Relationship between erectile dysfunction and silent myocardial ischemia in type 2 diabetic patients with no known macrovascular complications.

INTRODUCTION: Erectile dysfunction (ED) is associated with cardiovascular disease (CVD) because it is highly prevalent among those with cardiovascular risk factors (CVRFs). Moreover, it precedes the development of CVD and is considered a subrogate marker of subclinical CVD. AIM: The aim of this study was to evaluate the presence of ED among patients with type 2 diabetes (DM2) without macroangiopathy, and to assess the association between ED and other CVRFs, chronic diabetes complications, silent myocardial ischemia (SMI), and peripheral arterial disease (PAD). METHODS: One hundred fifty-four male patients with DM2 and without clinical evidence of CVD were included in the study. The presence of ED, PAD, SMI, chronic diabetic complications, and other CVRFs was evaluated in these patients. MAIN OUTCOME MEASURES: PAD; SMI; ED; 24-hour blood pressure Holter; lipid profile; insulin resistance; testosterone; chronic inflammation; nephropathy; retinopathy; neuropathy. RESULTS: Prevalence of ED was 68.2%. Patients with ED were older and characterized by DM2, systolic blood pressure (BP), retinopathy, and insulin treatment of longer duration than patients without ED, even when adjusting for age was performed. Adjusting for duration of diabetic condition revealed significant differences in age and systolic BP. Independent factors for ED were age (57.7±7.5 years, relative risks [RR 1.1], P=0.003) and duration of diabetes (9[3-15] years, RR 1.1, P=0.006). SMI was detected in 13.6% of patients (18.1% in patients with ED vs. 4.1% in patients without ED). Asymptomatic PAD was detected in 13.2% of subjects (14.4% in patients with ED vs. 10.4% in patients without). CONCLUSIONS: ED is highly prevalent in DM2, and is associated with the presence of SMI, higher systolic BP and chronic microvascular diabetic complications.

Self-injurious and suicidal behaviour in a transsexual adolescent and young adult population, treated at a specialised gender identity unit in Spain. / Antecedentes de comportamientos autolesivos y autolíticos en población adolescente y adulta joven transexual, atendida en una unidad especializada en identidad de género en España.

INTRODUCTION: Nonsuicidal self-injury (NSSI) and suicidal behavior (SB) have a significant prevalence in transsexual people. The published data is confusing as it does not distinguish between ideation and realization, age groups, gender, or the degree of medical intervention. Their actual prevalence in Spain is unknown. OBJECTIVE: Our objective was to investigate the prevalence of NSSI behavior and SB in adolescents and young transsexual adults, differentiating between ideation and consummated behavior, prior to their receiving any type of gender-affirming medical treatment. MATERIAL AND METHODS: We retrospectively reviewed the medical history of a cohort of transsexual people aged between 10 and 35 years, treated at the Gender Identity Unit of the Valencian Community. We analyzed the data collected regarding the presence of four variables: NSSI ideation, NSSI behavior, ideas of suicide and suicide attempts, as well as differences according to age group and gender. RESULTS: The final sample consisted of 110 transsexual men and 90 transsexual women. Of these, 21% had made a suicide attempt, 50% had had suicidal ideas, 31% had a history of NSSI behavior and 35% had had NSSI ideas. No differences were found based on gender. Regarding age, subjects under 20 years of age presented a significantly higher prevalence regarding suicidal ideas compared to young adults (43% vs. 25%), while in the remaining variables, no statistically significant differences were found. CONCLUSIONS: The prevalence of a history of suicidal ideas and behavior in the Spanish adolescent and young transsexual population is significant and does not differ according to gender or age range. The prevalence of NSSI ideas and behavior differs and is more frequent in adolescent transsexuals.

Insulin Withdrawal in Diabetic Kidney Disease: What Are We Waiting for?

The prevalence of type 2 diabetes mellitus worldwide stands at nearly 9.3% and it is estimated that 20-40% of these patients will develop diabetic kidney disease (DKD). DKD is the leading cause of chronic kidney disease (CKD), and these patients often present high morbidity and mortality rates, particularly in those patients with poorly controlled risk factors. Furthermore, many are overweight or obese, due primarily to insulin compensation resulting from insulin resistance. In the last decade, treatment with sodium-glucose cotransporter 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1-RA) have been shown to be beneficial in renal and cardiovascular targets; however, in patients with CKD, the previous guidelines recommended the use of drugs such as repaglinide or dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors), plus insulin therapy. However, new guidelines have paved the way for new treatments, such as SGLT2i or GLP1-RA in patients with CKD. Currently, the new evidence supports the use of GLP1-RA in patients with an estimated glomerular filtration rate (eGFR) of up to 15 mL/min/1.73 m2 and an SGLT2i should be started with an eGFR > 60 mL/min/1.73 m2. Regarding those patients in advanced stages of CKD, the usual approach is to switch to insulin. Thus, the add-on of GLP1-RA and/or SGLT2i to insulin therapy can reduce the dose of insulin, or even allow for its withdrawal, as well as achieve a good glycaemic control with no weight gain and reduced risk of hypoglycaemia, with the added advantage of cardiorenal benefits.

Testosterone levels in males with type 2 diabetes and their relationship with cardiovascular risk factors and cardiovascular disease.

INTRODUCTION: One of the factors involved in type 2 diabetes in males is a reduction in levels of testosterone, which has been shown to predict resistance to insulin and the development of cardiovascular diseases. AIM: To assess the levels of testosterone in patients with type 2 diabetes and to evaluate their relationship with cardiovascular risk factors, peripheral arterial disease (PAD) and silent myocardial ischemia (SMI). METHODS: Total testosterone and sex hormone binding globulin were measured and free and bioavailable testosterones were calculated using Vermeulen's formula. Levels of total testosterone > or = 12 nmol/L or free testosterone > 225 pmol/L were considered normal. PAD was evaluated using the ankle-brachial index. SMI was assessed using a baseline ECG, Doppler echocardiogram, 24-hour electrocardiogram (ECG) Holter, exercise stress testing (EST), nuclear stress (if EST inconclusive), and if the result was positive, a coronary angiography. MAIN OUTCOME MEASURES: PAD, SMI, testosterone, erectile dysfunction, 24-hour blood pressure Holter, body mass index (BMI), waist circumference, lipid profile, insulin resistance, chronic inflammation, United Kingdom Prospective Diabetes Study cardiovascular risk score, nephropathy, retinopathy, and neuropathy. RESULTS: The study population was composed of 192 diabetic males with a mean age of 56.1 +/- 7.8 years and without a history of vascular disease. Twenty-three percent presented total testosterone below normal and 21.8% presented low free testosterone. BMI, waist circumference, neuropathy, triglycerides, C-reactive protein (CRP), glucose, insulin, and HOMA-IR were found to be significantly incremented with respect to subjects with normal testosterone. There was a negative correlation of HOMA-IR with total testosterone. PAD was detected in 12% and SMI in 10.9% of subjects, and differences were not related to testosterone levels. CONCLUSIONS: We have verified the prevalence of low testosterone levels in male patients with type 2 diabetes and have related them to variations in BMI, waist circumference, neuropathy, triglycerides, CRP, glucose, insulin and HOMA-IR, but not with an increase of SMI or PAD.

Spanish population trends in Internet searches for information on different diets. / Tendencia de la población española de búsqueda en internet sobre información relacionada con diferentes dietas.

OBJECTIVE: To use Google Trends to explore the trends of interest of the Spanish population regarding information related to different types of diets, focused on those that are popular and with evidence-based studies, over the last 10years. MATERIAL AND METHODS: The search trends referred to the terms «Mediterranean diet¼, «ketogenic diet¼, «low fat diet¼, «intermittent fasting¼ and «vegan diet¼ were analyzed. The relative search volumes (RSV) of the terms were compared. The direction of the trend was studied using the Spearman's correlation coefficient (SC). RESULTS: «Mediterranean diet¼ was the most widely searched term, with a median RSV of 16 (interquartile range [IQR] 6; range 8-100), though it exhibited a decreasing chronological trend (SC=-0.216). It was followed by «ketogenic diet¼, with an RSV of 8 (IQR 9; range 1-57); «vegan diet¼, with an RSV of 4 (IQR 5; range 0-16); «intermittent fasting¼, with an RSV of 2 (IQR 5; range 0-27), and «low fat diet¼, with an RSV of 1.16 (IQR 0; range 0-2). The term with the best correlation over time was «intermittent fasting¼ (SC=0.96), followed by «ketogenic diet¼ (SC=0.91) and «vegan diet¼ (SC=0.85). CONCLUSIONS: In Spain, the interest of the population in information about the Mediterranean diet is greater than for other diets. However, in recent years there has been a progressive increase in interest (measured as RSV) in other diets such as the ketogenic diet, vegan diet or intermittent fasting, and there has been a decrease in interest in the Mediterranean diet. The low fat diet does not generate interest in the Spanish population.

Transsexuality: Transitions, detransitions, and regrets in Spain. / Transexualidad: transiciones, detransiciones y arrepentimientos en España.

INTRODUCTION: Health care demand by transsexual people has recently increased, mostly at the expense of young and adolescents. The number of people who report a loss of or change in the former identity feeling (identity desistance) has also increased. While these are still a minority, we face more and more cases of transsexual people who ask for detransition and reversal of the changes achieved due to regret. OBJECTIVE: To report our experience with a group of transsexual people in detransition phase, and to analyze their personal experience and their associated conflicts. MATERIAL AND METHODS: A cohort of 796 people with gender incongruence attending the Identity Gender Unit of Doctor Peset University Hospital from January 2008 to December 2018 was studied. Four of the eight documented cases of detransition and/or regret are reported as the most representative. RESULTS: Causes of detransition included identity desistance, non-binary gender variants, associated psicomorbidities, and confusion between sexual identity and sexual orientation. CONCLUSION: Detransition is a growing phenomenon that implies clinical, psychological, and social issues. Inadequate evaluation and use of medicalization as the only means to improve gender dysphoria may lead to later detransition in some teenagers. Comprehensive care by a multidisciplinary and experienced team is essential. As there are no studies reporting the factors predictive of detransition, caution is recommended in cases of atypical identity courses.

Type 1 diabetes mellitus and periodontal disease: relationship to different clinical variables.

OBJECTIVE: This study is designed to evaluate the frequency of periodontal disease in a group of patients with type 1 diabetes mellitus and how this relates with diabetes metabolic control, duration of diabetes, and presence of diabetic complications. METHODS: A comparison was made of periodontal parameters (plaque index, bleeding index, pocket depth and attachment loss) in a group of diabetic patients (n=90) versus a group of non-diabetics (n=90). Logistic regression analysis was performed to evaluate relationship between periodontal parameters and degree of metabolic control, the duration of the disease, and the appearance of complications. RESULTS: Diabetics had greater bleeding index (p< 0.01), deeper periodontal pockets (p< 0.01) and more periodontal attachment loss (p< 0.01) than non-diabetics. Deficient metabolic control and presence of diabetic complication were associated with higher bleeding index and pocket depth (p

[Cardiovascular risk factors in patients with morbid obesity: weight loss influence]. / Factores de riesgo cardiovascular en pacientes con obesidad mórbida: influencia de la pérdida de peso.

BACKGROUND: We studied the presence of cardiovascular risk factors in patients with morbid obesity and analyzed the influence of weight loss achieved through diet on these factors. We also evaluated the influence of gender on the presence of cardiovascular risk factors and on its response to diet. PATIENTS AND METHODS: An anthropometric evaluation was performed in patients with morbid obesity (23 men and 36 women). The presence of cardiovascular risk factors was evaluated (fibrinogen, blood pressure, glucose metabolism determination by means of oral glucose tolerance test, complete lipid profile, sleep apnea syndrome), before and after following, on an alternative fashion, very-low calorie and low-calorie diets. The comparison was made with the t-test for paired samples. RESULTS: A very significant weight loss was achieved in our patients, particularly in men (decrease of 33.4 kg, 95% CI: 26.9 to 39.8). This was accompanied by a reduction in the presence of cardiovascular risk factors, particularly in men, in whom the body fat distribution improved significantly (decrease in waist: 24.8 cm, 95% CI 18.4 to 36.5), as well as the lipid profile including triglycerides, VLDLc, HDLc and B100 apoprotein. CONCLUSIONS: Patients with morbid obesity have a high prevalence of cardiovascular risk factors. A significant reduction of this prevalence can be achieved with diet during one year. This improvement is particularly significant in men.

[Prevalence of metabolic syndrome in patients with coronary heart disease]. / Prevalencia del síndrome metabólico entre pacientes con cardiopatía isquémica.

BACKGROUND AND OBJECTIVE: We aimed to know the prevalence of classical cardiovascular risk factors, hyperinsulinism, insulin resistance and metabolic syndrome (MS) in a population with coronary heart disease (CHD) as compared with a population without personal or familial history of cardiovascular risk factors. SUBJECTS AND METHOD: This was an observational and transversal study of cardiovascular risk factors making up the MS in an adult population. 367 subjects aged 35-79 years (268 men and 99 women) were studied; 185 had CHD (141 men and 44 women) and 182 (127 men and 55 women) were included as a control population. 82 individuals of the control group who had no MS components were selected for the calculation of parameters of hyperinsulinism and the HOMA (Homeostasis Model Assessment) index in order to evaluate the insulin resistance. RESULTS: As compared with the control group, patients with CHD showed higher blood pressure (systolic and dyastolic), body mass index (BMI), triglicerydes and apo B100 concentrations, and lower HDL-c and apo A1 values. They also exhibited higher values of glycemia and insulinemia and consequently a higher HOMA index. The values of insulin and HOMA (percentil 75), obtained from the selected group for this purpose, were 12 U/ml and 3.03, respectively. In the CHD population, 38.28% (95% CI, 31.13-45.95) had hyperinsulinism, 47.02% (95% CI, 39.70-54.47) had insulin resistance (HOMA) and 41.08% (95% CI, 33.98-48.55) had MS. CONCLUSIONS: There was a high prevalence of cardiovascular risk factors in the CHD population. Patients with CHD have higher hyperinsulinism and insulin resistance as well as a greater prevalence of MS. Despite treatment, a clear association exists between MS and CHD in both men and women.

Human leukocyte/endothelial cell interactions and mitochondrial dysfunction in type 2 diabetic patients and their association with silent myocardial ischemia.

OBJECTIVE: Diabetes is associated with oxidative stress and increased mortality, but a possible correlation between leukocyte-endothelium interactions, oxidative stress, and silent myocardial ischemia (SMI) is yet to be confirmed. RESEARCH DESIGN AND METHODS: Mitochondrial dysfunction and interactions between leukocytes and human umbilical vein endothelial cells were evaluated in 200 type 2 diabetic patients (25 with SMI) and 60 body composition- and age-matched control subjects. A possible correlation between these parameters and the onset of SMI was explored, and anthropometric and metabolic parameters were also analyzed. RESULTS: Waist, levels of triglycerides, proinflammatory cytokines (interleukin-6 and tumor necrosis factor-α), HbA1c, high-sensitivity C-reactive protein (hs-CRP), glucose, and insulin, and homeostasis model assessment of insulin resistance were higher in diabetic patients than in control subjects. However, no statistical differences in hs-CRP and insulin levels were detected when the data were adjusted for waist. None of these parameters varied between SMI and non-SMI patients. Mitochondrial function was impaired and leukocyte-endothelium interactions were more frequent among diabetic patients, which was evident in the lower mitochondrial O2 consumption, membrane potential, polymorphonuclear cell rolling velocity, and GSH/GSSG ratio, and in the higher mitochondrial reactive oxygen species production and rolling flux, adhesion, and vascular cell adhesion molecule-1 (VCAM-1) and E-selectin molecules observed in these subjects. Moreover, these differences correlated with SMI. Statistical differences were maintained after adjusting the data for BMI and waist, with the exception of VCAM-1 levels when adjusted for waist. CONCLUSIONS: Oxidative stress, mitochondrial dysfunction, and endothelium-inducing leukocyte-endothelium interactions are features of type 2 diabetes and correlate with SMI.

Tendencia de la población española de búsqueda en internet sobre información relacionada con diferentes dietas / Spanish population trends in Internet searches for information on different diets

OBJETIVO: Explorar a través Google Trends las tendencias del interés de la población española sobre información relacionada con diferentes tipos de dietas, focalizadas en las más populares y con estudios de evidencia, a lo largo de los últimos 10 años. MATERIAL Y MÉTODO: Se analizaron las tendencias de búsqueda de los términos «dieta mediterránea», «dieta cetogénica», «dieta baja en grasas», «ayuno intermitente» y «dieta vegana». El volumen relativo de búsqueda (VRB) de cada término fue comparado. La dirección de la tendencia se estudió mediante la correlación de Spearman (CS). RESULTADOS: El término «dieta mediterránea» fue el más buscado, con una mediana de VRB de 16 (rango intercuartil [RI] 6; rango 8-100), aunque siguió una tendencia cronológica decreciente (CS = -0,216). Le siguieron «dieta cetogénica», con VRB de 8 (RI 9; rango 1-57); «dieta vegana», con VRB de 4 (RI 5; rango 0-16); «ayuno intermitente», con VRB de 2 (RI 5; rango 0-27), y «dieta baja en grasas», con VRB de 1,16 (RI 0; rango 0-2). El término con mejor correlación a lo largo del tiempo fue «ayuno intermitente» (CS = 0,96), seguido de «dieta cetogénica» (CS = 0,91) y «dieta vegana» (CS = 0,85). CONCLUSIÓN: En España, el interés de la población sobre la información acerca de la dieta mediterránea es mayor que para otras dietas. Sin embargo, en los últimos años se ha producido un incremento progresivo en el interés, medido como VRB, en otras dietas, como la dieta cetogénica, la dieta vegana o el ayuno intermitente, y se ha producido una reducción en el interés por la dieta mediterránea. La dieta baja en grasas no genera interés en la población española

[Safety of insulin analogues: what to evaluate, how to do it, and how to interpret the results]. / Seguridad de los análogos de insulina: qué evaluar, cómo hacerlo y cómo interpretar los resultados.

The widespread use of insulin analogues is based not only on the pharmacokinetics of these preparations, which is much closer to the physiology of insulin secretion under normal conditions, but also on their safety and effectiveness. The publication of a possible association between the use of a long-acting insulin analogue (glargine) and breast cancer has caused uneasiness among the medical community regarding the safety of these analogues. The mechanism of increased tumor activity of insulin analogues is explained by the fact that they act through insulin receptors (IR) and insulin-like growth factor-1 (IGF-1R), stimulating cell growth and inhibiting apoptosis. There are two major mechanisms: an increase in the binding time of insulin to IR and increased activation of IGF-1R. Therefore, to evaluate the safety of an analogue, the slower dissociation rate from its insulin receptor must be excluded, as well as the increased affinity for the IGF-1 receptor. This is equivalent to an index of mitogenic/metabolic activity of less than 1. These aspects can only be evaluated through study of cell lines and animal testing, which are reductionist models that cannot always be extrapolated to humans. To date, there are no data to question the safety of insulin analogues in general. However, the results of observational studies and some in vitro studies, suggesting a potential risk of mitogenicity with the administration of glargine, have caused some alarm among the medical community. Until now, there are no data to refute or confirm this risk and, therefore, evaluation of the existing data is crucial to obtain objective information.

Transexualidad: transiciones, detransiciones y arrepentimientos en España / Transsexuality: Transitions, detransitions, and regrets in Spain

INTRODUCCIÓN: La demanda de atención sanitaria a personas transexuales o con incongruencia de género ha aumentado en los últimos años, sobre todo a expensas de jóvenes y adolescentes. También en paralelo ha aumentado el número de personas que refieren una pérdida o modificación en el sentimiento de género inicialmente expresado. Aunque siguen siendo minoría, nos enfrentamos cada vez más a casos complejos de personas transexuales que solicitan detransicionar y revertir los cambios conseguidos por arrepentimientos. OBJETIVO: Relatar nuestra experiencia con un grupo de personas transexuales en fase de detransición. Analizar su experiencia personal y los conflictos generados y reflexionar sobre estos procesos nunca antes descritos en España. MATERIAL Y MÉTODOS: Cohorte de 796 personas con incongruencia de género atendidas desde enero de 2008 hasta diciembre de 2018 en la Unidad de Identidad de Género del departamento Valencia Doctor Peset. De los 8 casos documentados de detransición y/o desistencia se relatan los 4 más representativos y que consideramos más ilustrativos de esta realidad. RESULTADOS: Las causas observadas que motivaron su detransición fueron la desistencia identitaria, las variantes de género no binarias, la psicomorbilidad asociada y la confusión entre identidad y orientación sexual. CONCLUSIÓN: La detransición es un fenómeno de presentación creciente que conlleva problemas clínicos, psicológicos y sociales. Una incorrecta evaluación y recurrir a la medicalización como única vía de mejora de la disforia en algunos jóvenes puede conducir a posteriores detransiciones. Es fundamental una atención integral dentro de un equipo multidisciplinar con experiencia. A falta de más estudios que determinen posibles factores predictivos de detransición, es recomendable proceder con prudencia en casos de historias identitarias atípicas

¿De qué nos sirve evaluar las tendencias del perfil glucémico ambulatorio? / Is it worth evaluating home blood glucose patterns?

El perfil glucémico ambulatorio es un instrumento utilizado para detectar tendencias glucémicas a partir de datos de un paciente determinado, registrados mediante análisis de glucemia capilar o bien, de forma más habitual, mediante monitorización continua de glucosa. Este instrumento analiza las variaciones de las glucemias obtenidas a lo largo de un número determinado de días, y las expresa en función de la hora del día con ayuda de la mediana y los percentiles 10, 25, 75 y 90. Es de gran utilidad para identificar tendencias glucémicas en diferentes momentos del día, para cuantificar variabilidad glucémica y para estratificar el riesgo de hipoglucemias en función de las horas. Debe complementarse con el análisis del registro individual de glucemias, ingestas y ejercicio para de esta manera detectar posibles causas de variabilidad y corregirlas

The ambulatory glucose profile is an instrument used to detect blood glucose patterns from patient results by recording blood glucose results or, more usually, by continuous glucose monitoring. This instrument analyzes the changes in glucose levels obtained over a number of days, and expresses the data, depending on the time of the day, using the median and the 10th, 25th, 75th and 90th percentiles. It is very useful for identifying glycemic patterns over the day, to quantify blood glucose variability, and to classify hypoglycemia risk according to time. This should be complemented with the analysis of individual blood glucose data, diet, and exercise, to detect potential causes of variability and correct them

A novel mutation in DAX1 (NR0B1) causing X-linked adrenal hypoplasia congenita: clinical, hormonal and genetic analysis.

The association of primary adrenal insufficiency and hypogonadotropic hypogonadism is extremely infrequent in daily clinical practice. Differential diagnosis includes X-linked adrenal hypoplasia congenita, a genetic disease characterized by an alteration in the formation of the adrenal glands and the hypothalamus-pituitary-gonadal axis. The gene responsible is DAX1 (NR0B1). The most common form of clinical presentation is neonatal primary adrenal insufficiency and complete hypogonadotropic hypogonadism. Members of a single family often present the same clinical form, although there may be relatives affected with different clinical symptoms. The aim of this study is to characterize clinically and genetically a family affected by different forms of hypogonadotropic hypogonadism and/or primary adrenal insufficiency. We describe a family with three members affected, two adults and a neonate. The way of presentation of the adults was neonatal primary adrenal insufficiency and hypogonadotropic hypogonadism (one complete and another presenting as interrupted puberty). The genetic study revealed a new mutation in DAX1, p.Q76X gene (c.C226T), resulting in a truncated protein of 76 amino acids, the same in all three affected male patients and in the asymptomatic women of the family. These cases further expand the number of DAX1 mutations reported, as well as the description of infrequent forms of presentation of this disease as interrupted puberty.

Obesity and overweight prevalences in rural and urban populations in East Spain and its association with undiagnosed hypertension and Diabetes Mellitus: a cross-sectional population-based survey.

BACKGROUND: An increase in the number of overweight and obese subjects in the general population has been observed.The aim of this study was to determine the prevalence of overweight and obese subjects in the general population and its association with undiagnosed pathologies, such as diabetes mellitus [DM] and hypertension [HT], by taking age, gender and place of residence [rural or urban] into account. FINDINGS: A cross-sectional population-based survey was conducted in Castellón, East Spain in 2005-2006. The sample included 2,062 participants aged 18-94 years. Weight, height, blood pressure and glycaemia values were recorded, and information about gender, age and place of residence was obtained. Overweight, obesity, and undiagnosed HT and DM prevalences were calculated. Multiple regression analyses were done to assess the association of overweight/obesity with undiagnosed HT and DM by adjusting for age, gender and place of residence.The overall overweight, obesity, and undiagnosed HT and DM prevalences were 39.9% [95% CI:37.3-42.0], 25.9% [95% CI:24.0-27.9], 9.0% [95% CI:7.8-10.4] and 12.6% [95% CI:11.2-14.1], respectively. We identified various independent risk factors; those relating to overweight were increasing age, male gender and rural residential area, while that relating to obesity was increasing age. Compared to normal weight adults, the Relative Prevalence Ratio (RPR) for subjects who were overweight and had HT was 2.00 [95% CI:1.21-3.32]; that for obesity and HT was 1.91 [95% CI:1.48-2.46], and it was 1.50 [95% CI:1.25-1.81] for obesity and DM. CONCLUSION: Overweight and obesity prevalences, and their association with undiagnosed DM and HT, are high in our study population.
