RESUMO

OBJECTIVE: To describe food and beverage provisions by Faith Communities from one denomination in association with events for children. DESIGN, SAMPLE AND MEASURES: Foods and beverages provided at 32 child-focused activities were documented using direct observation methodology and analyzed for contribution to food groups and per serving energy, fat, saturated fat, sugar, and sodium contents. RESULTS: Main dishes were mostly (71%) convenience/casserole-type foods, and averaged 962 mg sodium and 436 kcal, with 36% of energy from fat and 14% as saturated fat. Cheese was the main source of dairy products. Grain-based side dishes, provided at 29% of meals, included white rice, pasta, and bread. Non-starchy vegetables were provided at three (29%) meals. Fruits were served at six events. Desserts, served at 75% of events, contained 41% of energy from fat, with 17% as saturated fat, and 22 g of added sugar. Snack chips, provided at 31% of events, contributed 165 kcal mostly from fat and 243 mg of sodium. Sugar-sweetened beverages, served at 71% of events, contributed 28 g of added sugar. CONCLUSIONS: This pilot investigation identified areas for improvements in the nutritional quality of foods/beverages served at faith community child-focused events and aligns with expanding public health efforts to improve child nutrition beyond traditional settings.

RESUMO

The objective of this pilot study was to evaluate a 6-month exercise program completed by 10 older Caribbean Americans. Assessments were done at baseline and 3 and 6 months, and included walks on an instrumented mat at preferred speed, and during street crossing simulations with regular (10 s) and reduced time (5 s). There were no significant differences on preferred walking speed over time. Differences between the street crossing conditions were found only at 6 months. Significant changes over time among the assessments were found only during street crossing with reduced time. Street crossing with reduced time was the only walking condition sensitive to capture changes associated with participating in the exercise program. There was a significant increase in dorsiflexion strength overtime. At 6 months it was significantly higher than at baseline and 3 months. The program was feasible, acceptable, and had some positive effects on walking, knee flexion, and dorsiflexion strength.

RESUMO

OBJECTIVE: To explore the food culture within faith communities (FC) in order to examine the consumption of away-from-home foods, and to provide an evidence base for the future development of healthy away-from-home meal initiatives though FCs. DESIGN AND SAMPLE: A qualitative descriptive design informed by an ethnographic method of free listing was utilized. A purposive sample of 34 FC leaders from seven distinct FCs participated in this study. RESULTS: The top five salience scores for five research questions are considered in detail. Of note, food is provided at multiple FC events including at worship time and Bible or group study, but also as part of school, youth programming, and special events. The purposes of serving food were reported to be not only for modes of entertainment and fellowship but also for promoting attendance and providing basic nutrition needs. CONCLUSIONS: Professionals practicing in public health, faith community nursing, or in community health nursing are apt to engage in focused dialogues regarding the multidimensional health problem of childhood obesity. This research study directs nurses to consider food culture as a dimension of importance, especially within FCs. Appreciating FC food culture is important because many families engage in the settings for years, decades, and possibly a life span.

RESUMO

The prevalence of dementia is growing as the population and longevity increase. Caregivers of adults with dementia report stress and fatigue and often neglect their health. They also indicate the need for information to address health-related issues, including nutritional problems, of their family members with dementia (FMWD). This study examined the impact of coaching to improve family caregiver (FCG) stress and well-being and to increase the protein intake of both FCGs and their FMWD. All participants received nutrition education including a protein prescription (1.2 g/kg body weight/day) and FCGs received stress-reduction materials. Coached-group randomized participants also received weekly diet coaching and stress-reduction coaching. At baseline and 8 weeks, anthropometrics, a mini-nutritional assessment questionnaire, and diet (protein intake) were assessed in FCGs and FMWD; well-being, fatigue and strain were assessed in FCGs. Repeated two words measures analysis of variance and Fisher's exact tests examined within group and intervention effects. Twenty-five FCGs (13 coached group, 12 not-coached group) and 23 FMWD (12 coached group, 11 not-coached group) completed the study. No significant differences were found between coached and not-coached FCGs and FMWD at baseline. After 8- weeks, FCGs' protein intake significantly increased from 1.00 ± 0.17 to 1.35 ± 0.23 g/kg/body weight in the coached group and from 0.91 ± 0.19 to 1.01 ± 0.33 g/kg/body weight in the not-coached group; there was also an intervention effect (p=.01, η2 = .24). The percentage of FCGs with baseline protein intake less than prescription guidelines and with an end-of-study protein intake meeting/exceeding the prescription significantly differed, with 60% of coached FCGs versus 10% of not coached FCGs meeting the prescription. No intervention effects were shown for protein intake in FMWD or for well-being, fatigue or strain among FCGs. Diet coaching with nutrition education successfully assisted FCGs with improving their protein intake versus nutrition education alone.

RESUMO

Obesity and high body fat percentages are a major public health issue. The percentage of obese and overweight Americans has increased over the past 30 years. On average, overweight individuals with higher percent body fat than normal weight individuals are at increased risk for numerous negative outcomes both physically and mentally. A prime time to investigate changes in body composition and associated psychological influences on decision making is during the emerging adulthood period. The first few years of college are a time when adolescents begin to regulate for themselves their own eating behaviors. Previous research shows that freshmen gain weight and increase in percent body fat during their first year of college. The current study addresses the limitations of previous research by investigating (1) individual growth in percent body fat over a longer period of time in college than previous available research and (2) important psychological and sex differences in this growth. This study measures percent body fat across the first 3 years of college at 8 time points for 542 undergraduates (351 females, 65 %; 191 males, 35 %). Longitudinal data analysis was conducted to identify changes in percent body fat, psychological predictors of those changes, and how changes differ for males and females. Our study found that significant increases exist in percent body fat during undergraduates' college years and that change differs for males and females. In addition, through the use of nested hierarchical models, eating regulation style (autonomous or controlled regulation), appearance schema (self-evaluative salience or motivational salience), and body satisfaction were identified as influential predictors of change in percent body fat. For example, young females, who do not feel in control of their physical appearance yet spend a great deal of time maintaining their appearance, have the highest initial body fat percentage and the steepest increase in percent body fat. Overall, males and females with high autonomous regulation and high motivational salience are likely to maintain (instead of increase) percent body fat over the college years. Knowing the influence of these predictors can be useful for promoting health and intervening with young adults in the college setting and other emerging adults who are not enrolled in postsecondary institutions.

RESUMO

Sufficient dietary protein intake is vital to maintaining muscle health with aging. Yet protein intake among adults is often inadequate. This study's main objective was to examine the impact of nutrition education (NE) and a per-meal protein prescription (PRx) with versus without diet coaching on protein intake. A secondary objective examined its effects on muscle health. Participants included 53 women, age 45-64 years. All participants received NE and PRx; those randomized to coached-group received 10-weeks of diet coaching. Assessments included: protein intake at baseline, weeks 4 and 12 and muscle health (muscle mass, grip strength, five-chair rise test, 4 mgait speed test). The Chi-square test examined percentages of participants meeting PRx between groups. Repeated measures analysis of variance assessed within group and intervention effects on protein intake and muscle health parameters. Protein intake (g/kg body weight) increased (p < 0.001): not-coached (n = 28) 0.8 ± 0.2 to 1.2 ± 0.3 and coached (n = 25) 1.0 ± 0.2 to 1.4 ± 0.3 with no significant difference between groups. A greater percentage of coached-group participants met (p = 0.04) breakfast (72%) and met (p < 0.001) three-meal (76%) PRx versus not-coached participants (25% and 53%, respectively). Participants in both groups exhibited significantly (p < 0.001) improved times for the five-chair rise test and 4 mgait speed test. Diet coaching in conjunction with a PRx and NE should be considered to assist individuals in improving protein intake through self-selection of protein-rich foods.

RESUMO

Physical activity is important for healthy aging, but few older adults achieve the goal of 150 min per week of moderate activity. The purpose of this study was to employ a robust statistical approach in the analysis of the factors related to physical activity in a diverse sample of older adults. A secondary analysis of factors associated with calculated MET-h/week was conducted in a sample of 601 African Americans, Afro-Caribbeans, European Americans, and Hispanic Americans age 59 to 96 living independently in the community. Age, education, social network, pain, and depression were the five variables that accounted for a statistically significant proportion of unique variance in the model. The strongest correlation to total MET-h/week was with depression. Directionality of the relationship between these variables and physical activity is complex: while pain and depression can reduce physical activity, activity may also help to reduce pain and depression. Additionally, of note is that many of these factors may be modified, calling for the design and testing of individual, group, and community level interventions to increase physical activity in the older population.

RESUMO

OBJECTIVE: Changes in body weight, composition, and shape were investigated in male and female college students between the freshman and sophomore years. METHODS: Changes in weight, body mass index (BMI), percent and absolute body fat and fat-free mass (via bioelectrical impedance), and waist circumference (via body scans) were assessed over the freshman and sophomore years (2007-2009) among 120 students attending a Southern public university. RESULTS: Weight (2.5 and 1.7 lbs) and BMI gains (0.3 and 0.3 kg/m(2)) did not significantly differ between the freshman and sophomore years, respectively. Significantly more percent body fat and fat mass were gained during the freshman (1.9% and 3.3 lbs, respectively) than the sophomore year (0.0% and 0.6 lbs, respectively). Females lost significantly more fat-free mass during the freshman (-0.8 lb) than during the sophomore year (1.0 lb). Changes in waist circumference and weight were significantly correlated. Increases in the percentages of females classified as overweight and with unhealthy body fat amounts and waist circumferences were observed. CONCLUSION: While the sophomore year was characterized by slightly healthier body composition changes than the freshman year, the gains in weight, fat mass, and waist circumference measurements suggest increased health risks for many college females.

RESUMO

Over 80% of adults in the US fail to meet the ≥150 min weekly physical activity guideline; 40% age ≥ 75 are entirely inactive. The study purpose was to understand the reasons why community-dwelling older adults (age ≥ 60) from diverse backgrounds increase, sustain, or decline in their physical activity levels over time. Sixty-two older adults were interviewed. Two-thirds of the African Americans, 57% of the Afro-Caribbeans, and 50% of the European Americans reported being less active than 2-3 years ago. Reasons for activity decline included health issues (e.g., pain, shortness of breath), lack of time, interest, or motivation. Reasons for sustaining or increasing activity levels included meeting personal goals, having a purpose for remaining active, or feeling better when active (e.g., it is important to keep moving, good for the joints, going on a cruise). Themes identified were pride in maintaining activity, goal-driven activity, pushing oneself to get past pain or fatigue, and some confusion between social and physical activity in participant reports. The results indicate widespread acceptance that activity is beneficial, but that knowledge alone was insufficient to maintain activity levels over time unless individuals had a goal or purpose ("means to an end") and could overcome their physical and psychological barriers to physical activity.

RESUMO

Projections indicate that the older American population will become more racially diverse in the future. Therefore, eliminating health disparities among older adults should be a public health priority. Using data from the 1999-2002 National Health and Nutrition Examination Survey, we examined the relationship between obesity, measured by BMI and waist circumference, and gait speed, a performance-based measure of physical function, in 2,285 older adults (≥60 y) in order to determine whether this relationship varies by race/ethnicity. Overweight and obesity, indicated by a BMI ≥ 25 kg/m(2) and a waist circumference in quartiles 3 (male: 102.4-109.9 cm; female: 97.3-106.3 cm) and 4 (male: 110.2-156.6 cm; female: 106.4-147.5 cm), were associated with slower gait speed in non-Hispanic Whites. Among non-Hispanic Blacks, only extreme obesity, indicated by a BMI ≥ 35 kg/m(2) and a waist circumference in quartile 4 (male: 110.2-149.6 cm; female: 106.4-137.7 cm), was associated with a slower gait speed. Among Mexican Americans, only extreme obesity, indicated by a BMI ≥ 35 kg/m(2), was associated with a slower gait speed. Thus we found the relationship between obesity and gait speed differed by race/ethnicity. The goal of eliminating health disparities in access to and quality of health care is only possible when differences in the associations between possible risk factors and physical function are identified.

RESUMO

Inadequate protein intake contributes to poor nutritional status, reduced muscle mass, strength and function, and increased mortality. Evaluating differences in protein intake and related health indicators among racial/ethnic groups enables the development of targeted interventions. This study's purpose was to determine differences in protein intake, nutritional status, and muscle strength/function among 273 older African, European, and Hispanic Americans. Protein intake, nutritional status, grip strength, timed-up-and-go (TUG), and chair stand assessments were conducted. Protein intake was significantly greater among Hispanic Americans (0.96 g/kg body weight) followed by European Americans (0.83 g/kg body weight), and African Americans (0.64 g/kg body weight). Intakes by all groups were below recommendations. Low nutritional status, grip strength, chair rise, and TUG scores were observed in African Americans and European American females and were consistent with lower protein intakes. Results show significant differences among the groups and the need for interventions to improve diet and physical health.

RESUMO

The aim of this article is to provide clarity of the concept of health habit. Using Walker and Avant's (1983; 2010) method for conducting a concept analysis, the authors identify the attributes and characteristics of health habit, its theoretical and practical application to nursing, and sample cases to further illustrate the concept. Empirical and conceptual literature was used to inform this concept analysis. Articles and one book from 1977 to 2014 were reviewed from PsycINFO, Medline, Cumulative Index to Nursing Health Literature (CINAHL), Science Direct, EBSCOhost and Web of Science. Offering a clear definition and conceptual model of health habit provide the foundation to identify/develop appropriate measures of the concept and guide further investigation of understanding the development and sustainability of healthy habits. Additional research is needed to test the conceptual relationships between health habits and outcome variables as they apply to different groups across the age continuum.

RESUMO

The interactive role of eating regulation and perceived stress on weight-related outcomes was examined among 319 sophomore year college students (110 males and 209 females). Moderated regressions were used to examine interactions between stress and eating regulation on study outcomes including body mass index (BMI) and body fat. Eating regulation moderated associations between stress and BMI and body fat outcomes. Students reporting high perceived stress, high autonomous eating regulation, low controlled regulation, and low amotivation exhibited higher outcomes (BMI and body fat) than those with similar eating regulation but lower perceived stress. Students with lower autonomous eating regulation and higher controlled regulation had no differences in study outcomes across levels of stress. College students who regulate their eating behaviours for health reasons (specifically showing autonomous regulation) exhibit higher BMI and body fat when they report higher levels of perceived stress. Health promotion programs for college students need to target education efforts towards stress reduction and healthy eating behaviours.

RESUMO

BACKGROUND: Metabolic rate is known to rise above basal levels after eating, especially following protein consumption. Yet, this postprandial rise in metabolism appears to vary among individuals. This study examined changes in energy expenditure in response to ingestion of a high protein, high fat (HPHF) meal versus an isocaloric high protein, low fat (HPLF) meal in underweight, normal weight, or overweight females (n = 21) aged 19-28 years. METHODS: Energy expenditure, measured using indirect calorimetry, was assessed before and every 30 minutes for 3.5 hours following consumption of the meals on two separate occasions. Height and weight were measured using standard techniques. Body composition was measured using bioelectrical impedance analysis. RESULTS: Significant positive correlations were found between body mass index (BMI) and baseline metabolic rate (MR) (r = 0.539; p = 0.017), between body weight and baseline MR (r = 0.567; p = 0.011), between BMI and average total change in MR (r = 0.591; p = 0.008), and between body weight and average total change in MR (r = 0.464; p = 0.045). Metabolic rate (kcal/min) was significantly higher in the overweight group than the normal weight group, which was significantly higher than the underweight group across all times and treatments. However, when metabolic rate was expressed per kg fat free mass (ffm), no significant difference was found in postprandial energy expenditure between the overweight and normal groups. Changes in MR (kcal/min and kcal/min/kg ffm) from the baseline rate did not significantly differ in the underweight (n = 3) or in the overweight subjects (n = 5) following consumption of either meal at any time. Changes in MR (kcal/min and kcal/min/kg ffm) from baseline were significantly higher in normal weight subjects (n = 11) across all times following consumption of the HPHF meal versus the HPLF meal. CONCLUSION: There is no diet-induced thermogenic advantage between the HPHF and HPLF meals in overweight and underweight subjects. In contrast, in normal weight subjects, ingestion of a HPHF meal significantly increases MR (69.3 kcal/3.5 hr) versus consumption of a HPLF meal and provides a short-term metabolic advantage.

RESUMO

Iron status was assessed in 70 female athletes aged 18-25 yr participating in collegiate cross-country track, tennis, softball, swimming, soccer, basketball, and gymnastics. No significant differences in mean hemoglobin, hematocrit, serum iron, total iron-binding capacity, transferrin saturation, and ferritin were found among teams. The mean concentrations of each parameter for each of the teams were within the normal ranges. However, several athletes from different sports had suboptimal iron status indexes. Of 17 athletes with a serum ferritin concentration < or = 15 microg/L, 8 (4 freshmen, 2 sophomores, 2 unknown) also exhibited low serum iron concentrations (< 60 microg/dL) and low transferrin saturation (< 16%). Thirteen (6 freshmen, 3 sophomores, 2 juniors, 2 seniors) of 51 (25%) athletes failed to consume two-thirds of the Recommended Dietary Allowance for iron and exhibited suboptimal serum concentrations of ferritin, iron, and/or transferrin saturation. Of nine athletes taking iron supplements, one exhibited suboptimal iron status. In summary, nonanemic iron depletion was present among female collegiate athletes involved in many different sports and in all years of participation (freshmen, sophomore, junior, and senior athletes). Female athletes should continue to be individually and routinely evaluated for nutritional deficiencies throughout their collegiate athletic careers.

RESUMO

Given the many well-documented relationships between diet and health, growing medical care expenses for those incarcerated, and limited information on foods served in correctional facilities, this study examined the nutritional adequacy of a 28-day cycle menu used in a large county jail in Georgia. When compared with Dietary Reference Intakes, provisions of energy (female inmates only), sodium, saturated fat, and cholesterol exceeded recommendations. Magnesium, potassium, and vitamins A, D, and E met less than two thirds of recommendations. Compared with MyPlate recommendations, grains were overrepresented, while vegetables, fruits, and dairy were underrepresented in the menu. Small menu changes could improve the menu's nutrient content and potentially increase inmates' health and well-being.

RESUMO

Oxidative damage, as indicated by protein carbonyl and lipid hydroperoxide concentrations, was assessed in the plasma of college-aged females with adequate iron status and with non-anemic iron deficiency before and after eight weeks of iron supplementation. At baseline, the mean serum ferritin, iron, transferrin saturation, and total iron binding capacity of the iron deficient group (n = 13) was significantly different from the iron adequate controls (n = 24). Mean plasma lipid hydroperoxide and protein carbonyl concentrations did not differ between groups at baseline. Following eight weeks of iron supplementation, the mean serum ferritin, iron, and transferrin saturation significantly increased and the total iron binding capacity significantly decreased in the iron deficient group. No significant differences in plasma lipid hydroperoxide or protein carbonyl concentrations were found between groups at the end of the study period. When plasma lipid hydroperoxide and protein carbonyl concentrations of subjects within groups were compared at the start versus at the end of the study, no significant differences were found for either group. Neither non-anemic iron deficiency nor its treatment with oral iron supplements is associated with oxidative damage in the plasma of college-aged females.

RESUMO

The effects of a 30 mg/day beta-carotene supplement for 60 days on blood cell and serum antioxidant enzymes and selenium concentrations were examined in healthy adults. Serum beta-carotene concentrations increased significantly (P < 0.05) in response to supplementation. Forty percent of subjects exhibited hypercarotenemia of the skin after 30 days. There were no changes in the activity of red blood cell or leukocyte catalase activity, red blood cell copper,zinc-dependent superoxide dismutase activity or serum myeloperoxidase concentration in response to beta-carotene supplementation. Leukocyte superoxide dismutase activity decreased significantly (P < 0.05) at 30 and 60 days compared to baseline. Serum glutathione peroxidase concentration decreased significantly (P < 0.05) between baseline and days 45 and 60 of supplementation. Serum selenium and blood hemoglobin concentrations did not change during the study. Supplemental beta-carotene may alter the antioxidant capacity of plasma and/or blood cells in vivo.

RESUMO

Treatment of galactosemia requires a galactose-restricted diet. Although meats are not traditionally thought of as a dietary carbohydrate source, small amounts may be present in free form and/or bound to proteins or lipids. The purpose of this study was to determine the free and bound galactose contents of baby food meats. Galactose was assayed using high-performance liquid chromatography. The free galactose content of baby food meats ranged from 0 to 0.031 mg/100 g. No statistically significant differences in free galactose content were found among the meats. Bound galactose was found in all analyzed baby food meats, ranging from 0.065 to 0.148 mg/100 g. The mean galactose content of BeechNut chicken (St. Louis, MO) was significantly less than that found in Gerber (Fremont, MI) and Heinz (Pittsburgh, PA) brands of chicken, beef, and turkey, and Gerber lamb and veal. Based on current recommendations, all examined baby food meats would be acceptable for infants with galactosemia.
