New findings on type 2 diabetes in first-generation Chinese migrants settled in Italy: Chinese in Prato (CHIP) cross-sectional survey

BACKGROUND

Chinese people are one of the fastest growing immigrant populations in Europe, and their health has become a key issue to host nations. Although type 2 diabetes (T2DM) is a big burden among migrant populations, data on Chinese immigrants in Europe are limited.

METHODS

A cross-sectional survey was performed in 2014, adopting principles of community-based participatory research to investigate T2DM, diagnosed by the American Diabetes Association fasting criteria, in Chinese first-generation migrants aged 16 to 59 years settled in Prato (Italy). Association with different factors was investigated using logistic regression.

RESULTS

Of the 1608 participants, 177 had T2DM (11.0%), 119 being newly diagnosed (7.4%). Among subjects with diabetes, 58 (32.8%) were aware of the disease; among subjects with diabetes aware of their condition, 46 (79%) were treated with glucose lowering drugs. Age-standardized (World Health Organization 2001 population) prevalence of T2DM was 9.6% (95% CI 9.1 to 10.2%), being 12.0% (95% CI 11.0 to 12.9%) in men, and 7.8% (95% CI 7.1 to 8.4%) in women. At adjusted logistic regression, diabetes was associated with hypertension, current smoking, adiposity indices (waist circumference, waist-to-hip ratio, waist-to-height ratio, and body mass index), and high triglycerides. T2DM, adiposity indices, and high triglycerides were not associated with duration of stay in Italy.

CONCLUSIONS

The high prevalence of T2DM among first-generation Chinese immigrants in Europe stresses the need for specific health programs for T2DM early diagnosis, treatment, and prevention. There is an urgent need for policies to support this group because current policies will produce major social and economic costs. Copyright © 2016 John Wiley & Sons, Ltd.

Lifestyle and resulting body composition in young athletes

BACKGROUND

Key aspects in a lifestyle analysis are physical activity level and eating habits. An unhealthy lifestyle results in fat mass increase and in a predisposition to non-communicable chronic diseases even in young age. The purpose of this study was to investigate the lifestyle and body composition in young athletes.

METHODS

The subjects underwent to an assessment of body composition and they completed two questionnaires, one concerning the level of physical activity and the other regarding eating habits.

RESULTS

One hundred fifty-two young athletes (63 females and 89 males) aged 8 to 18 years (13.4±2.5 years, height 159±14 cm) were enrolled in this study. 80.3% of subjects were normal weight (13.4±2.6 years) and 19.7% subjects (13.5±2.5 years) were overweight or obese. Greater sedentary behaviors were found in the overweight or obese participants compared to normal weight (618±125 vs. 523±89 min; P<0.001) and a lower consumption of milk and yoghurt (5.0±3.2 vs. 6.9±4.1 times/week; P=0.031).

CONCLUSIONS

Although competitive sports often increase physical activity levels in young people, this activity does not seem to reach the daily recommended amount of physical activity during youth. Therefore, it is necessary to have a comprehensive approach to create a primary prevention strategy from even a young age.

Left ventricular remodeling and the athlete's heart, irrespective of quality load training

Background

Regular physical exercise determines a progressive increase of the cardiac mass known as adaptive hypertrophy. Up to now, two morphological echocardiographic heart patterns of athletes have been described by Morganroth in 1975: predominant augmentation of wall thickness, and major cavity size in chamber dimensions in the case of prevalent static or dynamic components. The aim of the study was to follow up the impact of physical training on heart morphology and function in a group of elite soccer and rugby players for at least five years.

Method

From January 1993 to December 2015 a group of 250 elite soccer players and 114 rugby players were examined: 78 soccer players and 60 rugby players were followed up for 5 years. They were matched with a control group.

Results

LV dimensions and LVMi were significantly higher in the athletes than in the inactive subjects (LVMi : 123.45; LVMi: 81.5 vs 94.36 g/m2 respectively). After the five-year follow up the athletes showed no significant modifications in cardiac dimensions: (LVDd from 52.00 ± mm to 52.90 ± mm; LVSd increased from 31.58 ± mm to 32.33 ± mm; Left Ventricular CMI from 120.77 to 121.45 g/m2;p = NS in soccer; from 50.43 ± mm to 52.22 ± mm; Left Ventricular Systolic diameter increased from 32.51 ± mm to 32.8 ± mm; Left Ventricular Mass index from 81,5 to 87,4 g/m2;p = NS and no significant enhancement of the aortic root diameter was observed (Aortic root: from 27.39 mm to 31.64 mm in soccer players; from 30,68 mm to 30.95 mm).

Conclusions

No significant differences were found among the athletes practicing sports with different workload components, and resistance training. In trained athletes the dimensions of the LV chamber and LVMi are generally within the upper limits of the normal range. After a five-year follow-up, the dimensions of the chambers of the heart remain within the normal range, despite being within the the upper limits. Regular physical exercise induces mild LV hypertrophy which therefore can be considered an adaptive consequence to stress-exercise.

Quality of life perception in type 2 diabetes

PURPOSE

Lifestyle analysis is often used for primary and secondary prevention in many chronic metabolic diseases, including diabetes. Questionnaires are simple and common methods for first investigation risk of factors related to the perception of quality of life (QoL). The present study evaluates the feasibility to use questionnaires for first investigation of risk factors, and ascertain whether the results of such questionnaires are associated with the perception of QoL.

METHODS

Validated questionnaires from the international ACSM guidelines were used to study a cohort of 142 consecutive type 2 diabetes patients (mean age: 66.1 years ± 10.9).

RESULTS

QoL perception was normal; BMI was compatible with overweight in 79.1% of subjects, and obesity in 20.9%. Cognitive abilities decreased with age and low consumption of dried fruit and legumes. There was evidence of a statistically significant association between BMI and QoL (rho = -0.18; p = 0.03).

CONCLUSIONS

Questionnaires are useful to assess lifestyle habits and highlight risks factors. Poor knowledge of patients' own chronic disease may contribute to a negative impact in diabetes.

Sexual Activity before Sports Competition: A Systematic Review

Sexual activity before competition has been considered as a possible cause for reduced performance since ancient Greece and Rome. Recently, the hypothesis that optimal sport performance could be influenced by a variety of factors including sexual activity before competition has been investigated. However, few scientific data are available, with the exception of anecdotal reports of individual experiences. The present systematic review focused on the current scientific evidence on the effects of sexual activity on sport performance regardless of sport type. Data were obtained following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, using PubMed/MEDLINE, ISI/Web of Science, the Cochrane Collaboration Database, Cochrane Library, Evidence Database (PEDro), Evidence Based Medicine (EBM) Search review, National Guidelines, ProQuest, and Scopus, all searched from inception further, to broaden the search, no time filter nor language restriction have been applied. Also, the gray literature was mined using Google Scholar. Only relevant scientific articles reporting outcomes of athletic performance after sexual activity were considered. The impact of sexual activity before a sport competition is still unclear, but most studies generally seem to exclude a direct impact of sexual activity on athletic aerobic and strength performance. The most important aspect seems to be the interval from the time of the sports competition that affects negatively the performance if it is shorter than 2 h. There are possible negative effects from some possible concurrent wrong behaviors such as smoking or alcohol abuse. There are no investigations about the effect of masturbation in this context. There is a need to clarify the effects of sexual activity on competition performance. The present evidence suggests that sexual activity the day before competition does not exert any negative impact on performance, even though high-quality, randomized controlled studies are urgently needed.

Integrated total body composition versus Body Mass Index in young athletes

BACKGROUND

The aim of this study was to assess if the evaluation of Body Mass Index is sufficient to define an overweight index in young athletes, or if a more effective evaluation is preferable in order to examine body fat mass, free-fat mass and hydration status in young athletes.

METHODS

Two hundred ninety-nine young athletes between the ages of 8 to 18 have been analyzed in this study. Data from evaluation in body composition of young athletes were studied and subdivided by age, sex and method used. In order to measure body composition in young people, the participants who attend our Department for sport eligibility examination, were evaluated through anthropometric measurements as far as, fat mass, fat-free mass and hydration status are concerned.

RESULTS

The statistical differences showed with Body Mass Index and body fat assessment reflect that more accurate evaluation is preferable: the normal-weight with Body Mass Index are 78.0%, overweight 18.7% and obese 3.3% respect to a 75.0%, 14.0% and 11.0% detected with a body fat evaluation (P<0.000); statistical differences have been found also subdividing the group per sex, higher in males (P=0.046) than to females (P<0.000). Bio-impedance data shown a statistical differences in young obese athletes.

CONCLUSIONS

The results obtained show clearly that the analysis of the Body Mass Index is not sufficient in young athletes. Therefore, for young athletes a full assessment of body composition would be appropriate to reduce classific-tion errors.

Female athletes and menstrual disorders: a pilot study

BACKGROUND

There is a greater incidence of menstrual disorders in female athletes than in their sedentary counterparts. The menstrual disorder is reported in female athletes suffering from athletic triad syndrome, while few data in those free of this syndrome are available. The study aims to ascertain the presence of menstrual disorders and the eventual relationship with myocardial performance in female athletes practicing different sports.

METHODS

A sample of 64 subjects aged 18.5±2 was selected and divided into 3 groups (37 subjects practicing rhythmic gymnastics, 11 swimmers, and 16 volleyball players). All underwent echocardiography, biompendance analysis, and answered a questionnaire.

RESULTS

All anthropometrics parameters were normal. Few athletes reported menstrual disorders. No association between the presence of menstrual disorders and BMI. All echo results were within the normal range. Cardiac Mass Index (CMI) was normal for all athletes despite in swimmers significantly higher values (90.64±14.9 g/m2) compared to the volleyball players (78.25±14.0 g/m2; p<.04) and rhythmic gymnasts (77.89±13.4 g/m2; p<.009) were found.

CONCLUSIONS

Despite menstrual disorders are represented among female athletes, the eventual relationship with the sport practiced is not so evident. Questionnaire should be used to identify menstrual disorders in non-elite athletically active females.

Lifestyle interventions in preventing new type 2 diabetes in Asian populations

The aim of this study was to review current evidence on interventional studies aimed at the prevention of type 2 diabetes in Asian population with lifestyle interventions. Prevalence of type 2 diabetes sharply increased in most Asian countries during the last decades. This issue has now also relevant implication for Europe where different surveys are also consistently revealing an higher prevalence of type 2 diabetes and other and major CVD risk factors among subjects originating from Asian Countries than in the native population. Nutrition and lifestyle transition seem to play a role in disclosing the predisposition for the development of type 2 diabetes and great interest is now shown toward the possibility to intervene with lifestyle intervention on at risk populations. A meta-analysis of Randomized Controlled Trials showed that lifestyle interventions are highly effective also in the Asian population. All studies were, however, conducted with an individual approach based on the identification of high-risk individuals. When ethnic minority groups have to be addressed, an approach directed to the community rather than to the individual might, however, be more effective. This review reinforces the importance for policy-makers to consider the involvement of the whole community of minority immigrant groups with lifestyle intervention programs.

Short-term prospective study of prescribed physical activity in kidney transplant recipients

Regular physical exercise plays a role in improving cardiovascular and muscular fitness in many metabolic diseases. This study aims to verify any possible benefits, including the eventual influence on any associated risk factors, in a group of kidney transplant recipients after a short period of personalized training programs with mixed exercises. In January 2013, at the Sports Medicine Center of the University of Florence, Italy, we began studying a group of 20 kidney transplant recipients. After 6 months of exercise, they underwent Cardiopulmonary Test (CPET), ECG, skin fold, bioimpedance analysis and stress test for the lower and upper limbs. EF increased significantly from 63.38 ± 4 to 67.30 ± 5.9 with p < 0.05; the anaerobic threshold improved from 14.48 ± 6.3 to 20.24 ± 3.7 (p < 0.05) with good stress tolerance, estimated by CR10 scale; weight decreased significantly (70.06-65.03 kg) as did skin folds at pectoral level (p < 0.002). Upper limb muscular strength increased significantly (p < 0.005). Regular mixed exercise is a proposed program in post-transplant syndrome with the expectation of improving cardiovascular performance and enhancing exercise tolerance. Muscle strength improves with physical fitness with consequent reduction of risk factors linked to visceral fat. Proof of an eventual positive impact on other complex aspects associated with post-transplant metabolic syndrome will require a longer follow-up.

Carotid Intima-Media Thickness in Master Athletes

Background:

Carotid Intima Media Thickness (IMT) is currently used to assess the relationship between progression of coronary and systemic atherosclerosis. To date, however, the possible impact of regular physical activity (PA) on this parameter has not been well estimated.

Objectives:

Our study aims to examine this aspect especially in the absence of cardiovascular (CV) risk factors.

Patients and Methods:

100 master athletes (MA) and 51 sedentary controls (SC) were enrolled. They were evaluated by echo test with dedicated software (QIMT-Esaote) for IMT, and Bruce protocol and 2D echocardiography for cardiac hemodynamic parameters.

Results:

All values were within normal range. Left IMT mean values were significantly higher than right IMT values in both MA and SC groups (MA: IMT left 635 ± 104 µ, IMT right 614 ± 104 µ and mean IMT 624 ± 91.9 µ; SC: IMT left 633 ± 78 µ, IMT right 622 ± 90 µ and mean IMT 627 ± 78.1 µ). A positive relationship was found in both groups between IMT mean values and age (P < 0.01) and between IMT mean values and peak systolic blood pressure (MA: 0.28 R, P < 0.01; SC: 0.32 R, P < 0.05). At rest, only in MA was a significant relationship evident, between mean arterial pressure value and IMT (P < 0.01).

Conclusions:

In the absence of CV risk factors, only age is associated with a slight increase of wall carotid thickening. The data are indicative of a physiological increase in IMT, as a consequence of increased peak effort systolic pressure after regular PA in athletes.

Evaluation of physical activity and dietary behaviors in young athletes: a pilot study

BACKGROUND

The aim of this study was to evaluate the lifestyle based on the physical activity and eating habits of young athletes.

METHODS

In order to measure physical activity and eating habits in young people, 922 young athletes between the ages of 8 to 18 have been analyzed in this study. The participants were all patients come to our Department for sport eligibility evaluation; we have asked them to complete an accurate questionnaire in order to assess their personal physical activity levels and their regular eating habits. Parents were invited to sign a letter explaining the aims of the study and were asked for permission on behalf of their child to take part on the study.

RESULTS

The eating habits and the physical activity levels of the young athletes observed, resulted improper. We have noticed that the 13.7% of the participants were overweight and obese, despite their practiced sport activity. Physical activity, without sport activity, resulted inadequate in 38.6% of participants: they did not practice regular physical activity.

CONCLUSIONS

The results of the study clearly indicate that higher education is therefore necessary in order to promote a healthy lifestyle in terms of both eating habits and physical activity not only in young people, but also in parents and coaches of teams.
