Dietary patterns and anthropometric indices among Iranian women with major depressive disorder

Major depression is a common mental disorder among women. A number of studies have demonstrated the association between some nutrients and food items with depression, but the studies on the association of dietary patterns with depression, especially in the Middle East, are rare. Further, the literature examining the relationship between anthropometric status and depression are inconsistent. In this study, 45 women with major depression and 90 patients with no mental disorder participated. We collected dietary intakes by a semi-quantitative food frequency questionnaire, and measured anthropometric indices (weight, height, waist and hip circumferences). Using factor analysis, two major dietary patterns were extracted: Healthy and Unhealthy. After adjusting for confounders, individuals who gained higher scores in healthy dietary pattern, had 84% lower odds of major depression; while the odds of major depression in participants who gained higher scores in unhealthy dietary pattern showed no significant association. No significant association was found between anthropometric indices and major depression. These results suggest that the healthy dietary pattern is significantly associated with lower odds of major depression in adult women. Further researches are needed to confirm these findings.     

Smoking and weight among patients using clozapine

Abstract

Background: Both obesity and smoking are common in schizophrenia patients taking clozapine, causing cardiovascular disease and premature deaths. Methods: Two hundred and thirty-seven patients with schizophrenia or related psychoses treated with clozapine completed the Liverpool University Neuroleptic Assessment Scale (LUNSERS) and a questionnaire including current height, weight, changes therein and smoking status. Aims: The aim of this study was to analyze weight and weight change in smoking and non-smoking patients taking clozapine. A possible interaction between obesity and smoking was explored. Results: No association was found between weight change and smoking status during clozapine treatment. There was no significant difference in body mass index (BMI) between non-smokers and smokers. In the analysis of covariance (ANCOVA) with BMI as the dependent variable, the best fitting model comprised age, sex, intensity of sedation, and reported amount of smoking as explanatory variables (ηp²= 0.116; P = 0.029; power = 0.750). None of the explanatory proportions of any single factor was significant. Conclusions: Estimated according to reported weight gain and BMI, no difference was found between smoking and non-smoking clozapine-treated patients. Number of cigarettes smoked explained BMI if age and sex were taken into account. This result is in line with the findings of some general population studies, where heavy smoking has been associated with a greater risk of obesity.     

Glycemic outcomes in patients with type 2 diabetes after bariatric surgery compared with routine care: a population-based,real-world cohort study in the United Kingdom

BackgroundClinical trials have shown that bariatric surgery (BS) is associated with better glycemic control and diabetes remission in patients with type 2 diabetes (T2D) compared with routine care.ObjectiveWe conducted a real-world population-based study examining the impact of BS on glycemic control and medications in patients with T2D.Setting and MethodsThis was a retrospective, matched, controlled cohort study conducted between January 1, 1990, and January 31, 2018, using IQVIA Medical Research Data, a primary care electronic records database. Adults with body mass index (BMI) ≥30 kg/m² and T2D who had BS (surgical) were matched for age, sex, BMI, and diabetes duration to two controls (with T2D and no BS).ResultsA total of 1126 patients in the surgical group and 2219 patients in the control group were analyzed. Mean (standard deviation) age was 50.0 (9.3) years, 67.6% were women, baseline glycocylated hemoglobin (HbA1C) was 7.8% (1.7 mmol/mol), and diabetes duration was 4.7 years (range, 2.0–8.4 years). Over a median (interquartile range) follow-up of 3.6 years (1.7–5.9 years), a higher proportion of patients in the surgical group achieved an HbA1C of ≤6.0% than the control group (65.8% versus 22.8%). The surgical group showed a decrease in mean HbA1C of 1.5% (95% confidence interval [CI]: 1.4%–1.7%), 1.4% (1.2%–1.5%), and 1.3% (1.1%–1.5%) at 1-, 2-, and 3-year follow-up, respectively, whereas HbA1C increased in the control group. The proportion of patients receiving glucose-lowering medications decreased in the surgical group (92.2% to 66.5%) but increased in the control group (85.3% to 90.2%).ConclusionBS is associated with significant improvement in glycemic control, achievement of normal HbA1C levels, and reduced need for glucose-lowering therapy in patients with T2D.     

Early-phase insulin hypersecretion associated with weight loss outcome after LSG: a prospective cohort study in Asian patients with BMI ≥28 kg/m2

BackgroundObesity has become a global problem that poses a serious threat to human health. Laparoscopic sleeve gastrectomy (LSG) is an effective long-term treatment. However, the weight loss of some patients after LSG is still insufficient. It is necessary to investigate the factors associated with inadequate weight loss after LSG.ObjectiveThe objective of this study was to explore whether preoperative insulin secretion could be associated with weight loss after LSG in patients with obesity.SettingThis is a single-center prospective cohort study conducted in a university hospital.MethodsPatients from a prospective database who underwent LSG were analyzed. All 178 participants underwent a 75-g oral glucose tolerance test (OGTT) to assess preoperative insulin and c-peptide secretion before LSG. The areas under the curve (AUCs) for glucose, insulin, and c-peptide were determined in the OGTT. The percentage of excess weight loss (%EWL) and the percentage of total weight loss (%TWL) were used to estimate the effect of weight loss after LSG. Regression models were used to assess the correlation between preoperative insulin and c-peptide secretion with %EWL ≥75% and TWL ≥35% at 12 months after LSG.ResultsThe AUCs of insulin and c-peptide were significantly lower in the %EWL ≥75% and %TWL ≥35% groups at 0–30 minutes, 0–60 minutes, and 0–120 minutes during the OGTT. At 30, 60, and 120 minutes during the OGTT, c-peptide levels were significantly lower in the %EWL ≥75% group and %TWL ≥35% group. The preoperative c-peptide level at 30 minutes during the OGTT (C₃₀) was significantly negatively correlated with %EWL (β = ?.37, P < .001) and %TWL (β = ?.28, P = .011). Univariate logistic regression analysis showed that preoperative C₃₀ was associated with %EWL ≥75% and %TWL ≥35% after LSG. According to multiple logistic regression analysis, patients with a low preoperative C₃₀ had an 8-fold higher %TWL ≥35% after LSG than those with a high C₃₀ (odds ratio: 8.41 [95% confidence interval: 1.46–48.58], P = .017). Similarly, patients with a low preoperative C₃₀ had a 7-fold higher EWL% ≥75% after LSG than patients with a high C₃₀ (odds ratio: 7.25 [95% confidence interval: 1.11–47.50], P = .039).ConclusionsThe rate of weight loss after LSG is low among patients with preoperative hyperinsulinemia. The preoperative c-peptide level at 30 minutes during the OGTT is associated with weight loss after LSG.     

Beliefs regarding the consequences of obesity and ideal weight: an instrument development study

OBJECTIVE: To address the current lack of psychometrically sound measures of beliefs regarding the consequences of obesity and ideal weight that has limited research to-date. METHODS: In phase one, interviews with 22 healthy-weight, overweight and obese individuals were conducted, subjected to theme analysis and used to develop 40 items. In phase two, unsound items were removed following item and principal components analyses of data from a community sample of 188 participants. In phase three, the items selected in phase two were administered to a second workforce population (n=302) to ensure their excellent psychometric properties were stable. In phase four, data were collected from 104 obese clinic attendees to establish the subscales' construct validity. RESULTS: The resultant Obesity Beliefs Scale (OBS) is comprised of three short, reliable, unidimensional and valid subscales written in language suitable for individuals aged 12 years and above. CONCLUSION: The OBS is a psychometrically sound measure of beliefs regarding the consequences obesity and ideal weight. PRACTICE IMPLICATIONS: The OBS has the potential to play a key role in prospective research designed to fully determine the role of beliefs in weight control behaviour. It can also be used to target and assess health education interventions.
