Prevalence and predictors of exclusive breastfeeding among immigrant and Canadian-born Chinese women

Adaptation and psychometric assessment of the postpartum childcare stress checklist among Arab women in the United Arab Emirates

PROBLEM

There is currently no validated version of the Postpartum Childcare Stress Checklist (PCSC) in the context of Arabic-speaking women in the United Arab Emirates (UAE).

BACKGROUND

The postpartum period is a transformative phase in a woman's life, during which mothers are highly vulnerable to mental health problems, compounded by childcare demands. Childcare stress is a strong predictor of postpartum depression. Thus, there is a need for a validated Arabic measure of childcare stress.

AIM

This study aims to translate and psychometrically evaluate the Arabic version of the PCSC among mothers residing in the UAE.

METHODS

The PCSC was psychometrically assessed in a cohort of 399 women in the UAE between February 2017 and September 2018. Using best practices in instrument translation; psychometric evaluation included item-test and item-total correlations, confirmatory factor analysis, tests at two-time points, and validity tests.

RESULTS

The analysis produced a 19-item scale in both unidimensional and multidimensional formats, with Geomin rotated factor loadings ranging from 0.31 to 0.84 and an average variance of 0.46, demonstrating adequate validity. The Arabic PCSC had acceptable reliability coefficients at three (α= = 0.79) and six (α=0.80) months and adequate concurrent and predictive validity at three and six months postpartum.

DISCUSSION

Childcare stress is an internationally reliable and validated construct. The PCSC was also positively correlated with depressive and anxiety symptoms.

CONCLUSION

The Arabic PCSC is a psychometrically validated measure which can be used in future Arabic-language studies and may lead to improved interventions for maternal mental health across Arab-speaking communities.

Exclusive Breastfeeding Rates Among Roma and Non-Roma Mothers in Greece: A Single-Center Cross-Sectional Study from "Tzaneio" General Hospital of Piraeus

BACKGROUND

Exclusive breastfeeding is vital for the optimal development of infants, yet the practice of using infant formula has become increasingly prevalent. While many studies globally investigate factors affecting breastfeeding, there is a scarcity of research focusing on marginalized groups, particularly the Roma community. This study seeks to compare the breastfeeding rates of Roma and non-Roma mothers upon discharge from a maternity hospital in Greece. It also examines factors contributing to the decline in breastfeeding among Roma women, with particular emphasis on the role of midwifery support. The aim of this study is to promote the development of supportive policies and programs for breastfeeding among Roma mothers.

METHODS

A cross-sectional study was conducted from September 2019 to January 2022, involving 248 infants born at ≥37 weeks of gestation and their mothers, who were of Greek nationality. Both Roma and non-Roma participants received consistent, high-quality care from the same midwife researcher, who personally attended to them. All participants initiated breastfeeding immediately after their newborns' births and practiced rooming-in by keeping their babies in the room with them during their hospital stay. Data were collected through questionnaires to determine the rates of exclusive breastfeeding among the two groups.

RESULTS

The study found that a smaller proportion of Roma mothers exclusively breastfed their infants compared to non-Roma mothers, despite receiving similar levels of support from healthcare professionals.

CONCLUSIONS

The provision of midwifery support did not significantly enhance exclusive breastfeeding rates among Roma mothers. This suggests the need for more comprehensive and multi-faceted interventions. Further research is required to confirm these findings and to design effective programs aimed at increasing exclusive breastfeeding rates, thereby improving health outcomes for Roma children and mothers.

Increasing U.S. Maternal Health Equity Among Immigrant Populations Through Community Engagement

Immigrant women in the United States are at an elevated risk of poor maternal health outcomes due to cultural, linguistic, or socioeconomic barriers that may lead to critical delays in obtaining adequate health care. Ensuring access to high-quality, culturally appropriate perinatal health care is crucial to improve the health and well-being of immigrant mothers and their children. Various aspects of perinatal health care for immigrant women can be improved through community engagement strategies. Barriers can be addressed by involving community members in designing and delivering culturally appropriate maternal health services. Some strategies discussed in this commentary include working with community health workers, encouraging telehealth through community health workers, providing breastfeeding and mental health support within cultural norms, and involving community-based doulas and midwives.

Exploring the determinants of exclusive breastfeeding among infants under six months in the Gambia using gambian demographic and health survey data of 2019-20

INTRODUCTION

For infants, no one is as nutritious as breastmilk for the rest of their lives. It is a great guarantee for their future health, especially if they can exclusively breastfeed for the next few months, from the moment they are born until the end of the fifth month. Although breastfeeding rates are very low, there is no data record about it in the Gambia.

OBJECTIVE

This study aimed to assess the status of exclusive breastfeeding and its determinants among infants under six months of age in the Gambia.

METHODS

It is a secondary data analysis using the 2019-20 Gambia demographic and health survey data. A total of 897 weighted mother-infant paired samples were included in the study. A logistic regression analysis method was employed to declare factors significantly associated with exclusive breastfeeding among infants under six months of age in Gambia. Variables with a p-value of 0.2 were entered into multiple logistic regression analysis, and after controlling other confounding factors, an adjusted odds ratio of 95% CI was applied to identify associated variables.

RESULTS

Exclusive breastfeeding was found in 53.63% only among infants under six months of age. Being a rural resident (AOR = 2.14, 95% CI: 1.33, 3.41), reading a newspaper (AOR = 5.62, 95% CI: 1.32, 24.09), and being counseled on breastfeeding by a health professional (AOR = 1.36, 95% CI: 1.01, 1.82) are times more likely to practice exclusive breastfeeding, respectively. On the other hand, a child with a fever (AOR = 0.56, 95% CI: 0.37, 0.84), a child whose age is 2-3 months (AOR = 0.41, 95 CI: 0.28, 0.59), and a child whose age is 4-5 months (AOR = 0.11, 95% CI: 0.07, 0.16) is less likely to be fed exclusively than a 0-1-month-old child.

CONCLUSION

Exclusive breastfeeding remains among the public health challenges in the Gambia. Strengthening health professionals' counseling techniques on breastfeeding and infant illnesses, promoting the pros of breastfeeding, and designing timely policies and interventions are urgently needed in the country.

Breastfeeding in Canada: predictors of initiation, exclusivity, and continuation from the 2017-2018 Canadian Community Health Survey

Human milk is the ideal source of nutrition for infants; however, adherence to breastfeeding recommendations is suboptimal and availability of Canadian breastfeeding data are limited. Using the 2017-2018 Canadian Community Health Survey Public Use Microdata File (Maternal Experiences Module, n = 5558, weighted n = 1 669 462) we computed breastfeeding indicators and explored sociodemographic, health, and geographical predictors of breastfeeding with univariate logistic regression models. Nationally, of all participants who gave birth in the preceding 5 years, 91% initiated breastfeeding, 43% exclusively breastfed to ≥5 months and 35% to ≥6 months, 56% reported any breastfeeding at ≥6 months, and 31% reported breastfeeding at ≥12 months. Breastfeeding cessation was most commonly attributed to insufficient milk supply (25%), but reasons differed significantly by breastfeeding duration. Breastfeeding initiation, exclusivity for ≥5 months, and extended breastfeeding ≥12 months all differed by geographic region, and by most sociodemographic and health characteristics. Positive breastfeeding outcomes were highest in British Columbia, and lowest in Quebec and the Atlantic region, and generally higher if caregivers had recently immigrated to Canada, were married, were >30 years of age, were not White, were nonsmoking, had completed postsecondary education, and had an annual household income >$40 000. These disparities indicate the need for tailored, equitable approaches to breastfeeding support, and continued regional monitoring of breastfeeding outcomes.

Maternal Factors Associated with Non-Exclusive Breastfeeding in Haitian Immigrant Women in Southern Chile

There is limited knowledge concerning factors that affect non-exclusive breastfeeding (NEBF) practices in immigrant populations, especially in Latin America. The objective of the present study was to determine the association between maternal factors and the prevalence of NEBF in Haitian immigrant women in southern Chile. This was an analytical cross-sectional study. The probabilistic sample consisted of 173 Haitian women who gave informed consent. Sociodemographic and dietary-nutritional information was collected from all participants. Bivariate (χ2) and multivariate (logistic regression) inferential statistics were applied. All analyses were performed with the STATA 16.0 statistical software, and the significance level was established as α < 0.05. The prevalence of EBF at 6 mo was 54.3%. Maternal factors associated with a lower prevalence of EBF were not having permanent residency (OR: 2.34, CI: 2.18−2.83), residency <12 months (OR: 2.23, CI: 2.09−2.78), limited knowledge of breastfeeding (OR: 1.96; CI: 1.81−2.27), and low educational attainment (OR: 1.78; CI: 1.61−2.11). The protective factors were employment (OR: 0.36, CI: 0.28−0.40), access to basic services (OR: 0.32; CI: 0.22−0.48), and Spanish proficiency (OR: 0.29; CI: 0.20−0.51). Haitian immigrant women without legal residency, recently arrived, with low educational attainment, and poor knowledge of breastfeeding have more risk of not providing exclusive breastfeeding. Targeted interventions for mothers with these risk factors may help improve EBF rates.

High levels of breastmilk feeding despite a low rate of exclusive breastfeeding for 6 months in a cohort of vulnerable women in Toronto, Canada

Exclusive breastfeeding (EBF) for 6 months is a global public health goal, but measuring its achievement as a marker of population breastmilk feeding practices is insufficient. Additional measures are needed to understand variation in non-EBF practices and inform intervention priorities. We collected infant feeding data prospectively at seven time points to 6 months post-partum from a cohort of vulnerable women (n = 151) registered at two Canada Prenatal Nutrition Program sites in Toronto, Canada. Four categories of breastmilk feeding intensity were defined. Descriptive analyses included the (i) proportion of participants in each feeding category by time point, (ii) use of formula and non-formula supplements to breastmilk, (iii) proportion of participants practising EBF continuously for at least 3 months; and (iv) frequency of transitions between feeding categories. All participants initiated breastmilk feeding with 70% continuing for 6 months. Only 18% practised EBF for 6 months, but 48% did so for at least 3 continuous months. The proportion in the EBF category was highest from 2 to 4 months post-partum. Supplemental formula use was highest in the first 3 months; early introduction of solids and non-formula fluids further compromised EBF at 5 and 6 months post-partum. Most participants (75%) transitioned between categories of breastmilk feeding intensity, with 35% making two or more transitions. Our data show high levels of breastmilk provision despite a low rate of EBF for 6 months. Inclusion of similar analyses in future prospective studies is recommended to provide more nuanced reporting of breastmilk feeding practices and guide intervention designs.

Breastfeeding experiences of Latina migrants living in Spain: a qualitative descriptive study

Background

The migratory flows in Spain have changed due to the arrival of a diverse migrant population. Among the new migrants the Latino collective predominate with more than half being women of childbearing age. There are no previous studies exploring breastfeeding experiences of migrants in a country where their mother tongue is spoken. This study aimed to explore Latina migrants’ breastfeeding experiences in a Spanish-speaking country.

Methods

A descriptive qualitative study was carried out in the main province in southern Andalusia between November 2019 and June 2020. The study used intentional sampling. The study participants were contacted by video calls and data were collected through a semi-structured in-depth interview (n = 19). The interviews were transcribed and analysed by thematic analysis.

Results

The nineteen participants were aged between 22 and 43 years old and came from six different countries in Latin America. The two main categories that emerged were breastfeeding facilitators and barriers, divided into ten interrelated sub-categories: working conditions; precarious socioeconomic conditions; lack of support (health professionals, family and society); physiological changes, pain and fatigue; ignorance and wrong beliefs; support networks (partner, health professionals and family); host country versus home country; religious practices/worship; appropriate attitude, knowledge and experience; and breastfeeding support groups. Most of the study participants stated that their breastfeeding experiences were influenced by barriers such as work and by facilitators such as peer support.

Conclusions

More support from caregivers and more sensitivity to cultural diversity were demanded by the women and well-trained professionals are needed to enable breastfeeding for a longer time. This paper provides caregivers, such as nurses, more knowledge about the care demanded by migrant women to ensure a longer breastfeeding experience.

Navigating Uncertain Times: Information Management about Pregnancy and Breastfeeding during the COVID-19 Pandemic

Pregnant women are especially vulnerable to COVID-19 while the short- and long-term impact of COVID-19 on maternal and infant health is only partially understood. We assessed the amount of uncertainty and anxiety pregnant women experienced about COVID-19 and whether, and the extent to which, they engaged in information seeking about COVID-19. In total, 320 pregnant women from 38 states took part in this research. The results showed that pregnant women experienced uncertainty and anxiety about pregnancy and breastfeeding and engaged in information seeking from their healthcare providers. Pregnant women's uncertainty influenced information seeking via anxiety, but the effect varied depending on participants' assessments of coping, communication, and target efficacy. While healthcare providers need to discuss ways to avoid COVID-19 infection, participants were assured that their providers had a plan to help them if they became infected with COVID-19.

Maternity ward staff perceptions of exclusive breastfeeding in Finnish maternity hospitals: A cross-sectional study

INTRODUCTION

This study aimed to describe exclusive breastfeeding (EBF, Step 6 of the Baby-Friendly Hospital Initiative) in Finnish maternity hospitals and identify factors that promote or limit EBF.

METHODS

A cross-sectional study design was used, and data were collected from eight maternity hospitals in Finland during a 10-day period in May 2014. The staff completed questionnaires (n=1554) from separate work shifts. The data were analyzed using descriptive statistics, and chi-squared and Fisher's tests. Responses to open-ended questions were analyzed using content analysis.

RESULTS

Maternity ward staff reported that 72% (n=1105) of the infants were exclusively breastfed during their work shift. The strongest promoting factors of exclusive breastfeeding were: maternity ward staffs' profession and education in breastfeeding counselling; multiparity; vaginal delivery; early skin-to-skin contact between mother and infant; initial breastfeeding after birth; rooming-in; and initial success of breastfeeding. The use of a nipple shield, the need for additional breastfeeding counselling, and infants' blood tests were limiting factors to exclusive breastfeeding. Open-ended answers revealed that exclusive breastfeeding was mainly delayed because of medical issues for the mother or infant.

CONCLUSIONS

Finnish maternity hospitals could improve exclusive breastfeeding rates by focusing attention and resources on breastfeeding counselling and evidence-based maternity care practices related to immediate care after birth, promoting vaginal delivery, rooming-in and availability of skilled counselling.

Breastfeeding but not Exclusively: Exploration of Chinese American Mothers' Infant Feeding Practices

BACKGROUND

Previous qualitative researchers have shown that Chinese American mothers experienced high rates of suboptimal breastfeeding, especially early introduction of other foods before the recommended 6-month period of exclusive breastfeeding.

RESEARCH AIMS

(1) To explore attitudes that Chinese American mothers have about the meaning and practice of exclusive breastfeeding; (2) to evaluate the extent of family pressure and support to maintain exclusive breastfeeding; and (3) to examine the influence of breastfeeding self-efficacy and the intention to continue exclusive breastfeeding.

METHOD

Guided by the theory of planned behavior, this descriptive cross-sectional prospective online survey was conducted with Chinese American breastfeeding mothers (N = 401). Participants' attitudes, subjective norms, and perceived behavioral control for exclusive breastfeeding behaviors were measured.

RESULTS

The M (SD) age of participants was 29.14 (SD = 6.90). Just over 50% reported receiving family support for exclusive breastfeeding. While participants had positive attitudes about exclusive breastfeeding and the value of colostrum, 64% (n = 257) had already introduced foods other than mother's own milk before their infant was 6-months old. Participants also expressed concern that their infants did not receive enough nutrition from exclusive mother's milk. Participants with more than one child had significantly greater intention to continue exclusive breastfeeding compared to participants with only one child. Perception of approval by others for exclusive breastfeeding and breastfeeding self-efficacy were significantly related to behavioral intention to continue exclusive breastfeeding.

CONCLUSION

Suboptimal infant feeding is a problem for Chinese American women and may also be a problem for mothers in other ethnic groups. We found a lack of adherence with standard recommendations for sustaining 6-months of exclusive breastfeeding.

Barriers for early initiation and exclusive breastfeeding up to six months in predominantly rural Sri Lanka: a need to strengthen policy implementation

Background

Sri Lanka was named as the first-ever ‘Green’ breastfeeding nation status by the World Breastfeeding Trends Initiative (WBTi) in January 2020. However, improvements are still needed. This study aims to identify barriers and facilitators for early initiation of breastfeeding and exclusive breastfeeding for 6 months in rural Sri Lanka.

Methods

We conducted in-depth interviews with 16 mothers with infants, who had been unable to practice early initiation of breastfeeding and/or exclusive breastfeeding (EBF), in six child-welfare clinics in Anuradhapura, Sri Lanka. Three focus group discussions were held with public health midwives (PHMs). Initial thematic analysis that built upon force field and social learning theories was performed.

Results

Main barriers for EBF were clustered at three time periods; during the first 2–3 days, 2–3 weeks, and 4–5 months postpartum. Early barriers included cesarean section pain, poor breast latch, maternal exhaustion, suboptimal maternity ward environment, and lack of support for breastfeeding. Around 2–3 weeks postpartum mothers introduced water or infant formula due to social norms and poor support. On-demand feeding was misunderstood. Around 4 and 5 months postpartum, EBF ended due to return to work. PHMs reported a heavy workload limiting their time to support breastfeeding.

Conclusion

EBF interruption was due to diverse individual- and environnmental- level barriers that varied across the first 6 months. To improve EBF, Sri Lanka should focus on strengthening policies for reducing the excessive rates of cesarean section, improving support in maternity ward facilities, fostering on-demand breastfeeding, enhancing support for working mothers and reducing the work load of PHMs.

Patterns and predictors of exclusive breastfeeding in Chinese Australian mothers: a cross sectional study

BACKGROUND

While exclusive breastfeeding is recommended to 6 months of age, just 15% of mothers in Australia achieve this. The rate appears to be even lower among mothers born in China, where 90% have introduced infant formula by this time. This study aimed to examine infant feeding patterns in the first 12 months of life and the factors associated with exclusive breastfeeding at 4 months of age and infant formula introduction by 1 month of age among Chinese Australian mothers.

METHODS

Chinese Australian women with a child aged 1 to 4 years born in Australia were recruited through social media and asked to complete an online survey. Chinese ethnicity was defined as the mother or her parents having been born in mainland China, Taiwan or Hong Kong. Infant feeding practices since birth and a range of psychosocial and cultural factors were assessed. A total of 289 Chinese Australian mothers completed the survey. The relationships between exposure variables and exclusive breastfeeding at 4 months or infant formula use by 1 month were examined using multivariable logistic regression.

RESULTS

Almost all (93%) mothers initiated breastfeeding, however by 1 month of age exclusive breastfeeding rates reduced to 44%, with a further decline to 33 and 18% at 4 and 6 months respectively. Concurrently, 7% of parents reported infant formula feeding at birth increasing to 55 and 63% at 1 and 6 months of age respectively. The rates of any breastfeeding were 81% at 6 months and 50% at 12 months of age. Breastfeeding intention, self-efficacy and awareness of the infant feeding guidelines were key factors associated with sustained exclusive breastfeeding to 4 months.

CONCLUSIONS

While Chinese Australian mothers had comparable exclusive breastfeeding rates at 6 months to the general Australian population, twice as many had introduced infant formula by 1 month of age. There is an urgent need to support Chinese Australian mothers in the perinatal period to strengthen their knowledge, intention and confidence to delay early introduction of infant formula and promote exclusive breastfeeding in the early postpartum period.

Promoting Sustained and Exclusive Breastfeeding among Chinese American Pregnant Women

This study investigated prenatal goal setting and breastfeeding attitudes and intentions for 210 Chinese American pregnant women. In addition, this study assessed impact of person-centered versus factual messages on breastfeeding attitudes and intentions. While pregnant women reported receiving information about Baby-Friendly designated hospitals from healthcare providers, most received no breastfeeding information from those same providers. Although women had positive attitudes toward breastfeeding, they showed lack of knowledge about colostrum, general approval for using infant formula, as well as early introduction of complementary foods. By extension, these attitudes suggested they misunderstood the meaning of exclusive breastfeeding. No differences were observed based on parity, trimester of pregnancy, level of education or income. Person-centered and factual messages were judged as equally effective messages, but intention to breastfeed was more affected by the factual message. Reasons for this result are discussed. Healthcare providers are positioned to proactively engage in maternal preparedness for exclusive breastfeeding. These results suggested a missed opportunity for healthcare providers to communicate the value of sustained exclusive breastfeeding for the recommended first 6 months of an infant's life and underscore a need for all antenatal healthcare providers to collaboratively ensure that breastfeeding information is comprehensively provided throughout the span of antenatal care.

Exposure to baby-friendly hospital practices and mothers' achievement of their planned duration of breastfeeding

BACKGROUND

Both breastfeeding intentions and exposure to baby-friendly hospital practices were found to be associated with a longer duration of breastfeeding. This study aims to examine the effect of exposure to baby-friendly hospital practices on mothers' achievement of their planned duration of breastfeeding.

METHODS

A total of 1011 mother-newborn pairs from the postnatal units of four public hospitals in Hong Kong were recruited. Sociodemographic data and breastfeeding intention data were collected via self-report questionnaires during the postnatal hospitalization and exposure to Baby-Friendly hospital practices were assessed through hospital records and maternal self-report. Breastfeeding status after hospital discharge was assessed through telephone follow-up for up to 12 months postnatal, or until participants were no longer breastfeeding.

RESULTS

Only 55% (n = 552) of study participants achieved their intended duration of breastfeeding. Participants with higher socioeconomic status, previous breastfeeding experience, and those who had lived in Hong Kong for less than 5 years, were more likely to achieve their planned duration of breastfeeding. Among baby-friendly hospital practices, feeding only breast milk during the hospitalization and providing information about breastfeeding support on discharge were associated with participants' achieving their individual breastfeeding intentions. After adjustment, when compared with women who experienced onebaby-friendly practice, participants who experienced six baby-friendly hospital practices were significantly more likely to achieve their planned duration of breastfeeding (adjusted odds ratio = 8.45, 95% confidence interval 3.03-23.6).

CONCLUSIONS

Nearly half of participants did not achieve their planned breastfeeding duration. Exposure to baby-friendly hospital practices, especially in-hospital exclusive breastfeeding and providing breastfeeding support information upon hospital discharge may help more mothers to achieve their individual breastfeeding goals.

Trajectory and Predictors of Fatigue Among Chinese Immigrant and Chinese Canadian-Born Women in the Postpartum Period

OBJECTIVE

To describe the proportion of women with improving or worsening symptoms of fatigue at 1, 3, 6, and 12 months after birth; to model the trajectory of fatigue across the first year after birth and identify baseline predictors (e.g., immigrant status) and time-varying predictors; and to describe the degree to which fatigue interferes with activities of daily living across the first year after birth among a cohort of Chinese immigrant and Chinese Canadian-born women.

DESIGN

Prospective cohort study.

SETTING

Toronto, Ontario, Canada.

PARTICIPANTS

Chinese women who were recent immigrants (n = 244), nonrecent immigrants (n = 247), or Canadian born (n = 100).

METHODS

Women completed surveys at 1, 3, 6, and 12 months after birth. We measured fatigue with the use of the Multidimensional Assessment of Fatigue scale. Fatigue predictor variables were classified as baseline (e.g., immigrant status) or time varying (e.g., depression). We used latent growth curve modeling to examine fatigue trajectories and identify predictors over time.

RESULTS

Fatigue followed a nonlinear pattern: it improved from 1 to 6 months after birth and then worsened from 6 to 12 months after birth. Depression, anxiety, infant sleep characteristics, and breastfeeding problems, but not immigrant status, significantly increased risk for fatigue. Several daily activities were significantly influenced by fatigue, particularly early in the postpartum period as well as later, which showed a U-shaped relationship between fatigue and activities of daily living.

CONCLUSION

Fatigue is common and persistent across the postpartum period. Modifiable risk factors related to mental health, infant sleep, and breastfeeding difficulties suggest that preventive strategies for maternal fatigue warrant further investigation.

Changing epidemiology of immune-mediated inflammatory diseases in immigrants: A systematic review of population-based studies

BACKGROUND

Immune-mediated inflammatory diseases (IMIDs) are systemic diseases of multifactorial etiology that share aberrant immune responses as the common final pathway. With rising globalization, their incidence is increasing in developing countries and among immigrants. Our primary objective was to systematically review the epidemiology of IMIDs in immigrants and conduct a meta-analysis to estimate the risk of IMIDs in immigrant populations according to their origin and destination countries.

METHODS

We systematically searched five biomedical databases and reviewed population-based studies, from inception through August 2018, that reported incidence or prevalence data of inflammatory bowel disease (IBD), multiple sclerosis (MS), type 1 diabetes (T1D), systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), ankylosing spondylitis (AS) or psoriasis and psoriatic arthritis (PPA) among immigrants and the host population.

RESULTS

The incidence and prevalence of IMIDs among immigrants differ from host populations, and evolve over subsequent generations. The risk of IBD among immigrants approximates that in hosts, especially among South Asians, with ulcerative colitis incidence changing prior to Crohn's disease incidence. MS risk is highest in Iranian immigrants, T1D in African immigrants and SLE in African and Iraqi immigrants. Data on other IMIDs are sparse. Significant heterogeneity between the studies precluded meta-analysis.

CONCLUSION

Based on our systematic review, the epidemiology of IMIDs among immigrants varies according to native and host countries, immigrant generation, and IMID type. The rapid evolution suggests a role for non-genetic factors and gene-environment interactions. Future studies should focus on these pattern shifts, given implications of rising global burden of IMIDs and immigration.

Prevalence and predictors of exclusive breastfeeding among immigrant and Canadian-born Chinese women

Breastfeeding is the optimal method for infant feeding, yet migrant women may be at risk for suboptimal exclusivity rates. In a cohort of immigrant and Canadian-born Chinese women, our objectives were to (a) describe patterns and prevalence of exclusive breastfeeding at 1, 3, and 6 months postpartum; (b) identify risk and protective factors associated with exclusivity; and (c) examine potentially differential importance of these factors across this 6-month period. This was a prospective study of 565 immigrants and Canadian-born Chinese women (Toronto, Canada). Exclusive breastfeeding was measured at 1, 3, and 6 months postpartum. Predictors comprised fixed (demographics, history of depression, immigrant status, prenatal breastfeeding classes, in-hospital formula supplementation, baseline social support, and baseline acculturative stress) and time-dependent (depression, anxiety, fatigue, and breastfeeding problems) variables. Descriptive statistics, logistic regression, and generalized linear mixed models, respectively, were undertaken to address the objectives. Patterns of breastfeeding practices included exclusive breastfeeding in all time points (26.8%) or none (32.9%) and moving from exclusive to nonexclusive (20.3%) or nonexclusive to exclusive breastfeeding (15.2%). Women less likely to breastfeed exclusively at 1, 3, or 6 months were those whose infants received in-hospital formula supplementation. Exclusivity attrition was higher between 3 and 6 months than 1-3 months. Immigrant status and in-hospital formula supplementation had a significant impact on exclusivity earlier in the postpartum period while breastfeeding problems were associated with decreased exclusivity across time. Proactive preventive efforts are need to maintain breastfeeding exclusivity especially between 3 and 6 months if women are to meet international breastfeeding recommendations.
