Independence of diabetes and obesity in adults with serious mental illness: Findings from a large urban public hospital.

OBJECTIVE: There is limited research on metabolic abnormalities in psychotropic-naïve patients with serious mental illness (SMI). Our study examined metabolic conditions in a large, ethnically diverse sample of psychotropic-naïve and non-naïve adults with SMI at an urban public hospital. METHODS: In this cross-sectional study of 923 subjects, the prevalences of hyperglycemia meeting criteria for type 2 diabetes mellitus (T2DM) based on fasting plasma glucose and obesity defined by BMI and abdominal girth were compared across duration of psychotropic medication exposure. Multiple logistic regression models used hyperglycemia and obesity as dependent variables and age, sex, race/ethnicity, and years on psychotropics as independent variables. RESULTS: Psychotropic-naïve patients, including both schizophrenia and non-psychotic subgroups, showed an elevated prevalence of hyperglycemia meeting criteria for T2DM and a decreased prevalence of obesity compared to the general population. Obesity rates significantly increased for those on psychotropic medications more than 5 years, particularly for patients without psychosis (BMI: aOR = 5.23 CI = 1.44-19.07; abdominal girth: aOR = 6.40 CI = 1.98-20.69). Women had a significantly higher obesity rate than men (BMI: aOR = 1.63 CI = 1.17-2.28; abdominal girth: aOR = 3.86 CI = 2.75-5.44). Asians had twice the prevalence of hyperglycemia as whites (aOR = 2.29 CI = 1.43-3.67), despite having significantly less obesity (BMI: aOR = .39 CI = .20-.76; abdominal girth: aOR = .34 CI = .20-.60). Hispanics had a higher rate of obesity by BMI than whites (aOR = 1.91 CI = 1.22-2.99). CONCLUSIONS: This study showed disparities between obesity and T2DM in psychotropic-naïve patients with SMI, suggesting separate risk pathways for these two metabolic conditions.

Identification of Diabetes Risk in Dental Settings: Implications for Physical and Mental Health.

The risk for diabetes risk is significantly elevated in persons who are older, overweight and have serious mental illness. However, primary care practitioners (PCP) tend to underestimate this risk. Although there are few opportunities for early detection of diabetes, blood exuded during routine oral exams in dental settings can be used to assess glycated hemoglobin (HbA1c) levels. The current study sought to understand how primary care practitioners would react to patients who screened positive for elevated HbA1c, how they estimated risk, and whether they provided treatment recommendations or counseling. Method: Semi-structured telephone interviews were conducted on 61 subjects three months after demonstrating elevated HbA1c levels from dental screenings. Data were transcribed and analyzed using content analysis. Results: Qualitative analyses revealed four themes according to patients: (1) "Being told I needed to make lifestyle changes" (41%); (2) Realizing I needed a new health care provider or medication change" (10%); (3) "Being told of the need for monitoring but no counseling/treatment change" (16%); and (4) "Being told everything is fine and there is nothing to worry about" (31%). Conclusions: Only half of the 61 cases reporting elevated HbA1C levels at screening experienced their PCP's as responding with counseling or medication changes. Almost a third of cases perceived that their PCP's dismissed the results, making no recommendations, and the rest perceived no counseling or interventions being proposed. Based on subjects' perceptions of their PCP's responses to their elevated HbA1c values, the impact of this intervention is substantially reduced over expectations.

Predictors of Depression Among Adult Women With Diabetes in the United States: An Analysis Using National Health and Nutrition Examination Survey Data From 2007 to 2012.

PURPOSE: The purpose of the study was to identify the sex-specific characteristics that predict depression among adult women with diabetes. METHODS: Data from the 2007-2012 National Health and Nutrition Examination Survey in the United States were used to identify the predictors of depression in a large sample of women ages 20 years and older with diabetes (n = 946). RESULTS: When extrapolated to almost 9 million women in the United States ≥ 20 years of age with diabetes, 19.0% had depression. Female-specific significant predictors of depression included younger age (< 65 years old), less than high school graduation, self-rated fair or poor health, inactivity due to poor health, and pain that interferes with usual activities. Marital status and diabetes-related factors (years living with diabetes, use of insulin, parent or sibling with diabetes) were not significant predictors of depression in adult women with diabetes. CONCLUSION: When educating and counseling women with diabetes, diabetes educators should be aware that some of the predictors of depression in women with diabetes differ from those of populations that include both sexes. Depression screening, although important for all women with diabetes, should especially be performed among women with female-specific depression predictors.

Measurement of HbA1c in Gingival Crevicular Blood Using a High-Pressure Liquid Chromatography Procedure.

OBJECTIVE: To validate an ion exchange high-pressure liquid chromatography (HPLC) method for measuring glycated hemoglobin (HbA1c) in gingival crevicular blood (GCB) spotted on filter paper, for use in screening dental patients for diabetes. METHODS: We collected the GCB specimens for this study from the oral cavities of patients during dental visits, using rigorous strategies to obtain GCB that was as free of debris as possible. The analytical performance of the HPLC method was determined by measuring the precision, linearity, carryover, stability of HbA1c in GCB, and correlation of HbA1c results in GCB specimens with finger-stick blood (FSB) specimens spotted on filter paper. RESULTS: The coefficients of variation (CVs) for the inter- and intrarun precision of the method were less than 2.0%. Linearity ranged between 4.2% and 12.4%; carryover was less than 2.0%, and the stability of the specimen was 6 days at 4°C and as many as 14 days at -70°C. Linear regression analysis comparing the HbA1c results in GCB with FSB yielded a correlation coefficient of 0.993, a slope of 0.981, and an intercept of 0.13. The Bland-Altman plot showed no difference in the HbA1c results from the GCB and FSB specimens at normal, prediabetes, and diabetes HbA1c levels. CONCLUSION: We validated an HPLC method for measuring HbA1c in GCB; this method can be used to screen dental patients for diabetes.

Awareness of Prediabetes and Diabetes among Persons with Clinical Depression.

Background. Major depressive disorder (MDD) is highly comorbid with diabetes, a relationship underappreciated by clinicians. Purpose. Examine the proportion of nonpregnant individuals ≥20 years with MDD and elevated glucose and the demographic and clinical characteristics associated with unrecognized elevated glucose. Methods. 14,373 subjects who participated in the National Health and Nutrition Examination Survey (2007-2012) completed the PHQ-9 depression screen and had hemoglobin A1C (HbA1c) measured. PHQ-9 scores ≥10 and HbA1c scores ≥5.7% were defined as MDD and elevated HbA1c, respectively. Data were analyzed using complex survey sampling software. Results. 38.4% of the sample with MDD had elevated HbA1c readings. Compared with nondepressed subjects, they were significantly more likely to have elevated glucose readings (P = 0.003) and to be aware of their elevated glucose levels if they had a higher body mass index, family history of diabetes, more doctor visits in the past year, a usual care source, health insurance, or were taking hypertension or hypercholesterolemia medications. Conclusions. Many adults with MDD have elevated HbA1c levels, have never been advised of elevated HbA1c, have not received diabetes screening, and have minimal contact with a healthcare provider. Additional opportunities for diabetes risk screening in people with MDD are needed.

The potential for glycemic control monitoring and screening for diabetes at dental visits using oral blood.

OBJECTIVES: We examined the potential for glycemic control monitoring and screening for diabetes in a dental setting among adults (n = 408) with or at risk for diabetes. METHODS: In 2013 and 2014, we performed hemoglobin A1c (HbA1c) tests on dried blood samples of gingival crevicular blood and compared these with paired "gold-standard" HbA1c tests with dried finger-stick blood samples in New York City dental clinic patients. We examined differences in sociodemographics and diabetes-related risk and health care characteristics for 3 groups of at-risk patients. RESULTS: About half of the study sample had elevated HbA1c values in the combined prediabetes and diabetes ranges, with approximately one fourth of those in the diabetes range. With a correlation of 0.991 between gingival crevicular and finger-stick blood HbA1c, measures of concurrence between the tests were extremely high for both elevated HbA1c and diabetes-range HbA1c levels. Persons already diagnosed with diabetes and undiagnosed persons aged 45 years or older could especially benefit from HbA1c testing at dental visits. CONCLUSIONS: Gingival crevicular blood collected at the dental visit can be used to screen for diabetes and monitor glycemic control for many at-risk patients.

Illness perceptions among adults at risk for diabetes.

PURPOSE: The purpose of this study is to examine diabetes illness perceptions among a sample of at-risk adults according to specific characteristics that make them vulnerable to diabetes. METHODS: At-risk adults (N = 372) participated in a study investigating the potential to screen them for diabetes at a large urban dental college. Sociodemographic and individual-level diabetes risk-related characteristics, A1C measures, diabetes-related symptoms, diabetes knowledge, diabetes illness perceptions, and perceived causes of diabetes were collected and reported for the study sample; t tests were then used to determine whether there were statistically significant differences in each of 8 dimensions of diabetes illness perceptions according to the presence or absence of 6 diabetes risk factors. RESULTS: Average A1C values were 5.6% (38 mmol/mol), and 46% of the study sample had A1C values in the prediabetes or diabetes range. Participants had various diabetes knowledge gaps and misperceptions, and there were differences in dimensions of diabetes illness perceptions depending on specific diabetes-related risk factors. CONCLUSIONS: In view of differences in the diabetes-related illness perceptions of persons at risk for diabetes, it is important for diabetes educators and other health care providers to personalize their diabetes-related education, management, and support to the specific needs and vulnerabilities of at-risk patients.

Low vitamin D levels predict clinical features of schizophrenia.

Vitamin D plays crucial roles in neuroprotection and neurodevelopment, and low levels are commonly associated with schizophrenia. We considered if the association was spurious or causal by examining the association of Vitamin D with Leukocyte Telomere Length (LTL), a marker of cellular aging. Vitamin D levels in 22 well-characterized schizophrenia cases were examined with respect to symptoms, cognition, and functioning. LTL was assessed using quantitative polymerase chain reaction (qPCR). The results showed that 91% (20) had deficient or insufficient Vitamin D levels, which were associated with excitement and grandiosity, social anhedonia, and poverty of speech. Sex-specific analyses showed strong associations of hypovitamintosis D to negative symptoms and decreased premorbid adjustment in males, and to lesser hallucinations and emotional withdrawal, but increased anti-social aggression in females. In females LTL was furthermore associated with Vitamin D levels. This study demonstrates a relationship of low vitamin D levels with increased cellular aging in females. It is also the first study to demonstrate potential sex-specific profiles among schizophrenia cases with hypovitaminosis.

Latinas with elevated fasting plasma glucose: an analysis using NHANES 2009-2010 data.

For Latinas with fasting plasma glucose (FPG) levels in the prediabetes and diabetes ranges, early detection can support steps to optimize their health. Data collected in 2009-2010 indicate that 36.7% of Latinas in the United States had elevated FPG levels. Latinas with elevated FPG who were unaware of their diabetes status were significantly less likely than non-Hispanic White and non-Hispanic Black women to have seen a health care provider in the past year (75.8%, 92.9%, and 90.2%, respectively; p = .018). With almost 1 million Latinas in the United States with elevated FPG unaware of their diabetes risk, and less likely than other at-risk women to see health care providers, there is an urgent need to establish alternate sites of opportunity for their diabetes screening.
