RESUMO
PROBLEM: Current versions of Canada's Food Guide (CFG) aim to inform a culturally diverse population, but it is not known how intended audiences from different cultural and linguistic groups within Canada's diverse population understand and apply its messages. METHODS: We analyzed data from qualitative interviews conducted with 32 newcomer mothers of children aged 1-5 years to explore how conceptions of food and health change with migration to Canada among Spanish-speaking Latin American and Tamil Speaking Sri Lankan newcomers and may influence the appropriateness and applicability of Canada's Food Guide (CFG) as a nutrition education tool. We applied Jordan's model of authoritative knowledge to identify different forms of newcomer maternal nutrition knowledge, how they influence child feeding practices, and shifts causing some forms of knowledge to be devalued in favor of others. RESULTS: Awareness of CFG differed between groups, with all Latin American and only half of Tamil participants familiar with it. Three distinct, overlapping ways of knowing about the relationship between food and health are identified within both groups of mothers: "natural" foods as healthy; influence of foods on illness susceptibility, and the nutritional components of food. CFG was found to be limited in its representations of recommended foods and its exclusive utilization of biomedical concepts of nutrition. CONCLUSIONS: Development of new, culturally competent versions of CFG that depict a variety of ethno-culturally meaningful diets and encompass both non-biomedical conceptualizations of food and health has the potential to enhance effective knowledge translation of CFG's key messages to an increasingly cosmopolitan Canadian population.

BACKGROUND: Despite elevated risk profiles for depression among South Asian and Black Caribbean people in the UK, prevalences of late-life depressive symptoms across the UK's three major ethnic groups have not been well characterized. METHOD: Data were collected at baseline and 20-year follow-up from 632 European, 476 South Asian and 181 Black Caribbean men and women (aged 58-88 years), of a community-based cohort study from north-west London. The 10-item Geriatric Depression Scale was interviewer-administered during a clinic visit (depressive symptoms defined as a score of ⩾4 out of 10), with clinical data (adiposity, diabetes, cardiovascular disease, cognitive function) also collected. Sociodemographic, psychosocial, behavioural, disability, and medical history information was obtained by questionnaire. RESULTS: Prevalence of depressive symptoms varied by ethnic group, affecting 9.7% of White European, 15.5% of South Asian, and 17.7% of Black Caribbean participants. Compared with White Europeans, South Asian and Black Caribbean participants were significantly more likely to have depressive symptoms (odds ratio 1.79, 95% confidence interval 1.24-2.58 and 1.80, 1.11-2.92, respectively). Adjustment for co-morbidities had most effect on the excess South Asian odds, and adjustment for socioeconomic position had most effect on the elevated Black Caribbean odds. CONCLUSIONS: Higher prevalence of depressive symptoms observed among South Asian people were attenuated after adjustment for physical health, whereas the Black Caribbean increased prevalence was most explained by socioeconomic disadvantage. It is important to understand the reasons for these ethnic differences to identify opportunities for interventions to address inequalities.

This study aimed to compare objectively recorded physical activity (PA) levels and walking steps among pregnant women. Cross-sectional data from a multiethnic cohort (n = 823) of pregnant women consisting of 44% from Western countries, 24% from South Asia, 14% from Middle East, and 18% from other countries. PA and steps were recorded by the activity monitor SenseWear™ Pro3 Armband. A total of 678 women were included in the analysis. Western women walked significantly more steps and had higher moderate-to-vigorous-intensity physical activity (MVPA) levels compared with South Asian women per weekday and weekend day. Interaction terms (P = 0.008) between ethnicity (Western vs South Asian) and parity, and education, respectively, were identified: having ≥ 1 children was positively associated with steps during weekends in South Asians in contrast to Western women. Having <12 years education was associated with more MVPA time among South Asians in contrast to Western women. South Asian women are prone to low levels of PA during pregnancy and South Asian women without children and with higher education may have an elevated risk for an inactive lifestyle during pregnancy.

Cephalic index is an important parameter in evaluating racial and gender differences. A large body of evidence shows a clear racial variation in cephalic index. Therefore detailed knowledge of the population specific data on biometric features of the cranium is important in the study and comparison of the crania of populations from different racial backgrounds, assessing growth and development of an individual and in the diagnosis of any abnormalities of cranial size and shape. Despite its' significance, little is known concerning the cranial morphometry in Sri Lankans. Hence, the present study was undertaken to establish the cranial indices and head shapes in an adult Sri Lankan population. A total of 400 subjects with an age span of 20-23 years were included in the study. The cranial length, breadth and auricular head height of the subjects were recorded using a digital sliding caliper and Todd's head spanner. The horizontal, vertical and transverse cephalic indices were calculated using external dimensions of the skulls. There were significant gender differences in all principal cranial dimensions. The mean horizontal, vertical and transverse cephalic indices were 78.54, 78.68 and 100.52 respectively. The predominant cephalic phenotype of the study subjects were brachycephalic, hypsicephalic and acrocephalic. Among males dolicocephalics and among females brachycephalics dominated. The results of this study highlight the racial and gender differences in cranial morphometry and cephalic indices in an adult Sri Lankan population. The data will be of immense use in clinical, medico-legal, anthropological and archeological scenarios.
El índice cefálico es un parámetro importante para evaluar las diferencias raciales y sexuales. Una gran cantidad de evidencia muestra una clara variación racial en el índice cefálico. Por tanto, un conocimiento detallado de los datos específicos de una población sobre las características biométricas del cráneo, son importantes en el estudio y la comparación craneal de poblaciones de diferentes orígenes raciales, evaluación del crecimiento y desarrollo de un individuo, y el diagnóstico de cualquier anomalía del tamaño o forma del cráneo. A pesar de su importancia, poco se conoce sobre la morfometría craneal en Sri Lanka. El presente estudio se realizó para establecer los índices cefálicos y formas de la cabeza en una población adulta de Sri Lanka. Un total de 400 sujetos entre 20 y 23 años fueron incluidos en el estudio. La longitud de la cabeza, ancho y altura auricular fueron registradas con un caliper digital deslizante y un aparato de Todd. Los índices cefálicos horizontales, verticales y transversales fueron calculados utilizando las dimensiones externas de los cráneos. Hubo diferencias significativas de sexo en todas las dimensiones de la cabeza. La media horizontal, vertical y transversal de los índices cefálicos fueron 78,54; 78,68 y 100,52, respectivamente. Los fenotipos cefálicos predominantes fueron braquicéfalos, hipsicefálicos y acrocéfalos. Entre los hombres dominaron los dolicocefalos y entre mujeres los braquicéfalos. Los resultados de este estudio ponen de relieve la diversidad racial y las diferencias de sexo en la morfometría craneal e índice cefálico en una población adulta de Sri Lanka. La información será de utilidad inmensa en clínica, medicina legal, escenarios antropológicos y arqueológicos.

BACKGROUND: To estimate the risk of hyperemesis gravidarum (HG) among first generation immigrants to Norway by length of residence. DESIGN: A cross-sectional study. METHODS: The sample consisted of first generation immigrants with a prevalence of HG exceeding ethnic Norwegians by 50%, registered in the Medical Birth Registry of Norway (MBRN). The women were born in Turkey, Middle East, North Africa, Other Africa, Iran, Pakistan, India and Sri Lanka and Central and South America, the total sample size is 50,904. MBRN data on HG, age, parity, plurality and sex of the baby were linked to information on country of birth, maternal education and duration of stay obtained from Statistics Norway. Independent associations were studied for each immigrant group and adjusted for potential confounders. To account for dependencies in the sample, a generalized estimating equations (GEE) approach was used. RESULTS: For women from Central and South America, adjusted analysis showed a decrease in the risk of HG by longer residency (P for trend = 0.026). A similar but not significant trend was observed for women born in the Middle East (P for trend = 0.097). Women born in Turkey who had been living in Norway for 6-8 years had a higher risk of HG than newcomers, though no trend was observed (P for trend = 0.127). Women born in Iran and North Africa who lived longer in Norway tended to have a higher risk of developing HG than newcomers (P for trend = 0.083 and 0.118, respectively) CONCLUSION: Associations between HG and duration of residence in Norway did not show a universal pattern across immigrant groups. Women born in Central and South America had a lower risk of HG with increasing length of residence. Some evidence to the contrary was found for women born in Iran, North Africa and Turkey.

BACKGROUND: Size and body proportions at birth are partly determined by maternal body composition, but most studies of mother-baby relationships have only considered the effects of maternal height and weight on offspring birth weight, and few have examined the size of effects. Paternal size and body composition also play a role, primarily through the fetal genome, although few studies have investigated relationships with neonatal phenotype. METHODS: Data from the UK, Finland, India, Sri Lanka, China, DR Congo, Nigeria and Jamaica were used to investigate the effects of maternal measures (derived at 30 weeks' gestation, n=16,418), and also paternal size (n=3,733) on neonatal phenotype, for singleton, live-born, term births. RESULTS: After accounting for variation in maternal size and shape across populations, differences in neonatal phenotype were markedly reduced. Mother-baby relationships were similar across populations, although some were stronger in developing countries. Maternal height was generally the strongest predictor of neonatal length, maternal head circumference of neonatal head and maternal skinfold thickness of neonatal skinfolds. Relationships with maternal arm muscle area were generally weak. Effects of paternal height and body mass index were weaker than the equivalent maternal measurements in most studies. CONCLUSIONS: Differences in maternal body composition account for a large part of the geographical variation in neonatal phenotype. The size of the effects of all maternal measures on neonatal phenotype suggests that nutrition at every stage of the mother's life cycle may influence fetal growth. Further research is needed into father-baby relationships and the genetic mechanisms that influence fetal growth.

BACKGROUND: Recent studies have shown associations between size and body proportions at birth and health outcomes throughout the life cycle, but there are few data on how neonatal phenotype varies in different populations around the world. METHODS: Data from the UK, Finland, India, Sri Lanka, China, DR Congo, Nigeria, and Jamaica (n=22,067) were used to characterize geographical differences in phenotype in singleton, live-born newborns. Measurements included birth weight, placental weight, length, head, chest, abdominal and arm circumferences, and skinfolds. RESULTS: Neonates in Europe were the largest, followed by Jamaica, East Asia (China), then Africa and South Asia. Birth weight varied widely (mean values 2,730-3,570 g), but in contrast, head circumference was similar in all except China (markedly smaller). The main difference in body proportions between populations was the head to length ratio, with small heads relative to length in China and large heads relative to length in South Asia and Africa. CONCLUSIONS: These marked geographical differences in neonatal phenotype need to be considered when investigating determinants of fetal growth, and optimal phenotype for short-term and long-term outcomes.

In a longitudinal study, internationally adopted children (N = 146) placed before 6 months of age were followed from infancy to age 7. Results showed that girls were better adjusted than boys, except in cognitive development, and that easy temperament was associated with higher levels of social, cognitive, and personality development and fewer behavior problems. Higher quality of child-mother relationships, in terms of attachment security and maternal sensitivity, uniquely predicted better social and cognitive development. The combination of attachment disorganization and difficult temperament predicted less optimal ego-control and lower levels of cognitive development. It is concluded that even in adopted children, who are not biologically related to their adoptive parents, early mother-infant interactions and attachment relationships predict later socioemotional and cognitive development, beyond infant temperament and gender.

The present study (N = 159) provides evidence of an increased risk for behavior problems of infant-placed 7-year-old internationally, transracially adopted children in the Netherlands. However, parents reported more behavior problems for adopted boys than for adopted girls. Notably, about 30% of the adopted children were classified as clinical on the CBCL scale for total problems, which is a much larger percentage than the 10% found in the normative population. It was suggested that these results could be explained by the operation of multiple risk factors before and after adoption placement, e.g. the child's genetic disposition, pre-natal and pre-adoption care, or the child's cognitive understanding of adoption in middle childhood. Also, results suggest that maternal sensitive responsiveness in adoptive families declines in the transition from early to middle childhood. In contrast to the home setting, the adopted children showed favorable behavioral and socioemotional adjustment at school, while their academic achievement and intelligence were in the normal range or above average. In particular Korean children had high IQs: 31% of these children obtained an intelligence score above 120. It was suggested that adoptive parents seem to offer their children sufficient or even more than average cognitive stimulation. Furthermore, adopted girls scored higher in optimal ego-control, social competence, and peer group popularity than nonadopted girls from the general population: 30% of the adopted girls were rated as popular by their classmates, which compares favorably to the 13% found in the general school population.

OBJECTIVES: To examine suicide rates and trends in people of Indian subcontinent, east African and Caribbean origin using the latest mortality data available for England and Wales. To compare suicide rates in these groups with the baseline and target rates for suicide in the Health of the Nation strategy. METHODS: Suicide data for England and Wales for 1988-1992, classified by the country of birth of the deceased, and population denominators from the 1991 Census were used for the analysis. Standardised mortality ratios (SMRs) for ages 15-64 and age-specific ratios were computed, using the age-sex specific rates for England and Wales as the standard. Trends over the preceding decade and suicide by burning were also analysed. Directly age-standardised suicide rates were derived to facilitate comparison with Health of the Nation baseline and target rates. RESULTS: Suicide ratios were significantly low (SMRs 32, 52 and 55 respectively) in Bangladeshi, Sri Lankan and Pakistani born men at all ages, but raised in young Indian and east African men. Ratios were significantly high in Indian and east African women (143 and 154), with a 2-3 fold excess at ages 15-34 years. Ratios were low in Pakistani and Bangladeshi women overall, but elevated at 15-24 years. For the Caribbean-born, ratios were low overall but raised at ages 25-34. 20% of Asian female suicides were by burning. Indians are a high risk group in terms of the Health of the Nation suicide targets. Suicide trends in the minority ethnic groups reflect national trends. CONCLUSIONS: This study confirms previous findings of high suicide rates in young Asian women. A new finding is the raised suicide rate in young Caribbeans. High suicide risks among young people from some ethnic minority communities are significant in the context of both the Health of the Nation strategy and recent governmental concern about the need to tackle health variations in the UK. Such deaths are indicative of larger numbers of young ethnic minority adults at risk of mental distress and self harm.
