Gender differences in acculturation and cardiovascular disease risk-factor changes among Chinese immigrants in Italy: Evidence from a large population-based cohort

Effects of length of residency on the development of physical and mental illnesses in immigrant women in Taiwan: a retrospective cohort study using nationwide data

OBJECTIVES

The majority of female immigrants who are married in Taiwan often face a variety of stresses, which may lead to physical or mental illness. Yet few studies have validated the impact of length of residency on physical and mental health using large-scale data. This study combined five nationwide databases and explored the impact of length of residency in Taiwan on the physical and mental health of female marriage immigrants.

DESIGN

This is a retrospective cohort study.

SETTING

Taiwan.

PARTICIPANTS

A total of 168 202 female immigrants, who were registered in the national health insurance database from 2001 to 2017, were enrolled for analysis.

MEASURE

The length of residency was taken as the period from their first appearance in the national health insurance database to the end of 2017. Hypertension and diabetes were chosen as indices of physical health and depression as an index of mental health. Diagnosis standards were based on the International Classification of Disease, ninth or 10th Revision.

RESULTS

The physical and mental health of the immigrants deteriorated with increasing time of residence in Taiwan. Immigrants who had resided in Taiwan for 5-10 years or ≥10 years, respectively, had a 5.8-fold (95% CI: 3.46 to 9.74) or 6.29-fold (95% CI: 4.61 to 8.59) higher adjusted risk of developing hypertension; a 3.97-fold (95% CI: 2.54 to 6.21) or 9.18-fold (95% CI: 5.48 to 15.38) higher adjusted risk of developing diabetes; and a 5.01-fold (95% CI: 3.14 to 8.01) or 12.19-fold (95% CI: 8.65 to 17.18) higher adjusted risk of developing depression than their counterparts who had lived in Taiwan for ≤5 years.

CONCLUSION

These findings suggest the time elapsed since migration can be a factor in the deterioration of both physical and mental health among female marriage immigrants in Taiwan.

Impact of migration on diabetes burden: audit in the metropolitan area of Bologna, Italy

PURPOSE

To investigate the impact of diabetes in immigrants on the Italian healthcare system, as well as their compliance with standard protocols of control and treatment.

METHODS

The prevalence of immigrants with diabetes living in the metropolitan area of Bologna (about 1 million inhabitants) in 2019 was investigated using a database containing all subjects in active follow-up for diabetes, based on antidiabetic drug use, disease-specific copayment exemption, ICD-9 codes, continuous care in diabetes units. Country of origin was derived from fiscal code.

RESULTS

The overall prevalence of diabetes (n = 53,941; 51.8% males, median age 64) was 6.1% in both Italy-born and immigrant cohorts. Immigrant prevalence was 12.4%, moderately higher than that observed in the total population (12.2%). Diabetes risk was increased in the whole immigrant cohort (odds ratio (OR) 1.74; 95% Confidence Interval (CI) 1.69-1.79). Among cases with incident diabetes, the proportion of immigrants (median age, 49 vs. 65 in Italy-born individuals) increased progressively from 11.7% to 26.5% from 2011 to 2019 (males, 8.9-21.0%; females, 14.9-32.8%) in all age groups, particularly in young adults, but also in older subjects. Metabolic control was lower in immigrants, as was adherence to shared diagnostic and therapeutic protocols, without systematic differences in antidiabetic drug use, but much lower use of drugs for comorbid conditions.

CONCLUSIONS

The population with diabetes in the metropolitan area of Bologna is rapidly changing. Quality improvement initiatives are needed to reduce the burden for the universalistic Italian health care system generated by the rapidly-growing high-risk immigrant population.

Protocol for the CHINT study: a cross-sectional observational study of risk factors for cancer and other non-communicable diseases in the Chinese community of Milan

INTRODUCTION

The Chinese community in Italy is the largest in Europe. The area of Milan hosts the largest Chinese Italian community-about 41 000 people. Since little is known of the health practices of Chinese persons in Italy, we designed the CHINT study (survey of risk factors for cancer and other non-communicable diseases (NCDs) in the Chinese community of Milan) to investigate lifestyle-related risk factors for these diseases in this community. We expect the study to reveal potentially unhealthy lifestyle behaviours that may be addressed in future prevention programmes.

METHODS AND ANALYSIS

The CHINT study is a cross-sectional study on a sample of around 600 adults recruited from the Chinese community of Milan and surrounding areas. The non-random sample is clustered by age, sex, occupation and socioeconomic characteristics and is being recruited with the active cooperation of stakeholders within the Chinese community. The study employs face-to-face meetings, text messaging and WeChat. At the first recruitment meeting, participants' physical measurements are taken and a lifestyle questionnaire is administered which enquires about physical activity, the consumption of salt, fruit and vegetables, tobacco and alcohol, and the presence of other risk factors for NCDs. A food frequency questionnaire is in preparation. By analysis of physical data and the results of the two questionnaires, the prevalence and distribution of NCD risk factors, and characteristics associated with these factors, will be identified. Factors associated with recruitment and compliance/retention will be investigated to identify predictors of willingness to participate future intervention studies.

ETHICS AND DISSEMINATION

The study has been approved by the ethics committee of the Fondazione IRCCS Istituto Nazionale dei Tumori di Milano, Italy. All participants are required to provide written informed consent. Findings will be disseminated through peer-reviewed scientific publications, conferences and public meetings involving the Chinese community and the lay public.

Migrating Populations and Health: Risk Factors for Cardiovascular Disease and Metabolic Syndrome

PURPOSE OF REVIEW

To summarize results of recent studies of migrants in Europe and North America and ongoing efforts to adapt strategies to provide them with inclusive sensitive health care.

RECENT FINDINGS

Major predisposing factors for developing hypertension, obesity, diabetes, and the metabolic syndrome in migrating populations and refugees were identified. Susceptibility to the metabolic syndrome is predominantly due to environmental factors and psychological stress. Acculturation also contributes to the emergence of cardiovascular (CV) risk factors in first-generation adult immigrants. Increased risk for later development of hypertension and dyslipidemia has also been detected in adolescent immigrants. Targets for public health efforts were based on data that show important differences in CV risk factors and prevalence of the metabolic syndrome among ethnic immigrant groups. Studies in young adults focused on lifestyle and dietary behaviors and perceptions about weight and body image, while the focus for older adults was end-of-life issues. Two important themes have emerged: barriers to health care, with a focus on cultural and language barriers, and violence and its impact on immigrants' mental health.

Body-Size Perception among First-Generation Chinese Migrants in Italy

Body-size perception is an important factor in motivating people to lose weight. Study aim was to explore the perception of body image among first-generation Chinese migrants living in Italy. A sample of 1258 Chinese first-generation immigrants and of 285 native Italians living in Prato, Italy, underwent blood pressure measurements, blood tests (with measurement of glucose, cholesterol, and triglycerides), and anthropometric measurements. Body-size perception was investigated with Pulvers’ figure rating scale using logistic or linear multivariable regression adjusted for age, gender, BMI, education and years spent in Italy. Chinese migrants had lower BMI and discrepancy score (preferred minus current body size) than Italians (p < 0.05 for both). After a logistic regression analysis, the discrepancy score remained lower in the Chinese than in the Italian cohort independently from BMI and other confounders (OR 0.68; 95%CI 0.50 to 0.92). In the Chinese cohort, female gender, BMI and years spent in Italy were positive determinants of discrepancy score (desire to be thinner), while age showed negative impact (p < 0.05 for all). Overweight is an important risk factor for diabetes, a very prevalent condition among first-generation Chinese migrants. The present study offers useful information and suggests the need for prevention programs specifically addressed to men.
