigate the adequacy of multi-theory model (MTM) constructs for the initiation and the sustenance of low sodium/salt intake behavior in hypertensive Nigerian adults. In addition, the impact of the MTM (initiation) constructs on actual salt/sodium intake was evaluated to validate self-reported behavior. A convenience sample of 149 consenting Nigerian adults with hypertension and of ages 20 to 60 years, self -administered the valid and reliable 39-item MTM instrument. The findings of confirmatory factor analysis showed construct validity of subscales for the initiation and sustenance model. All items loading for the two models were significant, p < 0.001. Multivariate regression analysis revealed 40.6% of the variance in initiating the consumption of low salt diets explained by advantages outweighing disadvantages, behavioral confidence, and changes in physical environment. About 41.8 % of the variance to sustain the intake of low salt diet was explained by emotional transformation, practice for change, and changes in social environment. The results justified the predictive role of MTM and adequacy of its utility to build evidence-based health education programs and interventions to address the health need of people with hypertension and contribute to social change in the country.

Weight gain due to poor diet and lack of exercise is responsible for over 300,000 deaths each year (U.S. Department of Health and Human Services, 2010). Obese adults have an increased risk for serious health conditions including high blood pressure and cholesterol, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, sleep apnea, respiratory problems, and certain cancers (National Cancer Institute, 2012). Participation in exercise can help control weight, strengthen muscles and bones, and reduce the incidence of cardiac events, stroke, hypertension, type 2 diabetes, colon and breast cancers, osteoporotic fractures, gallbladder disease, obesity, depression, anxiety, and delay mortality (ACSM, 2009). The purpose of this study was to determine the effectiveness of exercise participation during weight loss on a high protein-low carbohydrate diet plan during a 12-week span in females aged 15 to 25 years. Specifically, this research study was a comparison of markers of health such as weight, fat mass, percent body fat, and fat-free mass in females who consistently exercised during the diet (Exercisers) from those who did not participate in consistent exercise (Non- Exercisers). The population in this study was selected due to the transition from high school to college being a critical period because it is associated with many identity choices and lifestyle changes that can lead to weight gain (Anderson, Shapiro, & Lundgren, 2003). The data indicate participation in regular exercise, while consuming a high protein-low carbohydrate diet plan, increases the loss of body weight, fat mass, and percent body fat when compared to participating in the diet plan alone. There was no significant difference in fat-free mass reduction between the groups. One implication for practice is recommending moderate to vigorous exercise for a minimum of 30 minutes at a time, totaling a minimum of 150 minutes per week, for females trying to achieve weight loss. Based from the results of this research study, in order to achieve a greater amount of body weight, fat mass, and percent body fat reduction one should consider incorporating exercise participation and high protein-low carbohydrate dieting into their weight loss plan.

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (RCAP) and length (LCAP) would be greater in male rats. Male (n=4) and female (n=4) with intact kidneys and UNX (n=4 males, n=4 females) provided a 0.4% NaCl diet and water ad libitum. Kidneys were perfusion-fixed, the left kidney was excised, and a 3 mm transverse section through the midline of the kidney was selected for further processing. Multiple 1 mm3 cubes were randomly excised from the left, middle, and right regions of the outer cortex, embedded in EPONTM, sectioned (1 μm), and stained with toluidine blue. Four glomeruli from each region were randomly selected for stereological analysis. Glomerular tuft volume (VG), RCAP, and LCAP were assessed. In rats with intact kidneys, no significant sex differences were observed in VG, RCAP, or LCAP. VG, RCAP, and LCAP were significant greater in both male and female rats with UNX vs. respective rats with intact kidneys. In rats with UNX, males exhibited a significantly greater VG and LCAP, but not RCAP, as compared to females despite no significant differences in relative kidney weight. These data indicate that males exhibit greater compensatory increases in LCAP following UNX. The greater capillary length may lead to reduced podocyte density, a well-known mechanism that increases the susceptibility to CKD progression.

Current research shows moderate alcohol consumption is associated with decreased risk of diabetes and excessive consumption or binge drinking can cause insulin resistance and diabetes. In 2010, diabetes was the seventh leading cause of death in the United Statesand was responsible for significant health complications: blindness, kidney failure, and limb amputations, and is a large national economic burden. Fasting blood glucose (FBG) is a tool used to help diagnose diabetes. Abnormally high FBG, ≥100 mg/dl, is indicative of diabetes and pre-diabetes. Few studies have observed diabetic prevalence among young adults or college students. Studying young adults can help provide added information about early risk factors for diabetes and pre-diabetes, facilitating public health efforts to stem the rising tide of the diabetes epidemic. This study aimed to research the associations between alcohol consumption (numbers of days alcohol consumed in the past month and binge alcohol consumption in the past month) and FBG in a college population as part of the FLASH cohort study. FBG levels were measured in 141 young adult participants and alcohol consumption was determined by self report. Other individual-level characteristics and potential confounding variables were also collected. The association between alcohol consumption and FBG followed a J-shaped curve whereby students who reported drinking 6-8 days within the last 30 days showed significantly lower FBG levels than those who did not drink and those who consumed alcohol on nine or more days (p=0.04). Binge drinking did not have a significant association with FBG (p=0.4). Sex and body mass index were also significantly associated with FBG. In conclusion, moderate frequency of alcohol consumption is found to have an inverse relationship with FBG and excessive drinking can reverse these effects.

As the prevalence of cardiovascular diseases continues to exponentially grow in populations across the globe, the necessity of determining underlying factors, effective methods of diagnoses, and universally available preventive measures also grows. Early detection of endothelial dysfunction, a proven precursor of cardiovascular diseases, can be extremely impactful in encouraging preventative measures and early intervention before medical conditions become chronic. In recent years, ice plunging, a form of cryotherapy involving full body immersion in cold water, has gained popularity within circles of fitness and health practitioners, gaining the interest of people of all backgrounds. Certain parallels observed between the human physiological response to cold exposure and endothelial function encourage further study of the effects of ice plunging on cardiovascular health. Calibrated cuff plethysmography is a promising method of reflecting on endothelial function by measuring arterial compliance of select blood vessels. In this study, a calibrated cuff plethysmography device was built and tested for efficiency as it was used to measure compliance and cross-sectional area of the brachial artery of 14 participants 30 minutes before, immediately after, and 30 minutes after a 5-minute cold plunge in a temperature of 10°C - 15°C. Results found some significant differences between baseline measurements recorded immediately after the ice plunge and measurements recorded during reactive hyperemia conditions at normal body temperature but did not conclude that 5-minute cold-water immersion intervention had a significant impact on arterial compliance or area overall since this was a short term experiment with only acute intervention methods. The device used was concluded to effectively measure arterial compliance and area.
