Determinants of Circulating 25-Hydroxyvitamin D and bone Mineral Density in Young Physicians

ObjectiveTo examine determinants of serum 25-hydroxyvitamin D [25(OH)D] and bone mineral density (BMD) in young physicians, a group not well studied previously.MethodsWe analyzed data from a questionnaire completed by young physicians as well as results of serum 25(OH)D, serum parathyroid hormone, and BMD measurements.ResultsAmong 104 study subjects, 42% were white, 46% were Asian, 12% were “other” (10 Hispanic and 2 African American subjects), and 75% were women. The mean age and body mass index (BMI) were 28.1 years and 23.0 kg/m², respectively. White subjects had a higher mean serum 25(OH)D level (27.3 ng/mL) than did Asian subjects (15.9 ng/mL) and other subjects (22.3 ng/mL) (P < .0001). White subjects tended to have higher Z-scores than Asian subjects and other subjects for the hip (P = .06), trochanter (P = .08), and lumbar spine (P = .08). The serum 25(OH)D level was negatively associated with serum parathyroid hormone (r = -0.44; P < .01) but not with BMD. The prevalence of vitamin D insufficiency [serum 25(OH)D < 30 ng/mL, 77% for the entire group] was higher (P < .01) in Asian subjects (93%) than in white subjects (61%) and other subjects (73%). Significant determinants of serum 25(OH)D included age, ethnicity, exposure to sunlight, use of vitamin D supplements, and family history of osteoporosis (P < .05 for all), and together with sex, calcium supplements, exercise, and BMI, these factors explained 49% of serum 25(OH)D level variability. Significant determinants of low BMD (osteopenia plus osteoporosis, prevalence 37.5%) included sex (P = .002) and BMI (P < .0001) but not serum 25(OH)D; Asian ethnicity reached borderline significance (P = .088). Age, sex, ethnicity, smoking, and BMI explained 20% to 30% of the Z-score variations.ConclusionIn young physicians with a healthful lifestyle, determinants of low serum 25(OH)D and BMD included modifiable risk factors. Vitamin D insufficiency and low BMD could be important contributors to future osteoporotic fractures in this population. (Endocr Pract. 2012;18:219-226)     

Allergic diseases and asthma in the family predict the persistence and onset-age of asthma: a prospective cohort study

BackgroundFamily history of asthma and other allergic diseases have been linked to the risk of childhood asthma previously, but little is known about their effect on the age-of-onset and persistency of asthma until young adulthood.MethodsWe assessed the effect of the family history of asthma and allergic diseases on persistent vs. transient, and early- vs. late-onset persistent asthma in The Espoo Cohort Study 1991–2011, a population-based cohort study of 1623 subjects (follow-up rate 63.2%). The determinants were any family history (any parent or sibling); maternal; paternal; siblings only; parents only; and both siblings and parents. Analyses were conducted separately for asthma and allergic diseases while taking the other disease into account as a confounding factor. The outcomes were persistent, transient, early-onset persistent (<13 years) and late-onset persistent asthma. Adjusted risk ratios (RR) were calculated applying Poisson regression. Q-statistics were used to assess heterogeneity between RRs.ResultsFamily history was associated with the different subtypes but the magnitude of effect varied quantitatively. Any family history of asthma was a stronger determinant of persistent (adjusted RR = 2.82, 95% CI 1.99-4.00) than transient asthma (1.65, 1.03-2.65) (heterogeneity: P = 0.07) and on early-onset than late-onset persistent asthma. Also any family history of allergic diseases was a stronger determinant of persistent and early-onset asthma. The impact of paternal asthma continued to young adulthood (early-onset: 3.33, 1.57-7.06 vs. late-onset 2.04, 0.75-5.52) while the influence of maternal asthma decreased with age (Early-onset 3.94, 2.11-7.36 vs. Late-onset 0.88, 0.28-2.81). Paternal allergic diseases did not follow the pattern of paternal asthma, since they showed no association with late-onset asthma. Also the effect estimates for other subtypes were lower than in other hereditary groups (persistent 1.29, 0.75-2.22 vs. transient 1.20, 0.67-2.15 and early-onset 1.86, 0.95-3.64 vs. late-onset 0.64, 0.22-1.80).ConclusionsFamily history of asthma and allergic diseases are strong determinants of asthma, but the magnitude of effect varies according to the hereditary group so that some subtypes have a stronger hereditary component, and others may be more strongly related to environmental exposures. Our results provide useful information for assessing the prognosis of asthma based on a thorough family history.     

Future of cancer incidence in Shanghai,China: Predicting the burden upon the ageing population

AimThe age-specific cancer patterns have changed significantly over the last few decades in urban Shanghai. Predicting the cancer incidence in an ageing population can help to anticipate future resource needs, evaluate primary prevention strategies, and inform further research studies.Materials and MethodsAnnual cancer cases and population data from 1988 to 2013 were collected from Shanghai Cancer Registry. A Bayesian age-period-cohort model was applied to project the future cancer incidence with demographical changes from 2014 to 2025.ResultsFrom 1988 through 2013, the urban population aged < 65 years decreased by 19.5%, while the population aged ≥ 65 years increased by 58.4%. In the same period, cancer cases increased by 66.0% (from 8315 to 13,806) and 88.6% (from 7448 to 14,048) in these two populations, respectively. From 2014–2025, the population size is expected to decrease by an additional 29.6% in people aged < 65 years, while it will increase by an additional 68.3% in people aged ≥ 65 years. Correspondingly, the model predicts an 87.5% and 143.4% increase in cancer cases for these two populations, respectively. The most pronounced increase was found in thyroid cancer in both sexes, followed by prostate, kidney, and colon cancer in men. In women, lung, kidney, and cervical cancer in women was expected to increase.ConclusionsThe number of cancer cases in urban Shanghai, especially in older people, is expected to significantly increase in the next decade. Particular strategies targeting the elderly are required to combat the cancers.     

Prevalence of Type 2 Diabetes Mellitus In Patients With Primary Hyperparathyroidism

IntroductionTo determine the prevalence of type 2 diabetes mellitus (DM) in patients with primary hyperparathyroidism.MethodsPrevalence of type 2 DM in 609 patients with surgically verified primary hyperparathyroidism presenting between 1992 and 2003 in a tertiary care hospital setting was assessed retrospectively and compared with published data of type 2 DM prevalence in Michigan’s general population. Diagnosis of type 2 DM was made on the basis of documentation in the medical record of fasting or random blood glucose level thresholds according to the 1997 American Diabetes Association criteria, history of diabetes mellitus, or therapy with antidiabetic medications.ResultsThe crude prevalence rate of type 2 DM in patients with primary hyperparathyroidism was significantly higher than the prevalence in the Michigan general population (15.9% vs 7.8%, respectively; P < .001). However, this difference was not significant after age stratification except for the age group of 64 to 75 years. Because of the differential distribution of participants across age categories in the 2 groups, a standardized prevalence ratio (SPR) was estimated to account for the variance. After adjustment, there was no significant difference in the prevalence of DM between patients with primary hyperparathyroidism and the control population (SPR, 1.19 [95% confidence interval, 0.96-1.45]) except in men.ConclusionThe reported higher prevalence of type 2 DM in patients with primary hyperparathyroidism could not be confirmed in this large cohort of patients except for in older patients and in men. Because of the retrospective nature the study and the lack of appropriate controls, further studies are needed to confirm or refute these findings. (Endocr Pract. 2008;14:69-75)     

Disparities in survival improvement for U.S. childhood and adolescent cancer between 1995 and 2019: An analysis of population-based data

BackgroundAlthough treatment advances have increased childhood and adolescent cancer survival, whether patient subgroups have benefited equally from these improvements is unclear.MethodsData on 42,865 malignant primary cancers diagnosed between 1995 and 2019 in individuals ≤ 19 years were obtained from 12 Surveillance, Epidemiology, and End Results registries. Hazard ratios (HRs) and 95 % confidence intervals (CIs) for cancer-specific mortality by age group (0–14 and 15–19 years), sex, and race/ethnicity were estimated using flexible parametric models with a restricted cubic spline function in each of the periods: 2000–2004, 2005–2009, 2010–2014 and 2015–2019, versus 1995–1999. Interactions between diagnosis period and age group (children 0–14 and adolescents 15–19 years at diagnosis), sex, and race/ethnicity were assessed using likelihood ratio tests. Five-year cancer-specific survival rates for each diagnosis period were further predicted.ResultsCompared with the 1995–1999 cohort, the risk of dying from all cancers combined decreased in subgroups defined by age, sex and race/ethnicity with HRs ranging from 0.50 to 0.68 for the 2015–2019 comparison. HRs were more variable by cancer subtype. There were no statistically significant interactions by age group (P_interaction=0.05) or sex (P_interaction=0.71). Despite non-significant differences in cancer-specific survival improvement across different races and ethnicities (P_interaction=0.33) over the study period, minorities consistently experienced inferior survival compared with non-Hispanic Whites.ConclusionsThe substantial improvements in cancer-specific survival for childhood and adolescent cancer did not differ significantly by different age, sex, and race/ethnicity groups. However, persistent gaps in survival between minorities and non-Hispanic Whites are noteworthy.     

A retrospective analysis of human papillomavirus (HPV) prevalence and genotype distribution among 25,238 women in Shanghai,China revealed the limitations of current HPV-based screening and HPV vaccine

BackgroundTo determine the human papillomavirus (HPV) type-specific prevalence and distribution among women with various age and cervical lesions in Shanghai, China. And to evaluate the carcinogenicity of different high-risk HPV (HR-HPV) and the efficacy of HR-HPV testing and HPV vaccine.MethodsThe clinical data from 25,238 participants who received HR-HPV testing (HPV GenoArray test kit, HybriBio Ltd) at the Affiliated Hospital of Tongji University from 2016 to 2019 were reviewed and analyzed using SPSS (version 20.0, Tongji University, China).ResultsThe overall prevalence of HPV was 45.57% in the study population, of which 93.51% were found HR-HPV infection. The three most prevalent HR-HPV genotypes were HPV 52 (22.47%), 16 (16.4%) and 58 (15.93%) among HPV-positive women, and HPV 16 (43.30%), 18 (9.28%) and 58 (7.22%) in women with histologically confirmed cervical cancer (CC). 8.25% of CC were found to be HPV negative. Only 83.51% of CC cases were related to the HPV genotypes covered by nine-valent HPV vaccine. HPV prevalence and genotype distribution varied with age and cervical histology. The odds ratios (OR) of HR-HPV for CC were also different, among which the top three types were HPV 45 [OR= 40.13, 95% confidence intervals (CI) 10.37–155.38], 16 (OR=33.98, 95%CI 15.90–72.60) and 18 (OR=21.11, 95%CI 8.09–55.09). The increase in the types of HPV infection did not increase the risk of CC correspondingly. As the primary cervical screening method, HR-HPV testing showed the high sensitivity (93.97%, 95%CI 92.00–95.49) but low specificity (42.82%, 95%CI 41.81–43.84).ConclusionsOur study provide the comprehensive epidemiological data on HPV prevalence and genotype distribution among Shanghai women with various cervical histology, which can not only serve as a significant reference for clinical practice, but also implicated the need of more effective CC screening methods and HPV vaccine covering more subtypes.     

A Four-Way Comparison of Cardiac Function with Normobaric Normoxia,Normobaric Hypoxia,Hypobaric Hypoxia and Genuine High Altitude

BackgroundThere has been considerable debate as to whether different modalities of simulated hypoxia induce similar cardiac responses.ResultsAll 14 subjects completed the experiment at GHA, 11 at NN, 12 under NH, and 6 under HH. The four groups were similar in age, sex and baseline demographics. At baseline rest right ventricular (RV) systolic pressure (RVSP, p = 0.0002), pulmonary vascular resistance (p = 0.0002) and acute mountain sickness (AMS) scores were higher and the SpO₂ lower (p<0.0001) among all three hypoxic groups (GHA, NH and HH) compared with NN. At both 15 minutes and 120 minutes post exercise, AMS scores, Cardiac output, septal S’, lateral S’, tricuspid S’ and A’ velocities and RVSP were higher and SpO₂ lower with all forms of hypoxia compared with NN. On post-test analysis, among the three hypoxia groups, SpO₂ was lower at baseline and 15 minutes post exercise with GHA (89.3±3.4% and 89.3±2.2%) and HH (89.0±3.1 and (89.8±5.0) compared with NH (92.9±1.7 and 93.6±2.5%). The RV Myocardial Performance (Tei) Index and RVSP were significantly higher with HH than NH at 15 and 120 minutes post exercise respectively and tricuspid A’ was higher with GHA compared with NH at 15 minutes post exercise.ConclusionsGHA, NH and HH produce similar cardiac adaptations over short duration rest despite lower SpO₂ levels with GHA and HH compared with NH. Notable differences emerge following exercise in SpO_2, RVSP and RV cardiac function.     

The association between content of the elements S,Cl, K,Fe, Cu,Zn and Br in normal and cirrhotic liver tissue from Danes and Greenlandic Inuit examined by dual hierarchical clustering analysis

ProjectMeta-analysis of previous studies evaluating associations between content of elements sulphur (S), chlorine (Cl), potassium (K), iron (Fe), copper (Cu), zinc (Zn) and bromine (Br) in normal and cirrhotic autopsy liver tissue samples.ProcedureNormal liver samples from 45 Greenlandic Inuit, median age 60 years and from 71 Danes, median age 61 years. Cirrhotic liver samples from 27 Danes, median age 71 years. Element content was measured using X-ray fluorescence spectrometry. Statistics: Dual hierarchical clustering analysis, creating a dual dendrogram, one clustering element contents according to calculated similarities, one clustering elements according to correlation coefficients between the element contents, both using Euclidian distance and Ward Procedure.ResultsOne dendrogram separated subjects in 7 clusters showing no differences in ethnicity, gender or age. The analysis discriminated between elements in normal and cirrhotic livers. The other dendrogram clustered elements in four clusters: sulphur and chlorine; copper and bromine; potassium and zinc; iron. There were significant correlations between the elements in normal liver samples: S was associated with Cl, K, Br and Zn; Cl with S and Br; K with S, Br and Zn; Cu with Br. Zn with S and K. Br with S, Cl, K and Cu. Fe did not show significant associations with any other element.ConclusionsIn contrast to simple statistical methods, which analyses content of elements separately one by one, dual hierarchical clustering analysis incorporates all elements at the same time and can be used to examine the linkage and interplay between multiple elements in tissue samples.

Prevalence of Type 2 Diabetes among High-Risk Adults in Shanghai from 2002 to 2012

Objective

The objective of this study was to evaluate the trend and prevalence of prediabetes and diabetes among high-risk adults in Shanghai from 2002 to 2012.

Methods

From 2002 to 2012, 10043 subjects with known risk factors for diabetes participated in the diabetes-screening project at the Shanghai Sixth People’s Hospital of Shanghai Jiao Tong University. All participants were asked to complete a nurse-administered standard questionnaire concerning age, sex, smoking status, and personal and family histories of diabetes, cardiovascular disease, stroke, hypertension and other diseases. The participants’ body mass index scores, blood pressures and blood glucose levels at 0, 30, 60, 120 and 180 min were measured in response to a 75 g oral glucose tolerance test.

Results

The overall prevalence of diabetes increased from 27.93% to 34.78% between 2002 and 2012 in high-risk subjects. The study also showed that the prevalence increased much faster in male compared to female subjects. Specifically, an increased rate was seen in middle-aged men, with no change observed in middle-aged females over the eleven-year period.

Conclusion

This study showed that sex, age, parental diabetic history, and being overweight were associated with an increased risk for diabetes in high-risk people. Therefore, as prediabetes and diabetes are highly prevalent in people with multiple diabetes risk factors in Shanghai, screening programs targeting these individuals may be beneficial.     

上海市杨浦区社区2型糖尿病患者周围神经病变患病率调查及其影响因素分析

摘要 目的：调查上海市杨浦区社区2型糖尿病（T2DM）患者周围神经病变（DPN）患病率,并分析其影响因素。方法：于2019年3月~2020年3月在上海市杨浦区所辖社区中随机选取5个社区,采用分层随机抽样法从每个社区选取100例T2DM患者进行调查,统计T2DM患者DPN患病率,采用多因素Logistic回归分析DPN发生的影响因素。结果：本次研究共发放500份调查问卷,回收498份,回收率为99.60%（498/500）,其中DPN患者222例,DPN发生率为44.58%（222/498）,纳为DPN组,276例未发生DPN纳为非DPN组。单因素分析结果显示：DPN组与非DPN组在腰围、合并糖尿病视网膜病变（DR）、合并下肢血管病变（PVD）、吸烟史、高血压、脑梗死病史、文化程度、婚姻状况、收缩压（SBP）、空腹血糖（FPG）、葡萄糖达标时间百分比（TIR）、载脂蛋白B、尿酸方面比较有差异（P<0.05）。进一步多因素Logistic回归分析结果显示：合并DR、合并PVD、有吸烟史、有脑梗死病史、婚姻状况为未婚/离异/丧偶、FPG水平较高是T2DM患者发生DPN的危险因素（P<0.05）。结论：T2DM患者中DPN的患病率较高,合并DR、PVD、吸烟史、脑梗死病史以及婚姻状况是DPN发生的影响因素,应重视DPN筛查并进行干预,针对上述影响因素对T2DM患者开展健康宣教,减少DPN的发生。     

Serum levels of GDF15 are reduced in preeclampsia and the reduction is more profound in late-onset than early-onset cases

BackgroundPreeclampsia is a pregnancy specific disorder affecting 3–5% of pregnancies worldwide. It is clinically divided into early-onset and late-onset subtypes. Placental factors are involved in the pathogenesis of preeclampsia. Growth differentiation factor 15 (GDF15), a protein of the transforming growth factor beta superfamily, is highly expressed in the placenta. However, it is unclear whether the circulating levels of GDF15 are altered in preeclampsia at the time of or prior to disease presentation.MethodsSerum samples across three trimesters from 29 healthy pregnancies, third trimester sera from 34 women presenting with preeclampsia (early-onset n = 16, late-onset n = 18) and 66 gestation-age-matched controls, and sera at 11–13 weeks of pregnancy from women who later did (n = 36) or did not (n = 33) develop late-onset preeclampsia, were examined for GDF15 by ELISA.ResultsSerum GDF15 levels increased significantly with gestation in normal pregnancy. Serum GDF15 was significantly reduced in the third trimester in women presenting with preeclampsia compared to their gestation-age-matched controls. This reduction was apparent in both early-onset and late-onset subtypes, but it was more profound in late-onset cases. At 11–13 weeks of gestation, however, serum levels of GDF15 were similar between women who subsequently did and did not develop late-onset preeclampsia.ConclusionSerum GDF15 increased with gestation age, reaching the highest level in the third trimester. Serum GDF15 was significantly reduced in the third trimester in women presenting with preeclampsia, especially in late-onset cases. However, serum GDF15 was not altered in the first trimester in women destined to develop late-onset preeclampsia.     

Colonización por Pneumocystis jirovecii en mujeres gestantes y recién nacidos en Lima,Perú

BackgroundPneumocystis jirovecii primary infection occurs asymptomatically before 6 months of age, suggesting that the infection is acquired very early in life. Furthermore, Pneumocystis pneumonia has been described in newborns, which emphasizes the importance of studying Pneumocystis colonization in mother-infant pairs.AimsTo evaluate the prevalence of Pneumocystis colonization among pregnant women and to determine the potential transplacental transmission.MethodsA cross-sectional study was carried out on HIV-negative women over 18 years-old, and 37 or more weeks of pregnancy attending Hospital Cayetano Heredia Maternity unit during 2016-2017. Clinical and demographical information was collected on them and their newborns. Oropharyngeal washes, nasal swabs, and placenta samples were collected from women, as well as a nasopharyngeal aspirate and nasal swab from newborns. All respiratory samples were analysed by nested-PCR for the detection of Pneumocystis. Placenta samples from women with a positive PCR result in their respiratory samples were also analysed by nested-PCR.ResultsOf the 92 pregnant women included, five of them (5.43%) were colonized by Pneumocystis. Pneumocystis DNA was not found in any of the 87 available newborn samples or in the placentas of the five women who had a positive result by PCR in their upper respiratory samples.ConclusionsIt was found that 5.43% of the pregnant women were colonized by Pneumocystis, there was no evidence of any role of this colonization in the transmission to their newborns, since none of them tested positive for Pneumocystis.     

Metabolic Syndrome in Primary Gout

Background and Objectives. Primary gout has traditionally been associated with obesity, arterial hypertension, and abnormal lipid and glucose homeostasis, but we do not know the prevalence of these vascular risk factors in patients with primary gout from a Mediterranean country. Patients and Method. All patients with primary gout and 2 or more acute arthritis episodes documented by a physician were selected for the study. The diagnosis of MS required ≥3 criteria (ATP III). Patients were classified in two groups: decreased (underexcretors) and normal (normoexcretors) uric acid excretion related to serum urate levels. Results. One hundred and four patients (mean age, 59 years; 100 males) with primary gout were included in the study. MS was diagnosed in 38 subjects (37%). The most frequent triad defining MS was an increased waist circumference, blood pressure, and trygliceride levels. The prevalence of type 2 diabetes mellitus (T2D) was significantly higher in patients with the MS (21/38, 55%) as compared with subjects without the MS (3/66, 5%; p < 0.001). Mean serum urate level in patients with and without MS was identical (8.1 mg/dL), but mean 24-hour uric acid excretion was significantly lower in the former than in the latter (444 ± 110 mg/24-hour/1,73 m² versus 546 ± 221 mg/day/1,73 m²; p = 0.009). Conclusions. The condition of the MS occurs in about one-third of the patients with primary gout. Increased waist circumference, blood pressure, and triglycerides levels is the most frequent MS triad. Diminished urinary uric acid excretion is more severe in gout patients with the MS.     

Hormone Replacement Therapy in Children with Hypogonadotropic Hypogonadism: Where do we Stand?

ObjectiveTo characterize hormone replacement therapy in a cohort of adolescent males and females with hypo-gonadotropic hypogonadism (HH) with a focus on changes in management during the past 10 years.MethodsMedical records of patients followed for HH during the past 10 years were reviewed.ResultsA total of 45 patients (22 female: 23 male) with HH were identified. The average age at HH diagnosis was 14.48 ± 2.02 years in females and 14.89 ± 1.64 years in males (P = .53). In females, the average age of pubertal induction was 14.53 ± 1.86 years. Conjugated equine estrogen was used in 54.5%, transdermal estradiol in 41%, and oral estradiol in 4.5%. The average duration to cycling was 1.96 ± 0.78 years. A progressive increase in the use of transdermal estradiol was noted over time, with 100% of females being started on this regimen since 2008. In males, the average age of induction was 15.22 ± 1.41 years. All were started on intramuscular testosterone cypionate at various doses. The average duration to full adult replacement was 1.95 ± 0.51 years.ConclusionThere is no current standard of care to guide pubertal induction in adolescents with HH. However, a significant increase in the use of transdermal estrogen was noted in females during the past 10 years. While much less variability in pubertal induction was seen in males, wide disparities in doses and escalation schedules were found. Prospective studies aimed at elucidating optimal strategies for sex steroid replacement in this pediatric population are badly needed. (Endocr Pract. 2013;19:968-971)

Body mass index and relative handgrip strength are associated with the prevalence of hypertension in Korean elderly: Korean national fitness assessment in 2019

[Purpose]This study aimed to analyze the prevalence of hypertension according to the body mass index (BMI) and relative handgrip strength (RHGS) among elderly individuals in Korea. [Methods]We analyzed the data of 44,183 Korean elderly individuals over 65 years old (men: n = 15,798, age = 73.31 ± 5.04 years, women: n = 28,385, age = 72.14 ± 5.04 years) obtained from the Korean National Fitness Assessment in 2019. All the participants were categorized into three groups according to the BMI and RHGS; additionally, one-way ANOVA and logistic regression analysis were performed. [Results]Overweight (men: 1.16 odds ratio [OR] 1.06–1.26, 95% confidence interval [CI]; women: 1.15 OR, 1.07–1.23 95% CI) and obese (men: 1.54 OR, 1.42–1.66 95% CI; women: 1.44 OR, 1.36–1.53 95% CI) elderly individuals showed a higher prevalence of hypertension than elderly individuals with normal weight, after controlling for age. In men, a lower RHGS was associated with a higher prevalence of hypertension after controlling for age (weak RHGS: 1.09 OR, 1.00–1.17 95% CI; middle RHGS: 1.21 OR, 1.12–1.31 95% CI vs. strong RHGS). [Conclusion]A higher BMI was associated with the prevalence of hypertension in the elderly Korean population. In addition, a lower RHGS was associated with the prevalence of hypertension in elderly Korean men.     

Inequality in Diabetes-Related Hospital Admissions in England by Socioeconomic Deprivation and Ethnicity: Facility-Based Cross-Sectional Analysis

ObjectiveTo investigate the effect of social deprivation and ethnicity on inpatient admissions due to diabetes in England.DesignFacility-based cross-sectional analysis.SettingNational Health Service (NHS) trusts in England reporting inpatient admissions with better than 80% data reporting quality from 2010–2011 (355 facilities).ParticipantsNon-obstetric patients over 16 years old in all NHS facilities in England. The sample size after exclusions was 5,147,859 all-cause admissions.ResultsThere were 445,504 diabetes-related hospital admissions in England in 2010, giving a directly (age-sex) standardized rate of 1049.0 per 100,000 population (95% confidence interval (CI): 1046.0–1052.1). The relative risk of inpatient admission in the most deprived quintile was 2.08 times higher than that of the least deprived quintile (95% CI: 2.02–2.14), and the effect of deprivation varied across ethnicities. About 30.1% of patients admitted due to diabetes were readmitted at least once due to diabetes. South Asians showed 2.62 times (95% CI: 2.51 – 2.74) higher admission risk. Readmission risk increased with IMD among white British but not other ethnicities. South Asians showed slightly lower risk of readmission than white British (0.86, 95% CI: 0.80 – 0.94).ConclusionsMore deprived areas had higher rates of inpatient admissions and readmissions due to diabetes. South Asian British showed higher admission risk and lower readmission risk than white British. However, there was almost no difference by ethnicity in readmission due to diabetes. Higher rates of admission among deprived people may not necessarily reflect higher prevalence, but higher admission rates in south Asian British may be explained by their higher prevalence because their lower readmission risk suggests no inequality in primary care to prevent readmission. Better interventions in poorer areas, are needed to reduce these inequalities.
