Effects of Dietary Carbohydrate Concentration and Glycemic Index on Blood Glucose Variability and Free Fatty Acids in Individuals with Type 1 Diabetes.

Monitoring glycemic control status is the cornerstone of diabetes management. This study aimed to reveal whether moderate-carbohydrate (CHO) diets increase the risk of free fatty acid (FFA) levels, and it presents the short-term effects of four different diet models on blood sugar, glycemic variability (GV), and FFA levels. This crossover study included 17 patients with type 1 diabetes mellitus to identify the effects of four diets with different CHO contents and glycemic index (GI) on GV and plasma FFA levels. Diet 1 (D1) contained 40% CHO with a low GI, diet 2 (D2) contained 40% CHO with a high GI, diet 3 (D3) contained 60% CHO with a low GI, and diet 4 (D4) contained 60% CHO with a high GI. Interventions were performed with sensor monitoring in four-day periods and completed in four weeks. No statistical difference was observed among the groups in terms of blood glucose area under the curve (p = 0.78), mean blood glucose levels (p = 0.28), GV (p = 0.59), and time in range (p = 0.567). FFA and total triglyceride levels were higher in the D1 group (p < 0.014 and p = 0.002, respectively). Different diets may increase the risk of cardiovascular diseases by affecting GI, FFA, and blood glucose levels.

A factor that can yield to eating attitude disorders in university students: Self-esteem.

OBJECTIVE: To determine prevalence of eating attitude disorder (EAD) and the effect of self-esteem on EAD in female university students.Study Design: In this cross-sectional study, female university students were included. The dependent variable was EAD determined by Eating Attitude Test-40. Socio-demographic characteristics, body perception, obesity, self-compassion and self-esteem were independent variables. Logistic regression (LR) models have been established to determine the associated factors of EAD. p < 0.05 was considered significant.Results: EAD were found in 3.3% (n = 20) of the participants (n = 600). 44.5% had low and medium self-esteem and %13.4 were overweight (body mass index (BMI) ≥ 25.0). According to LR models, after adjusted for age, increased self-esteem score (decreased self-esteem) (OR:1.8, 95%CI:1.063-3.303) and practicing popular diet (OR:12.6, 95%CI:4.439-35.904) increased the risk of EAD significantly.Conclusion: EAD were less than expected in this group of university students. Self-esteem is an important factor affecting EAD. Students with EAD may be recommended to get psychological support as well as nutritional counseling.

Turkish version of the 'Three-Factor Eating Questionnaire-51' for obese individuals: a validity and reliability study.

OBJECTIVES: Obesity is a serious public health issue. Investigating the eating behaviour of individuals plays an important role in preventing obesity. Therefore, the purpose of the current study is to adapt the long and first version of the 'Three-Factor Eating Questionnaire' (TFEQ), a scale that examines the eating behaviour of individuals, to Turkish culture and to carry out its validity and reliability study. DESIGN: The data were collected using data collection forms, and anthropometric measurements of the individuals were made by the researchers. The data collection form included several parameters: socio-demographic characteristics, the TFEQ scale, whose validity and reliability analysis is conducted here, and the Dutch Eating Behaviour Questionnaire (DEBQ) which was used as a parallel form. SETTING: The Obesity Clinic at Ege University in Izmir. PARTICIPANTS: The study group consisted of obese adult individuals (n 257). RESULTS: It was seen that constructing the questionnaire with twenty-seven items and four sub-dimensions provides better information about Turkish obese individuals. Factor loadings ranged from 0·421 to 0·846, and item total score correlations ranged from 0·214 to 0·558. Cronbach's α coefficient was found to be 0·639 for the whole scale. A positive, strong and statistically significant correlation was detected between TFEQ and DEBQ, which was used as a parallel form (r = 0·519, P < 0·001). CONCLUSION: In Turkey, the long version of the TFEQ scale was found valid and reliable for obese adult individuals. TFEQ can be used by clinicians or researchers to study the eating behaviour of obese individuals.

Assessment of the relationship between food addiction and nutritional status in schizophrenic patients.

OBJECTIVE: Obesity is one of today's most important public health problems. It is suggested that overeating and substance addiction show similarities, and addiction to food may be an important factor in the obesity epidemic. This study aimed to determine the prevalence of food addiction among schizophrenic patients and to examine the relationship between food addiction and anthropometric measurements and dietary nutrient intake. METHODS: Study participants included a total of 104 schizophrenic outpatients, 62 females and 42 males. Food addiction was assessed by using the Yale Food Addiction Scale, and the anthropometric measurements of participants and their three-day food consumption were recorded. RESULTS: This study found that more than half of the schizophrenic patients (60.6%) had food addiction, and that female schizophrenic patients had a higher prevalence (62.9%) of food addiction than male patients (57.1%). More than one-third of the schizophrenic patients with food addiction (41.3%) were found to be obese and their BMI, body weight, waist circumference, and body-fat ratio were higher than those of schizophrenic patients who did not have food addiction (P > 0.05). Moreover, the schizophrenic patients with food addiction were found to take significantly more energy, carbohydrate, and fat in their diet (P < 0.05). CONCLUSION: It was observed that the development of food addiction in schizophrenic patients increased the risk of obesity and cardiovascular diseases, which were found to be at higher levels in these patients. Educational programs should be planned for these patients to acquire health dietary habits and to increase their physical activity levels, and an additional psychosocial support should be provided for patients with food addiction.

Plasma Levels of Antioxidant Vitamins in Patients with Acromegaly: A Case-Control Study.

OBJECTIVE: The aim of this study was to compare antioxidant vitamin C and vitamin E levels in the non-acromegaly control group and in patients with acromegaly with and without remission. MATERIAL AND METHODS: In this study, 100 cases, acromegaly patients of 57% (n=57, 29F, 28M, mean ages of 49.5±12.1) and control subjects of 43% (n=43, 29F, 14M, mean ages of 49.6±9.2). Acromegaly patients were classified into two groups; active acromegaly (AA; n=33) and controlled acromegaly (CA; n=24). RESULTS: Vitamin C levels were significantly lower in the acromegaly group [7.6 (4.7) mg/L, as median (IQR)] when compared to the control group [12.2 (5.5) mg/L, as median (IQR)] (p <0.001). Vitamin E levels didn't show a significant difference between the acromegaly and the control groups (14.2±3.6 vs. 14.8±3.7, as mean±SD, respectively, p = 0.439). Correlation analysis showed that vitamin C levels were not significantly associated with clinical, anthropometric and laboratory parameters in the acromegaly group. Vitamin E levels were significantly associated with the total cholesterol, triglyceride, LDL-C, HDL-C, APO A1, APO B both in the acromegaly and the control groups. CONCLUSION: This study is the first one to investigate the relationship between the levels of vitamin C & E and anthropometric & metabolic parameters in acromegaly patients and control group. In our study, vitamin C level was significantly lower in the acromegaly group compared to the level in the control group. There was no significant difference in vitamin E levels between the acromegaly and control group.

Intuitive eating in youth: Its relationship with nutritional status / Alimentação intuitiva na juventude: sua relação com o estado nutricional

ABSTRACT Objective To determine intuitive eating in young adults and the effects of factors such as gender, Body Mass Index and dietary intake, and dietary adequacy on intuitive eating. Methods This cross-sectional study was conducted with students at Gazi University in Ankara (N=665; 17.6% men; 82.4% women). The questionnaire, including the general characteristics, anthropometric measurements, Intuitive Eating Scale-2, and 24-H Dietary Recall sections, were applied to all participants. For the evaluation of the diet, Nutrient Adequacy Ratio and Mean Adequacy Ratio were used. Results The mean Intuitive Eating Scale-2 score was 3.2±0.33; men's and women's scores were 3.3±0.37 and 3.2±0.32, respectively (p<0.05). According to linear regression analysis, gender, age and mean adequacy ratio had an effect on the model for the score (p<0.05). In addition, there was a negative correlation between Intuitive Eating Scale-2 scores and Body Mass Index values in women (rp=-0.095, p=0.026). Conclusion The intuitive eating scores varied according to gender, dietary adequacy and age. Intuitive eating may be effective in the formation of long-term behavioral changes, which is beneficial for the treatment of obesity. The result of this study may encourage the development of this behavior in groups (may vary according to gender), that is thought to be effective by considering the changes of intuitive eating behavior.

Métodos Este estudo transversal foi realizado em estudantes da Universidade de Gazi, em Ancara (N=665; 17,6% homens; 82,4% mulheres). O questionário, incluindo as características gerais, medidas antropométricas, Escala de Alimentação Intuitiva 2 e recordatório alimentar de 24 horas foi aplicado aos participantes. Para a avaliação da dieta, foram utilizados o Índice de Adequação de Nutrientes e a Razão de Adequação Média. Resultados A Escala Média de Escala de Comportamento Intuitivo-2 foi de 3,2±0,33, dos homens e das mulheres, foi de 3,3±0,37 e 3,2±0,32, respectivamente (p<0,05). De acordo com a análise de regressão linear, sexo, idade a Razão de Adequação Média tiveram efeito no modelo formado pelo escore (p<0,05). Além disso, houve uma correlação negativa entre os escores da Escala de Alimentação Intuitiva-2 e os valores do índice de massa corporal nas mulheres (rp=-0,095, p=0,026). Conclusão Os escores alimentares intuitivos variaram de acordo com o gênero, com adequação da dieta e com a idade. A alimentação intuitiva pode ser eficaz na formação de mudanças a longo prazo no comportamento, o que é benéfico para o tratamento da obesidade. O resultado deste estudo pode encorajar o desenvolvimento deste comportamento em grupos (talvez variar de acordo com o gênero) que é considerado efetivo considerando-se as mudanças do comportamento alimentar intuitivo.

Increase in subcutaneous adipose tissue and fat free mass in women with polycystic ovary syndrome is related to impaired insulin sensitivity.

OBJECTIVES: The present study was performed to search whether subcutaneous and whole body adipose tissue increase and they relate to measures of insulin sensitivity in women with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS: 52 women with PCOS and 53 healthy controls, all with similar age and body mass index participated in the study. A skinfold caliper device was used to measure biceps, triceps, subscapular and suprailiac skinfold thickness (SFT). Mid-upper arm circumference (MUAC) was measured using a tape measure. Body fat distributions were determined by bioelectrical impedance analysis. Insulin resistance score was computed with the HOMA formula. Plasma adiponectin was measured by EIA. RESULTS: SFT in all defined areas, MUAC, total body and trunk fat free mass, and HOMA score were higher in women with PCOS compared with healthy women, while adiponectin level was significantly lower. SFT values correlated positively with HOMA score, and negatively with blood adiponectin level. Regression analysis indicated, SFT in triceps and supscapular areas, trunk fat mass, trunk fat ratio, fat free mass and trunk fat free mass values as the most powerful predictors of HOMA score. CONCLUSIONS: The present study showed that SFT in different body regions and fat-free tissue mass are increased in women with PCOS, with a significant relation to impaired insulin sensitivity.

Assessment and evaluation of the nutritional status of the elderly using 2 different instruments.

OBJECTIVES: The elderly population continues to increase in most countries and inadequate nutrition is a common problem affecting their functional and physical status. Therefore, we should periodically assess the nutritional status of the elderly using practical methods. Our study objectives are to assess the nutritional status of the elderly using 2 different methods: Mini Nutritional Assessment (MNA) and Nutritional Screening Initiative Checklist (NSIC), and to evaluate the consistency of the methods. METHODS: We carried out a cross-sectional study between February 2003 and March 2004. We included a total of 1,564 elderly volunteers living in Ankara, Turkey, with median (+/- inter quartile range [IQR]) age of 70 +/- 8 (Male: 71 +/- 9; Female: 70 +/- 9 ) years. We utilized 2 frequently used instruments; MNA and NSIC in this study. RESULTS: The MNA results (<17 points) indicated that 6.5% of the male and 8.8% of the female participants had inadequate nutrition. According to NSIC, 34.3% of males and 36.9% of females were classified as having a high risk of nutritional deficiency. We observed a decrease in MNA and an increase in NSIC scores with the increase of age (p<0.01). We determined a negative correlation of MNA and positive correlation of NSIC with body weight, body mass index (BMI), mid-upper arm circumference (MUAC), and calf circumference (CC) (p<0.01). We did not find correlations between MNA and NSIC score to be statistically significant (r:-0.318; p>0.05). We analyzed agreements between MNA and NSIC score by Kappa statistical method (kappa: 0.13, p: 0.285) and determined that neither of these 2 methods can be used in lieu of the other. CONCLUSION: For the assessment of the nutritional status of the elderly, we could use both MNA and NSIC instruments but depending on the facilities and preferences, we cannot use one to replace the other. The MNA includes both anthropometric measurements and various nutritional parameters, and is a practical and most valid method.
