Pathways of the relationships among eating behavior, stress, and coping in adults with type 2 diabetes: A cross-sectional study

Eating behavior and dietary practices are associated with age, sex, body mass index, and body fat in individuals with type 2 diabetes and/or hypertension in Brazil

Type 2 diabetes (T2DM), hypertension, and obesity are major contributors to global mortality. This study aimed to evaluate eating behavior and dietary practices among individuals with T2DM and/or hypertension, examining their associations with sociodemographic and anthropometric characteristics. We hypothesized that these factors may contribute to body mass index (BMI) and body fat (BF) levels in these individuals. In a cross-sectional study, adults/older individuals diagnosed with T2DM and/or hypertension were included. Eating behavior was evaluated via Three-factor Eating Questionnaire-R21. Dietary practices were assessed using the Dietary Guidelines for the Brazilian Population (DGBP) questionnaire. Poisson regression examined associations between eating behaviors, dietary practices, and sociodemographic factors. Linear regressions were employed to analyze relationships between eating behavior, dietary practices, BMI, and BF. The study included 275 primarily female (70.5%) participants under 60 years old (54.2%). Male and older participants had a lower prevalence of high scores in the 'emotional eating' (EE; PR: 0.40 [0.25;0.63]) and 'uncontrolled eating' (UE; PR: 0.68 [0.50;0.92]) domains. In contrast, older patients had a higher prevalence of adherence to the DGBP recommendations (PR:1.53 [1.20;1.94]). A positive association was observed between high EE (β:3.71 [1.98;5.44]) and UE (β:2.85 [1.15;4.55]) scores and BMI, whereas higher dietary practice scores (β:-2.19 [-3.88;-0.50]) were negatively associated with BMI. High EE (β:2.20 [0.38;4.02]) and UE (β:1.92 [0.17;3.67]) scores were positively associated with BF regardless of the confounding factors included. Higher scores on the dietary practices were inversely associated with BF (β:-1.94 [-3.67;-0.21]). Understanding dietary behaviors and practices can facilitate a more comprehensive and effective treatment approach.

Inadequate care and excessive overprotection during childhood are associated with the presence of diabetes mellitus in adulthood in a general Japanese population: a cross-sectional analysis from the Hisayama Study

OBJECTIVE

To investigate associations between parenting styles during childhood and diabetes in adulthood in a Japanese community.

METHODS

In 2011, 710 community-dwelling Japanese residents aged ≥ 40 years were assessed for the presence of diabetes and for their perceptions of the parenting style of their parents, as measured using the "care" and "overprotection" scales of the Parental Bonding Instrument. Care and overprotection scores for each parent were dichotomized by age-specific median values. Diabetes mellitus was defined as a fasting plasma glucose level of ≥ 7.0 mmol/L, a 2-h post-loaded glucose level of ≥ 11.1 mmol/L, HbA1c ≥ 6.5%, and/or the current use of insulin or oral glucose-lowering agents. The odds ratios (ORs) for prevalent diabetes were calculated using a logistic regression model.

RESULTS

The prevalence of diabetes was 14.9%. Subjects with a high paternal overprotection score had a significantly greater likelihood of prevalent diabetes than those with a low paternal overprotection score after adjusting for confounders (OR 1.71, 95% confidence interval [CI] 1.06-2.77), while there was no significant association between paternal care and diabetes. Additionally, the multivariable-adjusted ORs for the presence of diabetes were significantly higher in subjects with a low maternal care score (OR 1.61, 95%CI 1.00-2.60) or in subjects with a high maternal overprotection score (OR 1.73, 95%CI 1.08-2.80). Moreover, the subjects with a low care score and high overprotection score for both their father and mother had a significantly higher multivariable-adjusted OR of diabetes than those with a high care score and low overprotection score for both parents (OR 2,12, 95%CI 1.14-3.95).

CONCLUSIONS

This study suggests that inadequate care and excessive overprotection during childhood may contribute to the development of diabetes in adulthood.

The Association between Personality Factors and Metabolic Parameters among Patients with Non-Alcoholic-Fatty Liver Disease and Type 2 Diabetes Mellitus-A Cross-Sectional Study

BACKGROUND

The increasing prevalence of type 2 diabetes mellitus (T2DM) and non-alcoholic fatty liver disease (NAFLD) states a serious problem for public health. The introduction of effective methods of treatment and prevention is crucial to avoid complications of these diseases. Among them, we can specify psychological factors that affect everyday life and determine the patient's attitude towards therapy, and what follows, their compliance in treatment. The literature indicates these connections in various ways; in our study, we extend this view to include a broader perspective of human personality.

OBJECTIVE

We decided to investigate the associations between personality factors and metabolic parameters in patients with NAFLD and T2DM in order to better understand the patient's approach to the treatment of a chronic disease, such as those mentioned, and to establish the basis for further research implementing psychological interventions in the treatment of NAFLD and T2DM.

METHODS

One hundred participants with NAFLD and T2DM underwent blood tests and anthropometric measures. Each of them was asked to complete five questionnaires evaluating their personality properties.

RESULTS

We revealed that a rise in body mass index is related to a fall in the emotional intelligence factor of utilizing emotions, and a rise in emotional perception. The decrease in task-oriented coping style and a rise in emotion-oriented coping style are associated with a waist-hip ratio increase. The increase in fasting plasma glucose is predicted by a decrease in task-oriented coping style score. A fall in social diversion coping style score is associated with a high-density lipoprotein increase; in turn, a triglycerides increase is connected with a decline in rhythmicity score.

CONCLUSIONS

The personality factors are in relationship in the management of NAFLD and T2DM. They affect a patient's approach to treatment, which is very important, because we know lifestyle and dietary interventions are an important part of the treatment of these diseases. The compliance manifests by lifestyle modifications, taking medications regularly, measuring blood glucose, and inspection visits in outpatients' clinics are a large part of a diabetic's life. Future studies introducing psychological intervention to improve, e.g., coping styles or rhythmicity are needed to implement new methods of patient management.

Perceived Risk of Diabetes Among Vietnamese Americans with Prediabetes: A Mixed Methods Study (Preprint)

BACKGROUND

Vietnamese Americans have a relatively high risk of developing diabetes at younger ages, yet there are no published studies exploring their risk perceptions.

OBJECTIVE

This mixed methods study describes perceived diabetes risk in the context of an underserved population.

METHODS

This study was guided by the Common-Sense Model of Self-Regulation. Snowball sampling was used to recruit 10 Vietnamese Americans with prediabetes and achieve data saturation. Qualitative and quantitative descriptive methodologies with data transformation were used to analyze data from semistructured interviews and questionnaires to explore the dimensions of perceived diabetes risk.

RESULTS

Participants were between the ages of 30 and 75 years with diversity also noted in diabetes risk factors. The 3 risk perception domains from qualitative data were risk factors, disease severity, and preventing diabetes. The main perceived diabetes risk factors were eating habits (including cultural influences), sedentary lifestyle, and family history of diabetes. Quantitative data supported qualitative findings of a low-to-moderate level of perceived diabetes risk. Despite the lower levels of perceived diabetes risk, Vietnamese Americans do believe that the severity of diabetes is a "big concern."

CONCLUSIONS

Vietnamese Americans with prediabetes have a low-to-moderate level of perceived diabetes risk. Understanding the perceived diabetes risk in this population provides a foundation for diabetes prevention interventions that consider cultural influences on diet and exercise.

Pri-miR-144 rs9279 is associated with type 2 diabetes and regulation of stress response

Single-nucleotide polymorphisms (SNPs) of microRNAs (miRNAs) may alter miRNA expression, binding affinity, and/or messenger RNA expression levels of the target genes, thus leading to disease susceptibility. This study explored the association between SNPs in neuroendocrine stress response-related miRNAs and type 2 diabetes (T2D). In the screening stage, the association between six candidate SNPs of miRNAs and T2D was analyzed in a case-control study including 504 T2D cases and 494 healthy controls. Homozygous GG genotype of pri-miR-144 rs9279 showed significant association with increased risk of T2D compared with homozygous TT genotype (adjusted odds ratio [OR] = 1.62, 95% confidence interval [CI]: 1.07-2.45; p = .023) and the combined TT/TG genotype (adjusted OR = 1.59, 95% CI: 1.08-2.36; p = .020). In the validation stage, the association was further validated in a second independent set of subjects. The GG genotype showed consistent directions and effect sizes that were identified in previous additive and recessive models. The expression levels of miRNAs were further compared between different genotypes in the 179 newly diagnosed cases and 183 frequency-matched healthy controls. As a result, the GG genotype carriers had significantly upregulated expression of plasma miR-144 and cortisol, as compared to individuals with TT and TG genotypes, respectively, in total subjects and subgroups (p < .05). Eventually, NR3C1 was proved to be a stress-related target gene of miR-144, indicating that pri-miR-144 rs9279 may contribute to the development of T2D by altering regulation of stress response.
