Healthcare Service Providers' Perspectives on Sociocultural Aspects Affecting Weight Management Activities Amongst People with Obesity in Taiwan-A Qualitative Study.

The prevalence of obesity and morbid obesity in Taiwan has risen sharply in recent decades, as in other parts of the world, necessitating urgent action to prevent and curb its detrimental effects. Asian populations are susceptible to the repercussions of obesity at a lower body weight. A higher BMI is associated with more frequent outpatient visits, in-hospital admissions, higher medical costs, and a lower quality of life. However, effective weight management approaches are unlikely to be maintained in the long term without assimilation into daily lifestyle practices. This qualitative study, based on semi-structured interviews with 14 doctors, dieticians, and nurses who work to control the weight of people with obesity, explored and identified multilevel barriers in the context of daily life to improve the efficacy and execution of weight management strategies. They considered diets, physical activity, and sleep as key weight management activities. The cultural and psychosocial aspects of daily life were observed to have an impact upon weight management, particularly family conflicts due to cultural dynamics and socially and culturally reinforced food practices. To improve population weight, less-recognised aspects need to be addressed alongside the inclusion of mental health specialists in weight management protocols and policy interventions to minimise obesogenic practices and create environments conducive to weight management.

Dietary intake and nutritional status of patients with phenylketonuria in Taiwan.

Phenylalanine hydroxylase (PAH) deficiency leads to phenylalanine accumulation and results in phenylketonuria (PKU). Phenylketonuria can contribute to severe inability such as mental impairment. Early diagnosis and dietary intervention can have beneficial effects on maintaining normal neural and cognitive function in patients with PKU. However, a long-term low phenylalanine diet may put children at risk of malnutrition. A food supplement was therefore used for children with PKU under dietician supervision according to dietary reference intakes (DRIs). In this cross-sectional study, we enrolled patients with PKU and age-matched controls to compare their anthropometry data [weight, height, body mass index (BMI), and body composition using bioelectrical impedance analysis (BIA)], and correlated it with their dietary intake based on 24-h dietary recall. For continuous parameters, the data were expressed as median ± standard deviation (SD), and the Mann-Whitney U test was used to test the difference among the groups. Correlation by natural proteins, body fat, and fat-free mass were evaluated using the Pearson correlation coefficient. Twenty-two participants diagnosed with PKU (ages 8-27 years; mean 15.23 ± 5.23) and a control group of 22 non-PKU participants (ages 8-39 years; mean 19.73 ± 10.6) were recruited for this study. Between the two groups of participants, no significant difference was found in height, weight, BMI, muscle mass, or fat mass. The percentage of natural protein has no effect on body composition. We found a significant positive correlation between the total protein intake percentage of DRIs and muscle mass (r = 0.491, p = 0.020) and a significant negative correlation in the total protein intake percentage of DRIs and fat mass (r = -0.475, p = 0.025) in participants with PKU. There were no significant differences in body composition and nutrition intake between patients with PKU (under metabolic control) and healthy subjects. Thus, giving proper nutrition treatment may have beneficial effects on body growth and nutrition status in patients with PKU in Taiwan.

Effects of Protein Supplementation Combined with Exercise Training on Muscle Mass and Function in Older Adults with Lower-Extremity Osteoarthritis: A Systematic Review and Meta-Analysis of Randomized Trials.

Aging and osteoarthritis (OA) are associated with a high risk of muscle mass loss, which can lead to physical disability. This study investigated the effectiveness of protein supplementation combined with exercise training (PS + ET) in improving muscle mass and functional outcomes in older adults with lower-limb OA. A comprehensive search of online databases was performed to identify randomized controlled trials (RCTs) on the effectiveness of PS + ET in older adults with hip or knee OA. Meta-analysis and risk of bias assessment of the included RCTs were conducted. Six RCTs were included in this systemic review; they had a median (range/total) Physiotherapy Evidence Database (PEDro) score of 7 (6-9) out of 10, respectively. Five RCTs that enrolled patients who underwent total joint replacement were included in this meta-analysis. The PS + ET group exhibited significant improvements in muscle mass (standard mean difference [SMD] = 1.13, p < 0.00001), pain (SMD = 1.36, p < 0.00001), and muscle strength (SMD = 0.44, p = 0.04). Our findings suggest that PS + ET improves muscle mass, muscle strength, and functional outcomes and reduces pain in older adults with lower-limb OA, particularly in those who have undergone total joint replacement.

Perceptions of Reducing Tube Feeding for Persons with Advanced Dementia among Various Professions in a Teaching Hospital.

BACKGROUND: Even though no evidence suggests tube feeding is beneficial for individuals with advanced dementia, many are still tube fed. OBJECTIVE: To assess perceptions of hospital staff regarding reducing tube feeding (RTF) of patients with advanced dementia. DESIGN: Cross-sectional survey. SETTING: A regional teaching hospital in Taipei, Taiwan. SUBJECTS: Hospital staff (n = 624), including physicians, nurses, dieticians, paramedical personnel, social workers, volunteers, attendants, and administrators. MEASUREMENTS: Anonymous questionnaires. RESULTS: The overall awareness of RTF for advanced dementia patients averaged 10.2 ± 3.74 points (maximum, 19 points) among all respondents. Among the different hospital professions, dieticians scored the highest, whereas nurses and attendants/volunteers had relatively low scores. Over half of respondents (57%) agreed tube feeding is the best choice for advanced dementia with dysphagia. Physicians of different specialties had significantly different responses toward RTF with regard to the belief that tube feeding reduces the risk of aspiration pneumonia, referring patients who refuse tube feeding to other health care team members, and the belief that family members would be able to accept the patient's death along with insufficient food/fluid intake. Only 35.1% of respondents believed they were able to implement comfort feeding. CONCLUSIONS: The present survey shows a persistent knowledge gap among various health care professions regarding tube feeding of patients with advanced dementia. Also, there is insufficient awareness about this subject, indicating that promotion of comfort feeding by enhanced training and communication within medical teams is essential to achieving better person-centered care and preventing unnecessary suffering.

A Taiwanese food frequency questionnaire correlates with plasma docosahexaenoic acid but not with plasma eicosapentaenoic acid levels: questionnaires and plasma biomarkers.

BACKGROUND: Little evidence is available for the validity of dietary fish and polyunsaturated fatty acid intake derived from interviewer-administered questionnaires and plasma docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) concentration. METHODS: We estimated the correlation of DHA and EPA intake from both questionnaires and biochemical measurements. Ethnic Chinese adults with a mean (± SD) age of 59.8 (±12.8) years (n = 297) (47% women) who completed a 38-item semi-quantitative food-frequency questionnaire and provided a plasma sample were enrolled. Plasma fatty acids were analyzed by capillary gas chromatography. RESULTS: The Spearmen rank correlation coefficients between the intake of various types of fish and marine n-3 fatty acids as well as plasma DHA were significant, ranging from 0.20 to 0.33 (P < 0.001). In addition, dietary EPA, C22:5 n-3 and DHA were significantly correlated with the levels of marine n-3 fatty acids and DHA, with the Spearman rank correlation coefficients ranging from 0.26 to 0.35 (P < 0.001). Moreover, compared with those in the lowest fish intake quintile, participants in the highest quintile had a significantly higher DHA level (adjusted mean difference, 0.99 ± 0.10%, test for trend, P < 0.001). Similar patterns between dietary DHA intake and plasma DHA levels were found. However, the association between dietary fish intake and plasma EPA was not significant (test for trend, P = 0.69). CONCLUSIONS: The dietary intakes of fish and of long chain n-3 fatty acids, as determined by the food frequency questionnaire, were correlated with the percentages of these fatty acids in plasma, and in particular with plasma DHA. Plasma DHA levels were correlated to dietary intake of long-chain n-3 fatty acids.

Sesamol induces nitric oxide release from human umbilical vein endothelial cells.

Sesamol, which is derived from sesame seed lignans, is reportedly an antioxidant. Nitric oxide (NO), the most important vascular relaxing factor, is regulated in the endothelium. In addition, NO is involved in protecting endothelium and has antiatherosclerotic and antithrombotic activities. The endothelium produces NO through the regulation of both endothelial NO synthase (eNOS) expression and activity in endothelial cells. This study sought to investigate the effect of sesamol on NO released from human umbilical vein endothelial cells (HUVEC) and to examine the expression and activity of eNOS. Sesamol induced NO release from endothelial cells in a dose-dependent manner (from 1 to 10 microM), as measured 24 h after treatment; the expression of the eNOS gene at both transcription and translation levels; and NOS activity in endothelial cells. The content of cGMP was also increased by sesamol through NO signaling. The transcription of eNOS induced by sesamol was confirmed through the activation of PI-3 kinase-Akt (protein kinase B) signaling. The results demonstrate that sesamol induces NOS signaling pathways in HUVEC and suggest a role for sesamol in cardiovascular reactivity in vivo.

Effects of a high-fiber diet on hepatocyte apoptosis and liver regeneration after partial hepatectomy in rats with fatty liver.

BACKGROUND: The morbidity and mortality that accompany fatty liver may occur as a result of increased apoptosis of hepatocytes and decreased liver regeneration. We determined the effects of a high-fiber diet on hepatocyte apoptosis and liver regeneration after partial hepatectomy in rats with fatty liver. METHODS: Fatty liver was induced in male Wistar rats weighing around 200 g through feeding of a high-fat diet for 4 weeks. The rats were then randomly assigned to 3 groups that received a high-fat diet, a normal diet, or a high-fiber diet for another 4 weeks. Partial hepatectomy (around 70%) was performed, and rats were killed 6, 24, 48, or 72 hours after hepatectomy. We then measured (1) the ratio of remnant liver weight to body weight and assessed the histology of the remnant liver as indicators of fatty liver, (2) caspase-3 activity and in situ cell death detection of DNA fragmentation as indicators of apoptosis, and (3) 5-bromo-2-deoxyuridine (BrdU) activity and (4) ornithine decarboxylase (ODC) contents in remnant livers as markers of regeneration. RESULTS: We found that (1) a high-fat diet for 4 weeks can markedly induce fatty liver, (2) apoptosis of hepatocytes is greater in fatty liver than in normal liver (98 +/- 19 vs 36 +/- 7) at 6 hours after partial hepatectomy (p < .05), (3) the capacity of liver regeneration decreases significantly (BrdU index: 30 +/- 5 vs 12 +/- 3, and ODC contents: 604 +/- 48 vs 390 +/- 42 mg/dL) in fatty liver 24 hours after partial hepatectomy (p < .05), (4) a normal diet can partially reverse the effects of fatty liver; (5) a high-fiber diet can significantly reverse the effects of fatty liver (p < .05). CONCLUSIONS: A high-fiber diet can reverse the negative effects of fatty liver on apoptosis and regenerative capacity after partial hepatectomy.

Sesamol regulates plasminogen activator gene expression in cultured endothelial cells: a potential effect on the fibrinolytic system.

Sesamol is a component in the nutritional makeup of sesame that was identified as an antioxidant. In recent years, the importance of the plasminogen activator (PA) and its adjustment factor, plasminogen activator inhibitor-1 (PAI-1), in the prevention of atherosclerosis has gradually received recognition. The objective of this in vitro study was to demonstrate the effects of sesamol on PA and PAI-1. We also compared the effects of sesamol with two well-known antioxidants, vitamins C and E, by using human umbilical vein endothelial cells as an experimental model and by treating them with the above-mentioned three nutrients with doses up to 100 micromol/L. After 24 h, cells and cultural medium were collected for analysis. The concentrations of tissue PA (tPA), urokinase PA (uPA) and PAI-1 were measured by an enzymatic immunity method. Northern blot method was used to analyze the expression of mRNA of these three types of proteins. The results showed that sesamol increased the production of uPA and tPA significantly and also up-regulated the mRNA expressions of these proteins. On the other hand, vitamins C and E could induce tPA but not uPA. As for PAI-1, none of the nutrients induced any evident response. These findings suggest that the overall vascular fibrinolytic capacity may be enhanced by using sesamol to regulate PA gene expression.

Sesamin induces nitric oxide and decreases endothelin-1 production in HUVECs: possible implications for its antihypertensive effect.

OBJECTIVE: Sesamin has been proved to be antihypertensive. Nitric oxide (NO) is the most important vascular relaxing factor that is regulated in endothelium. Endothelin-1 (ET-1) is characterized as a potent vasoconstrictor and is also regulated in endothelium. Alterations in the endothelial production of NO and ET-1 are known to correlate with hypertension. This study investigated the effect of sesamin on NO and ET-1 in the human umbilical vein endothelial cells (HUVECs). DESIGN: The concentrations of NO and ET-1 in the medium of HUVECs treated by sesamin were measured. The mRNA and protein expressions of nitric oxide synthase (NOS), endothelin converting enzyme-1 (ECE-1), and endothelin-1 (ET-1) were also investigated. Other than the mRNA and protein expression, NOS activity and cyclic GMP (cGMP) were detected. METHODS: The NO concentration was detected by colorimetric assay. The cGMP and ET-1 were analyzed by EIA. The eNOS, ECE-1, and ET-1 mRNA expressions were assayed by Northern blot. The eNOS and ECE-1 protein expressions were analyzed by Western blot. The NOS activity was assayed by detecting the level of [H]-1-citrullin transformed from [H]-1-arginine. RESULTS: Sesamin not only increased the NO concentration in the medium of HUVECs in a dose-dependent manner after 24 h, but also induced eNOS mRNA and protein expressions. NOS activity in the HUVECs was also induced by sesamin. The content of cGMP was induced by sesamin through NO signaling. On the other hand, the ET-1 concentration in the medium of HUVECs treated by sesamin was suppressed in a dose-dependent manner after 24 h. The ECE-1 protein and mRNA expressions were also inhibited by sesamin. However, the mRNA expression of prepro ET-1 was not influenced by sesamin. CONCLUSION: From the above results, it is suggested that sesamin may improve hypertension by its ability to induce NO and inhibit ET-1 production from endothelial cells. The increase of NO by sesamin is through the induction of eNOS gene expression. The decrease of ET-1 by sesamin is through the inhibition of ECE gene expression, but is not through the inhibition of prepro ET-1 gene expression.

Response of Taiwanese obese binge eaters to a hospital-based weight reduction program.

OBJECTIVE: To investigate the characteristics and prevalence of binge eating among overweight Taiwanese and to determine the effect of binge eating on outcome of weight loss treatment. METHODS: One hundred and eighty-nine participants in a 12-week traditional weight-reduction program were classified on the basis of the Bulimic Investigation Test, Edinburgh (BITE) scores into binge eaters (>/=20), subthreshold binge eaters (10-19), and nonbinge eaters (0-9). RESULTS: This study found a 15.9% prevalence of binge eating. The binge-eating groups (binge eaters and subthreshold binge eaters) were younger, had an earlier onset of obesity, and more psychological distress than nonbinge eaters. Differences in obesity treatment weight loss among binge eaters, subthreshold binge eaters, or nonbingers by last observation carried forward (LOCF) method were not significant. At the end of treatment, the subthreshold binge eaters had the greatest weight loss. Although their binge eating and mood significantly improved, binge eaters and subthreshold binge eaters still had significant pathology in eating behaviors at completion of the program. CONCLUSION: Alternative treatment strategies focusing on disordered eating behaviors are needed to supplement standard dietary management of overweight treatment-seeking binge eaters.

Psychobehavioral response and weight loss prediction in a hospital-based weight reduction program.

BACKGROUND AND PURPOSE: Depression and binge eating are common adverse psychologic responses associated with weight loss in overweight and obese adults. This study aimed to assess the effects of different degrees of weight loss on psychologic functioning and the relationship between mood change and weight reduction, and to identify predictors of short-term weight loss among subjects in a hospital-based weight reduction program. METHODS: A total of 189 obese subjects who participated in a hospital-based weight-reduction program during a 12-week interval were enrolled in this study. They ranged in age from 18 to 67 years (mean, 40.5 +/- 12.3 yr) with female predominance (87.8%). Mean body weight was 79.3 +/- 13.9 kg and mean body mass index was 31.1 +/- 3.8 kg/m2 on entry into the program. Body weight was periodically measured and subjects were asked to complete two self-administered questionnaires including the Brief Symptom Rating Scale (BSRS) and the Bulimic Investigatory Test, Edinburgh (BITE), pre- and post-treatment. RESULTS: Using the last observation carried forward method of analysis, the average weight loss for all participants was 5.6 +/- 3.7 kg. For subjects who completed the 12-week program, weight loss was 6.6 +/- 3.6 kg. Subjects who completed the program (n = 115, 60.8%) had significantly reduced BITE as well as all BSRS subscale scores at the end of the program. There was no linear relationship between mood change and weight loss by correlation analysis, but subjects with higher degrees of weight loss had improvement in more dimensions of psychologic functioning. Initial mood and binge-eating status predicted neither compliance nor weight reduction. Two biologic factors (initial weight loss, initial body weight) and one behavioral factor (attendance rate) were identified as significant predictors of short-term weight loss for all subjects. CONCLUSIONS: There was no evidence that weight loss made mood or eating pathology worse among those who completed the weight loss program. Beneficial effects on general psychologic functioning and eating pathology were demonstrated for subjects with a minimal weight loss of 5% of initial weight and who completed the program. Psychologic assessments at the start of the program did not predict weight loss at the end of participation in this hospital-based weight loss program.

The effectiveness of health promotion education programs for community elderly.

The purpose of this study was to examine the effectiveness of health promotion education programs for a group of elderly residents in a community. A one group pre- and post-test design was used in this study. Nurses, dietitians, and physical education teachers worked collaboratively to provide a series of comprehensive, integrated education programs. Course content included healthy life style and health promotion, disease prevention, nutrition, exercise, and medication education. A total of 140 elderly participated in this study. Ninety- seven subjects attended all of the education programs. A structured questionnaire was used for data collection. Information about demographics, health status, health promotion knowledge and behaviors was included. The health promotion behavior data were collected twice. The initial data set was collected prior to the first course and the second after the fifth course. Health promotion knowledge was assessed pre- and post-test in the second, third, and fourth courses. The research findings revealed that the education programs were effective in improving elderly health promotion knowledge and behaviors. The scores for health promotion knowledge and positive health behaviors were high among subjects who were aged 65-69 years, were married, lived with family members and had higher education levels. The results could be used as a reference in future health promotion education in the community.
