Drug metabolism and personalized therapy. 2020;(2)
Abstract
Objectives Self-esteem is the degree to which the qualities and characteristics contained in one's self-concept are perceived to be positive. The aim of this study was to evaluate the self-esteem scores in phenylketonuria (PKU) patients on "strict", "loos" and "off diet". Sixty PKU patients were divided in three equal groups. Methods Group a: "on strict", group b: "on loos" and group c: "off diet". A special questionnaire for self-esteem scores was created for these patients. Results Before psychological support, group a patients demonstrated 6/20 (30%) very high self-esteem, 9/20 (45%) high and 5/25 (25%) moderate. After support 14/20 (70%) were turned to very high, 5/20 (25%) represented high except one whose degrees remained an altered. group b 4/20 (20%) were very high, 7/20 (35%) were high, 3/20 (15%) moderate and the rest of them showed low self-esteem degrees, after support, 10/20 (50%) showed very high, 5/20 (25%) became high, 3/20 (15%) turned to moderate and 2/20 (10%) remained unaltered. Group c, 1/20 (5%) were very high self-esteemed, 7/20 (35%) were high, 6/20 (30%) were moderate and 6/20 (30%) with low self-esteemed, at the end of support, 6/20 (30%) become very high, 8/20 (40%) with high, 4/20 (20.0%), moderate self-esteem whereas the rest were unaltered. Conclusions Very high and high self-esteem degrees were demonstrated in patients who follow their PKU diet. Moderate and low self-esteem degrees were predominantly found in patients on loos and or off diet. Psychological supports commonly result in amelioration of self-esteem degrees.

Abstract
BACKGROUND Racial minority children, particularly from low-income households, are at risk for obesity. Family meals have a protective effect on child nutritional health. However, the current evidence is limited in racial and socioeconomic diversity. The objective of this study was to evaluate the impact of a family meals intervention, Simple Suppers, on improvements in diet and health outcomes from baseline (T0) to post-intervention (T1) in intervention compared to waitlist control participants, and determine retention of change in outcomes among intervention participants at 10-week follow-up (T2). METHODS Simple Suppers was a 10-week family meals intervention implemented as a 2-group quasi-experimental trial. Ten 90-min lessons were delivered weekly. Data were collected at T0 and T1, and from intervention participants at T2. Participants were racially diverse 4-10 year-old children from low-income households. Setting was a faith-based community center. Main outcomes were daily servings of fruit, vegetables, and sugar-sweetened beverages and diet quality; z-scores for body mass index (BMI), waist circumference, systolic and diastolic blood pressure (BP); weight status categories; food preparation skills; and family meals (frequency of dinner, breakfast, TV viewing during meals, meals in dining area). Generalized linear mixed models (GLMMs) and mixed-effects ordinal regression models were used to assess intervention impact (T0:T1). Paired t-tests examined retention of change among intervention participants (T1:T2). RESULTS One hundred forty children enrolled and 126 completed T1 (90% retention); 71 of 87 intervention participants completed T2(79% retention). Mean (SD) age was 6.9(1.9) yr, 62% female, 60% Black, and 42% low-income. Intervention vs waitlist controls had higher food preparation skills (p < 0.001) and lower TV viewing during meals (p = 0.04) at T1.There were no group differences in dietary intake or quality or z-scores for BMI, waist circumference, or BP, however intervention versus waitlist controls experienced a greater change toward healthy weight (p = 0.04) At T2, intervention participants demonstrated a retention of improved food preparation skills. CONCLUSIONS Simple Suppers led to improvements in children's weight status, food preparation skills, and TV viewing during meals, but not diet or z-scores for BMI, waist circumference, or BP. Future research should examine the preventive effects of healthy family mealtime routines in children at greatest risk for obesity.

Abstract
Involvement of children in gardening has the potential to increase liking of fruit and vegetables (FV) and consequently, intake, but research results are mixed. School gardening led by external specialists such as the Royal Horticultural Society (RHS) could have more impact than teacher-led gardening on children's knowledge of, and attitudes towards, FV. Data from a cluster randomised controlled trial were used to compare a RHS-led school gardening intervention with a teacher-led gardening intervention amongst 7-10 year olds in 21 London schools. A short questionnaire was developed and used to identify children's knowledge and attitudes towards FV consumption before the garden intervention and 18 months afterwards. Results from multilevel regression models, both unadjusted and adjusted for baseline responses and socio-demographic factors, were reported. Attitudes to FV intake were compared between groups. Change in FV knowledge was used to predict change in FV consumption assessed using 24-hour food diaries. In comparison with the RHS-led group (n = 373), teacher-led children (n = 404) were more likely to agree they ate lots of fruit (p < 0.009) and tried new fruits (p = 0.045), but RHS-led gardening was associated with a greater increase in the total number of vegetables recognised (p = 0.031). No other differences in improvements in attitudes, or associations between change in FV recognition and intake were found. In relation to improvements in children's recognition and attitudes towards eating FV, this trial produced limited evidence that gardening activity packages led by external specialists (RHS-led) provide additional benefits over those led by teachers trained by the RHS. Indeed, the latter were potentially more effective.

Abstract
OBJECTIVE To reduce risk factors in workplace settings in low- and middle-income countries. DESIGN AND SAMPLE Workplace interventions were utilized as part of the Community Interventions for Health program, a nonrandomized, controlled study undertaken in three communities in China, India, and Mexico. Exactly, 45 industrial, 82 health and 101 school workplace settings with a target population of 15,726. Two independent cross-sectional surveys of workers were conducted at baseline and follow-up, after 18-24 months of intervention activities. MEASURES Culturally appropriate interventions to reduce tobacco use, increase physical activity, and improve dietary intake were delivered in the intervention areas. RESULTS Exactly, 12,136 adults completed surveys at baseline, and 9,786 at follow-up. In the intervention group, the prevalence of tobacco use reduced significantly in men (-6.0%, p < .001) and the proportion eating five portions of fruit and vegetables daily increased (+6.9%, p < .001) compared with the control group. There were no significant differences between the groups for changes in physical activity or prevalence of overweight. CONCLUSIONS Workplace interventions improved risk factors in China, India, and Mexico.

An experimental field study of weight salience and food choice.
Incollingo Rodriguez, AC, Finch, LE, Buss, J, Guardino, CM, Tomiyama, AJ
Appetite. 2015;:215-8
Abstract
Laboratory research has found that individuals will consume more calories and make unhealthy food choices when in the presence of an overweight individual, sometimes even regardless of what that individual is eating. This study expanded these laboratory paradigms to the field to examine how weight salience influences eating in the real world. More specifically, we tested the threshold of the effect of weight salience of food choice to see if a more subtle weight cue (e.g., images) would be sufficient to affect food choice. Attendees (N = 262) at Obesity Week 2013, a weight-salient environment, viewed slideshows containing an image of an overweight individual, an image of a thin individual, or no image (text only), and then selected from complimentary snacks. Results of ordinal logistic regression analysis showed that participants who viewed the image of the overweight individual had higher odds of selecting the higher calorie snack compared to those who viewed the image of the thin individual (OR = 1.77, 95% CI = [1.04, 3.04]), or no image (OR = 2.42, 95% CI = [1.29, 4.54]). Perceiver BMI category did not moderate the influence of image on food choice, as these results occurred regardless of participant BMI. These findings suggest that in the context of societal weight salience, weight-related cues alone may promote unhealthy eating in the general public.

The Journal of clinical endocrinology and metabolism. 2013;(12):E1901-8
Abstract
CONTEXT The pathophysiology of calcium-phosphate disturbances in diabetic (DM) kidney disease differs from that in non-DM chronic kidney disease (CKD). OBJECTIVE We compared the effect of a 6-day high-phosphate diet on serum fibroblast growth factor-23 (FGF-23) and other parameters of calcium-phosphate metabolism in DM and non-DM CKD patients. DESIGN AND SETTING This was a prospective interventional study in a research center setting. PARTICIPANTS, INTERVENTION, AND MEASURES Twenty-six nondialysis patients with stages 3-5 CKD and albuminuria less than 300 mg/g creatinine were recruited from February 2011 to November 2012 (15 DM, 11 non-DM). All patients received a high-phosphate diet (1800 mg/d) for 6 days. At baseline, day 3, and day 7 serum FGF-23, PTH, Ca, P, 25-hydroxyvitamin D, 1,25 dihydroxyvitamin D, monocyte chemoattractant protein-1, and calcium and phosphate urine excretion were measured. RESULTS In DM CKD patients, serum calcium was lower on days 3 and 7 vs baseline (P < .01, respectively), and in non-DM patients, it was unchanged. Serum phosphorus increased significantly only in non-DM patients on days 3 and 7 vs baseline (P < 0.01, respectively). Serum PTH was higher in the DM group on day 7 vs baseline (P = .04). Plasma 25-hydroxyvitamin D, 1,25 dihydroxyvitamin D, and serum monocyte chemoattractant protein-1 were unchanged in both groups. Serum FGF-23 increased in DM patients, from baseline to day 3 (58.1 ± 52.7 and 91.6 ± 71.1 pg/mL, P = .001) but later tended to decrease. In non-DM patients, there was a steady increase of FGF-23 between baseline and day 7 (75 ± 84.3 to 176 ± 197 pg/mL, P = .04). Urine phosphate excretion was significantly higher on day 7 in DM patients only (P < .05). CONCLUSIONS PTH seems to play the major role in the regulation of phosphate excretion in DM CKD. The role of FGF-23 in phosphate disposal in DM CKD remains debatable.

Abstract
OBJECTIVE To determine if localised programmes that are successful in engaging the community can add value to larger fruit and vegetable mass-media campaigns by evaluating the results of the Eat It To Beat It programme. DESIGN The Eat It To Beat It programme is a multi-strategy intervention that uses community-based education and ‘below the line’ social marketing to increase fruit and vegetable consumption in parents. This programme was evaluated by a controlled before-and-after study with repeat cross-sectional data collected via computer-assisted telephone interviews with 1403 parents before the intervention (2008) and 1401 following intervention delivery (2011). SETTING The intervention area was the Hunter region and the control area was the New England region of New South Wales, Australia. SUBJECTS Parents of primary school-aged children (Kindergarten to Year 6). RESULTS The programme achieved improvements in knowledge of recommended intakes for fruit and vegetables and some positive changes in knowledge of serving size for vegetables. Exposure to the programme resulted in a net increase of 0.5 servings of fruit and vegetables daily for those who recalled the programme compared with those who did not (P = 0.004). Increased intake of fruit and vegetables was significantly associated with increasing exposure to programme strategies. CONCLUSIONS The Eat It To Beat It programme demonstrates that an increase in consumption of fruit and vegetables can be achieved by programmes that build on the successes of larger mass-media and social-marketing campaigns.This suggests that funding for localised, community-based programmes should be increased.

Abstract
Ghrelin, an orexigenic hormone, may be involved in the etiology of obesity. African Americans (AA) experience higher obesity rates than European Americans (EA), but it is unclear whether ghrelin differs with ethnicity. This study was designed to compare ghrelin concentrations between overweight AA and EA adults in a post absorptive state, in response to a standard meal, and after 8-week habituation to diets of differing macronutrient profiles. Sixty-one overweight men and women (31 EA and 30 AA) were assigned to either a higher-carbohydrate/lower-fat diet (55% CHO, 18% PRO, 27% FAT) or a lower-carbohydrate/higher-fat diet (43% CHO, 18% PRO, 39% FAT) for 8 weeks. At baseline and week 8, participants ingested a standard liquid mixed meal. Blood was sampled before the meal and serially after ingestion to measure total ghrelin and insulin. Hunger was assessed with a visual analog scale. Composite scores for ghrelin, insulin, and hunger were calculated as area under the curve (AUC), and ghrelin suppression was calculated as the change from fasting concentration. Fasting ghrelin and ghrelin AUC were higher among EA at baseline and week 8 (p < 0.001), and these differences were not affected by diet habituation. Despite greater postprandial ghrelin suppression, EA displayed greater hunger immediately following the test meal (p < 0.05). Overweight EA displayed higher circulating ghrelin and greater ghrelin suppression compared to AA. Further study is warranted to explore the physiological basis for these ethnic differences and to determine whether they may relate to higher obesity rates among AA.

Disliked food acting as a contaminant in a sample of young children.
Brown, SD, Harris, G, Bell, L, Lines, LM
Appetite. 2012;(3):991-6
Abstract
Anecdotal evidence suggests that a disliked food can act as a contaminant to liked food during childhood. While this has been investigated in an infant sample, the current paper presents the first study to investigate this phenomenon in a sample of young children (4 years 5 months-6 years 1 month old, N=30). Children were shown a liked food at different stages of being contaminated by a disliked food. At each stage, the children were asked to rate their willingness to consume the liked food on a 3-point hedonic scale. The data show that children reduce their rating of a liked food once it has been in contact with a disliked food, in comparison to a like-like combination control measure. The data also show that girls show greater sensitivity than boys to this form of contamination and that the younger children are more likely to show a prolonged response (rating of the liked food does not return to the unadulterated level) than the older children in the sample. Several possible reasons for these findings are discussed including disgust, inferred distaste and associational contamination.

Attentional biases to foods: The effects of caloric content and cognitive restraint.
Forestell, CA, Lau, P, Gyurovski, II, Dickter, CL, Haque, SS
Appetite. 2012;(3):748-54
Abstract
The goal of the present study was to determine whether female restrained and unrestrained eaters demonstrated differential levels of attentional bias to high calorie foods when they were presented as distractors in a flanker task. This task consisted of four blocks of 68 trials in which three food pictures were briefly presented simultaneously on a computer screen. On each trial a high or low calorie target food was presented in the center of a pair of high or low calorie food flanker pictures and participants' reaction times to answer a basic question about whether they would consume the target food for breakfast were recorded. In Experiment 1, in which all participants were fed a snack prior to engaging in the flanker task, there was no evidence that restrained (n=29) or unrestrained (n=37) eaters had an attentional bias. However, in Experiment 2, when participants completed the flanker task while hungry, restrained eaters (n=27) experienced response conflict only when low calorie targets were flanked by high calorie distractors, whereas unrestrained eaters (n=46) were distracted by high calorie flankers regardless of the caloric content of the target cue. The results from this implicit task indicate that flankers interfere with hungry participants' responses to varying degrees depending on their cognitive restraint. Whether attentional bias to food cues subsequently affects food choices and eating behavior is a topic for further investigation.
