Larger people generally have more muscle mass and are stronger than smaller people. Muscular strength usually decreases with age, possibly as a function of increases in body fat percentage. However, the effect of age, body fat, and lean mass on peak muscular strength or muscular fatigue is not clear. This was an observational study to determine: a) the relationship of fat mass (FM) and fat free mass (FFM) to peak knee extensor strength and fatigue in young (Y) and middle-aged (MA) women, and b) to determine differences in peak torque between Y and MA women. Participants included 132 women from two age cohorts (Y: 18-33 yrs, n = 70 and MA: 45-65 yrs, n = 62). Data from the MA cohort were collected as part of a previous study and combined with data from the Y group. Both cohorts completed physical activity questionnaires and were measured for body fat using bioelectrical impedance analysis. Both cohorts used identical procedures and machinery to assess isokinetic knee extensor peak torque (PT) at 60°/sec and to determine fatigue index (FI). FI was calculated as the percent decline of PT during 50 maximal repetitions at 240°/sec. Data were assessed for normality, and appropriate Pearson or Spearman correlations were used to compare PT and FI with body composition variables. A one-way ANOVA was used to examine differences in PT and body composition indices between age groups. In Y, FFM and FM were strongly correlated with peak torque. The correlation of FM to PT disappeared when controlling for FFM. There were no significant correlations between FFM or FM and PT in MA. PT was negatively correlated with FI in the combined groups. PT normalized for body mass and FFM were similar between age groups, but decreased with increasing size. In conclusion, PT was positively related to FFM in the combined age groups. Higher FM was not detrimental to absolute PT in Y or MA, but was detrimental to relative PT in both groups. These data suggest that perhaps FM may attenuate the normal relationship between PT and body mass.

Among its many roles in the body, ascorbic acid functions as a cofactor in carnitine and catecholamine synthesis, metabolites involved in fat oxidation and mood regulation, respectively. Given that fat oxidation and mood affect one's feelings of vigor, I hypothesized that those with lower levels of plasma ascorbic acid would be less likely to exercise at high levels than individuals with adequate or high levels of vitamin C. To test this, I conducted a double-blind, placebo-controlled intervention. A group of healthy, non-smoking males between the ages of 18 and 40 were put on a vitamin C-restricted diet for two weeks and then randomized to a control group that received placebo capsules for six weeks or an intervention group that received 500 mg of vitamin C daily for six weeks. The men were restricted from eating foods high in vitamin C, instructed to wear a pedometer daily and to record their step counts, and to take a pill daily (either the placebo or vitamin C supplement). Unexpectedly, the subjects receiving the intervention had lower step counts than the control group; the control group, rather than the vitamin C group, significantly (p=0.017) increased their steps at week 8 compared to week 2. However, I also estimated daily Metabolic Equivalent Tasks (METs), and subjects receiving the placebo had lower MET outputs than subjects receiving vitamin C at the end of the trial, in spite of having higher step counts. This means the intensity of their activity was higher, based on METs expenditure. Additionally, depression scores (POMS-D) as measured by the Profile of Mood States (POMS) questionnaire were significantly higher (p=0.041) among subjects receiving the placebo at the end of the study. These latter results are consistent with my expectations that subjects with higher levels of plasma vitamin C would have improved mood and higher energy output than subjects with low levels of vitamin C.

Background
Weight gain during the childbearing years and failure to lose pregnancy weight after birth contribute to the development of obesity in postpartum Latinas.
Methods
Madres para la Salud [Mothers for Health] was a 12-month, randomized controlled trial exploring a social support intervention with moderate-intensity physical activity (PA) seeking to effect changes in body fat, fat tissue inflammation, and depression symptoms in sedentary postpartum Latinas. This report describes the efficacy of the Madres intervention.
Results
The results show that while social support increased during the active intervention delivery, it declined to pre-intervention levels by the end of the intervention. There were significant achievements in aerobic and total steps across the 12 months of the intervention, and declines in body adiposity assessed with bioelectric impedance.
Conclusions
Social support from family and friends mediated increases in aerobic PA resulting in decrease in percent body fat.

Despite their low cost and high nutrient density, the contribution of eggs to nutrient intake and dietary quality among Mexican-American postpartum women has not been evaluated. Nutrient intake and dietary quality, as assessed by the Healthy Eating Index 2010 (HEI-2010), were measured in habitually sedentary overweight/obese (body mass index (BMI) = 29.7 ± 3.5 kg/m[superscript 2]) Mexican-American postpartum women (28 ± 6 years) and compared between egg consumers (n = 82; any egg intake reported in at least one of three 24-h dietary recalls) and non-consumers (n = 57). Egg consumers had greater intake of energy (+808 kJ (193 kcal) or 14%; p = 0.033), protein (+9 g or 17%; p = 0.031), total fat (+9 g or 19%; p = 0.039), monounsaturated fat (+4 g or 24%; p = 0.020), and several micronutrients than non-consumers. Regarding HEI-2010 scores, egg consumers had a greater total protein foods score than non-consumers (4.7 ± 0.7 vs. 4.3 ± 1.0; p = 0.004), and trends for greater total fruit (2.4 ± 1.8 vs. 1.9 ± 1.7; p = 0.070) and the total composite HEI-2010 score (56.4 ± 12.6 vs. 52.3 ± 14.4; p = 0.082). Findings suggest that egg intake could contribute to greater nutrient intake and improved dietary quality among postpartum Mexican-American women. Because of greater energy intake among egg consumers, recommendations for overweight/obese individuals should include avoiding excessive energy intake and incorporating eggs to a nutrient-dense, fiber-rich dietary pattern.

Almost sixty percent of adults within the United States are in a married or committed, cohabiting relationship. This study sought to examine the trajectory of relationship satisfaction over 14 consecutive days employing an ecological momentary assessment (EMA) method. Daily reports of relationship satisfaction were collected via a smartphone application developed from the LifeData platform. Phone-based interview questions posed one week after the 14-day EMA period afforded evaluation of usability and acceptability, in preparation for a much larger study of couples coping with cancer. Twenty-seven adults in a married or committed, cohabitating relationship served as participants, recruited from researchmatch.org. (These individuals were not coping with cancer.) Participants received a smartphone notification between 7:30pm and 8:30pm each day, with 45 minutes to begin recording their responses. A single item from the Dyadic Adjustment Scale (item #31) was used to assess relationship satisfaction. Findings revealed a marginally significant increase in satisfaction over the course of 14 days (b = 0.04, t = 1.85, p = .077). In addition, an intraclass correlation (ICC) value of 0.59 indicated larger between-person variability than within-person variability, suggesting that satisfaction varies more from one individual to another than it does within individuals over time. Finally, plots of mean relationship satisfaction by the standard deviation of relationship satisfaction showed lower variability in day-to-day satisfaction among those who were on average more satisfied with their relationship compared to those who were on average less satisfied. Feedback regarding convenience and ease of the application indicated favorable attitudes towards smartphone-based data collection.

The purpose of the study was to explore students' writing abilities throughout the online RN-BSN program at a large urban university in the Southwest. The aims of the study were: 1) explore how students' writing abilities, confidence in writing, and ability to locate resources change throughout the online RN-BSN program, 2) identify which aspects of writing students consider to be their strengths and/or challenges, and 3) explore which factors predict how well students write, their confidence in writing, and their ability to locate resources. After obtaining IRB approval, an invitation to participate in the study was sent to students enrolled in four different courses within the RN-BSN program. Students who chose to participate completed a 16-item questionnaire in which they rated their writing abilities, confidences, and skills, indicated strengths and challenges in their writing, and skills in locating evidence-based resources. An improvement was noted in students' self-rated academic writing confidence, professional writing confidence, internet reference skills, and library reference skills. The number of years as a registered nurse predicted overall writing ability and academic writing confidence.

Physician's cultural competence is important in healthcare because it helps improve quality of care as well as address healthcare disparities among minorities. Additionally, it positively correlates with patient satisfaction, which has been shown to increase treatment adherence and improve medical outcomes. This study investigated the effect of physician's cultural competence on patient satisfaction in a Latino population and how these compared to a European-American population. Physician's Cultural Competence for Patient Satisfaction (PCCPS) scale developed by Dr. Ahmed was utilized in this study. The PCCPS scale deconstructed physician's cultural competence into five subcategories: Macro-cultural, Proxemics/Chronemics, Language, Patient-centered Cultural Competence, and Patient Satisfaction. This scale and various demographic questions were incorporated into a survey that was distributed amongst participating patients. Gathered data was analyzed to determine which demographic factors and subcategories of physician's cultural competence were more relevant or important when interacting with patients that have distinct cultural backgrounds, such as Latino and European-American. Findings from this study will add to building a foundation of evidence in health care that advocates for a more holistic approach to medicine and incorporates cultural competence as an important determinant to predicting health care outcomes.

Purpose: The purpose of this study is to examine perceptions of medical-surgical nurses of alcohol-abusing patients admitted to an acute care facility Background: Studies report that many nurses have negative feelings about substance-abusing patients (Neville & Roan, 2014). It has been found nurses report a lack of knowledge about substance abuse disorders, as well as a view that substance abusing patients are more emotionally challenging and dangerous, often leading to decreased motivation and lower levels of job satisfaction (van Boekel, Brouwers, van Weeghel & Garrestsen, 2013). However, studies have found that additional education can positively impact nurses' perceptions (Arthur, 2001). Methods/Approach: This study is a descriptive design using a 17-question 2-part survey. The first part of the survey includes seven demographic questions pertaining to the participants' characteristics and experiences. The second part of the survey is adapted from the Short Alcohol and Alcohol Problems Perception Questionnaire (SAAPPQ), a valid and reliable instrument used to assess healthcare providers' attitudes toward working with alcohol-abusing patients. Results: Eighty four medical-surgical nurses participated in the study. Over half reported having four hours or less of continuing education on alcohol abuse disorder. Regression analyses identified positive relationships between factors, particularly continuing education, on perceptions of alcohol-abusing patients. Conclusions/Implications: Results of this study can be used to determine what factors contribute to nurses' perceptions of alcohol-abusing patients in the medical-surgical unit, therefore aiding in identifying and developing effective policies, protocols, and interventions aimed at improving quality of patient care in this specific patient population.

This study aims to examine children’s fruit, vegetable, and added sugar consumption relative to the Dietary Guidelines for Americans and the American Heart Association’s recommendations, as well as to compare children’s reported consumption with parental perception of the child’s overall diet quality. Data were drawn from 2 independent, cross sectional panels (2009–10 and 2014–15) of the New Jersey Child Health Study. The analytical sample included 2229 households located in five New Jersey cities. Daily consumption of fruit (cups), vegetables (cups), and added sugars (teaspoons) for all children (3–18 years old) were based on parent reports. Multivariate linear regression analyses estimated children’s adjusted fruit, vegetable, and added sugar consumption across parents’ perception categories (Disagree; Somewhat Agree; and Strongly Agree that their child eats healthy). Although only a small proportion of children meet recommendations, the majority of parents strongly agreed that their child ate healthy. Nonetheless, significant differences, in the expected direction, were observed in vegetable and fruit consumption (but not sugar) across parental perceptional categories for most age/sex groups. Dietary interventions tailored to parents should include specific quantity and serving-size information for fruit and vegetable recommendations, based on their child’s age/sex, and highlight sources of added sugar and their sugar content.

Disparities in healthy food access are well documented in cross-sectional studies in communities across the United States. However, longitudinal studies examining changes in food environments within various neighborhood contexts are scarce. In a sample of 142 census tracts in four low-income, high-minority cities in New Jersey, United States, we examined the availability of different types of food stores by census tract characteristics over time (2009–2017). Outlets were classified as supermarkets, small grocery stores, convenience stores, and pharmacies using multiple sources of data and a rigorous protocol. Census tracts were categorized by median household income and race/ethnicity of the population each year. Significant declines were observed in convenience store prevalence in lower- and medium-income and majority black tracts (p for trend: 0.004, 0.031, and 0.006 respectively), while a slight increase was observed in the prevalence of supermarkets in medium-income tracts (p for trend: 0.059). The decline in prevalence of convenience stores in lower-income and minority neighborhoods is likely attributable to declining incomes in these already poor communities. Compared to non-Hispanic neighborhoods, Hispanic communities had a higher prevalence of small groceries and convenience stores. This higher prevalence of smaller stores, coupled with shopping practices of Hispanic consumers, suggests that efforts to upgrade smaller stores in Hispanic communities may be more sustainable.
