Migration and gout: the Tokelau Island migrant study.

The prevalence and 14 year incidence of clinical gout and its precursors were investigated in the Polynesian population of Tokelauans living in the Pacific basin, non-migrant Tokelauans living in their isolated atoll homeland being compared with migrant Tokelauans living in urban New Zealand. The age standardised prevalence of gout in Tokelauan men in New Zealand was higher than that in non-migrant Tokelauan men, being 21.0 and 19.5/1000 subjects at the beginning of the study and 51.0 and 14.6/1000 at the end of study, respectively. Migrant men in New Zealand aged under 55 had higher mean serum uric acid concentrations than non-migrant men of the same age. The prevalence of gout was low in women in both environments. The age standardised relative risk of developing gout between 1968 and 1982 was 9.0 times higher in the migrant men than in the non-migrant men. Age, serum uric acid concentration, serum cholesterol concentration, and self reported alcohol consumption at entry to the study were the best set of predictors of gout in men. Preventive strategies to change body mass, diet, and patterns of alcohol use need to be developed in this population.

Cancer incidence in Estonian migrants to Sweden.

Cancer incidence in Estonians who took refuge in Sweden in 1944-1945 has been compared with that in the total Swedish population and that among Estonians in Estonia in 1974-1985 using data from the Swedish and the Estonian countrywide population-based cancer registries. The vast majority of the Estonian immigrants studied had been living in Sweden for 30 years when the follow-up with respect to cancer incidence started in this investigation. In spite of the long residence in Sweden, differences in cancer incidence could be observed between these immigrants and the total Swedish population. The age-standardized incidence of stomach cancer was higher in the Estonian migrants than in the total Swedish population (SIR = 1.6 and 2.1 for males and females, respectively). Breast cancer incidence was lower in the migrant women (SIR = 0.75) and lung cancer incidence higher in migrant men (SIR = 1.5). An increased incidence of colorectal cancer was also found for both sexes in the migrant population (SIR = 1.4 for both males and females). A comparison between Estonians in Estonia and the total Swedish population revealed that the cancer incidence for the Estonians was lower than expected at age 70 and over. Male lung cancer and stomach cancer showed a higher incidence in the Estonian population than in the Swedish and in the migrant populations. The migrant population showed an intermediate incidence relative to Estonians in Estonia and the entire Swedish population. The colon-cancer risk in Estonian migrants to Sweden was higher than the risk for Estonians in Estonia and for the Swedish population. This contrasts with most findings in the present and other studies on intermediate risks of migrants compared to the risks in the country of origin and in the new country of residence.

Rheumatic complaints in Tokelau. II. A comparison of migrants in New Zealand and non-migrants. The Tokelau Island migrant study.

The migration of 1381 Tokelauans 15 years and over to New Zealand leaving 811 in Tokelau, provided a unique opportunity to test centuries of speculation on the impact of environment on rheumatic disease. There was no change in all rheumatic complaints. The migrant men had more gout, joint pain following injury, and neck pain. The migrant women had more dorsal back pain. There was no change in the prevalence of clinically defined osteoarthritis (COA) despite positive associations with weight and higher weights in the migrants. Rheumatoid arthritis was infrequent in both populations. Low back pain was common but was not more common in migrants, though compensation payments are readily available in New Zealand and are not in the Islands.

International migration and biodemographical behaviour: a study of Italians in Belgium.

This paper describes the matrimonial and reproductive behaviour of Italians who migrated to Belgium after the Second World War. Migrants were either already married, or later became married, to other Italians. Among the children of migrants, men equally chose Italian or Belgian wives but women tended to prefer Italian partners. Italian-Belgian marriages were more frequent among the better educated groups. Family size is smaller among migrants marrying after migration and in heterogamous marriages. Significant differences in birth intervals are found when marriage occurred before or after migration, between generations, and between homogamous and heterogamous marriages.

An overview of the health status of migrants in France, in relation to their dietary practices.

OBJECTIVE: To review studies on the morbidity, mortality and nutrition of migrant populations in France. DESIGN: A systematic search of the bibliographic database Medline, and direct contact with associations and institutions concerned with migrants' health. RESULTS: In France, as in other host countries, migrants belong to the lowest socio-economic strata. They have on average better health and lower mortality than the local-born population. Health benefits are particularly noticeable in Mediterranean men, especially for affluence-related diseases such as cancer and cardiovascular diseases. North African men smoke as heavily as the local-born of the same occupational categories, and yet their mortality rates from lung cancer are notably lower. Such a paradox may be the result of a synergy between different phenomena such as the selection of the fittest applicants for immigration and the maintenance of healthy lifestyles from the countries of origin. In contrast, migrant women do not enjoy the same health advantages, possibly because they are less likely to be selected on the basis of their health and because they are often non-working. Adult migrants from southern Europe and North Africa report dietary practices consistent with the typical Mediterranean diet, which is renowned for its positive effects on health. CONCLUSIONS: The diet of Mediterranean adults living in France may partly explain the low rates of chronic diseases and high adult life expectancy observed in migrant men from northern Africa. Information about their diets might provide clues for the design of nutritional education campaigns aimed at low-income people.

Psychosocial factors in blood pressure variation: a comparative study of young Samoans.

Traditional peoples contacting modern cultures frequently experience increased levels of blood pressure. The aim of this investigation was to identify some acculturation-related psychosocial factors which might contribute to those elevations. Young Samoans living in a traditional village, in modernizing American Samoa, and as migrants in Hawaii were studied. Casual blood pressure, anthropometric measurements, and extensive interview data were collected. The most important factor predicting variation in blood pressure was body mass (BMI). This finding was particularly evident among the acculturated and migrant Samoans. In those locations women's abandonment of breast feeding may contribute to their higher BMI. Among acculturated and migrant women, measures of social support favored lower blood pressures. Among men in all locations a greater number of close social ties was linked to higher blood pressures with the exception of ties with parents. Parental ties were linked to substantially lower blood pressures. A knowledge of Samoan traditions favored lower blood pressure among migrant men, while knowledge of American culture favored higher pressures. Coping strategies and complaint behavior were also significant contributors in all locations.

Blood pressure patterns and migration: a 14-year cohort study of adult Tokelauans.

The longitudinal relation between blood pressure changes and migration experience has been studied in a cohort of 654 adult Tokelauans through three survey periods between 1968 and 1982. Migration from a subsistence life-style on a Pacific atoll to an urbanized Western life-style in New Zealand is associated with increases in body mass in both men and women. Both the systolic and diastolic blood pressures of migrant men are significantly higher than would be expected in this cohort on the basis of age when compared with the nonmigrants. This is consistent with a rise around the time of migration to a level which is then maintained, with the diastolic pressures taking longer than the systolic pressures to respond to the migration stimuli. Most of this rise in blood pressure may be attributed to weight gain, but a significant part of the diastolic pressure excess remains unexplained. This pattern is not exhibited by the women, which may be a reflection of the sex roles in this Polynesian society. These findings indicate a need for new immigrants to be encouraged not to gain weight when confronted with new dietary choices.

Migration, blood pressure pattern, and hypertension: the Yi Migrant Study.

Rural-urban migration provides an ideal opportunity to examine the effects of environment and genes on blood pressure. The effect of migration on the Yi people of China was studied. The Yi people live in a remote mountain area in southwestern China. In 1989, blood pressure was measured in 14,505 persons (8,241 Yi farmers, 2,575 urban Yi migrants, and 3,689 Han urban residents) aged 15-89 years. Different patterns were seen for men and women. Among the men, Yi farmers had the lowest mean blood pressure, the least rise in blood pressure with age (systolic blood pressure, 0.13 mmHg/year; diastolic blood pressure, 0.23 mmHg/year), and the lowest prevalence of hypertension (0.66%). In contrast, both Yi migrant men and Han men had higher levels of mean blood pressure, rise in blood pressure with age (Yi migrants: systolic pressure, 0.33 mmHg/year; diastolic pressure, 0.33 mmHg/year; Han: systolic pressure, 0.36 mmHg/year; diastolic pressure, 0.23 mmHg/year), and prevalence of hypertension (Yi migrants, 4.25%; Han, 4.91%). Among the women, however, mean systolic pressure was higher in Yi farmers than in Yi migrants or in Han. Diastolic pressure was similar among the three groups. However, the Yi farmer women's age-related rise in blood pressure (systolic pressure, 0.06 mmHg/year; diastolic pressure, 0.14 mmHg/year) and their prevalence of hypertension (0.33%) were lower than those in the other two groups. Yi migrant women had an intermediate rise in blood pressure with age (systolic pressure, 0.37 mmHg/year; diastolic pressure, 0.23 mmHg/year) and prevalence of hypertension (2.40%). Han women had the greatest rise in blood pressure with age (systolic pressure, 0.56 mmHg/year; diastolic pressure, 0.36 mmHg/year) and the highest prevalence of hypertension (4.76%). For both men and women, the above differences were only partially explained by age, body mass index, heart rate, smoking, and alcohol use. This study, using standardized methods, demonstrates an important effect of migration on rise in blood pressure with age and on the prevalence of hypertension.

The social constructions of sexuality: marital infidelity and sexually transmitted disease-HIV risk in a Mexican migrant community.

OBJECTIVES: This article explores the social context of the migration-related HIV epidemic in western Mexico. METHODS: Data collection involved life histories and participant observation with migrant women in Atlanta and their sisters or sisters-in-law in Mexico. RESULTS: Both younger and older women acknowledged that migrant men's sexual behavior may expose them to HIV and other sexually transmitted diseases.Younger Mexican women in both communities expressed a marital ideal characterized by mutual intimacy, communication, joint decisionmaking, and sexual pleasure, but not by willingness to use condoms as an HIV prevention strategy. CONCLUSIONS: Migrant Mexican women's commitment to an illusion of fidelity will hinder HIV prevention initiatives targeted toward them. Furthermore, the changing meanings of marital sex may make it harder to convince young couples to use condoms as an HIV prevention strategy. If the chain of heterosexual marital HIV transmission is to be interrupted in this community, prevention programs must target men.

'Between a rock and a hard place': applied anthropology and AIDS research on a commercial farm in Zambia.

Fieldwork on a commercial farm in southern Zambia, which was aimed at designing an HIV prevention program for farm workers, gradually exposed the nature of sexual liaisons between young girls, coming to work on the farm from the surrounding villages, and older migrant men workers. Before completing fieldwork, the anthropologist voiced her concern about the implications of these liaisons for the spread of STDs and HIV with the local rural community, farm management and farm workers. The immediate outcome of her intercessions was the decision by management to sack under-age workers. Although some members of the local community, including local research assistants, and some managers and workers welcomed this decision, others were angered by it. Caught between interest groups and conflicting guidelines, the anthropologist, it is argued, was in a no-win situation, 'between a rock and a hard place'. The paper proposes that the application of anthropological ethics in AIDS research needs some re-evaluation.

A comparison between Northern and Southern blacks residing in the North.

Differences between Southern and non-Southern blacks living in the North and West are considered for a wide variety of attributes such as employment, occupation, income, marital stability, and offspring's performance in school. Migrant blacks have generally more favorable rates than their Northern- and Western-born compatriots after standard domographic controls are applied to an unusually detailed set of cross-tabulations based on the One-Percent Sample Tapes for 1960. Perhaps the sharpest gap exists with respect to marital conditions; Southern blacks of both sexes are more likely to marry and, among those ever married, live more frequently with their spouses. Some of the results reported by earlier investigators require considerable modification; For example, the fact that Northern black men are less often at work than migrants has led to speculations about regional differences in work orientation among blacks, but a detailed analysis of labor force activity indicates this pattern does not hold for women. Likewise, the migrant income advantage is found to vary by education such that it is confined to those with low educational attainment. The use of sample tapes permits a novel analysis of differences between Northern-born blacks classified by whether they are second or at least third generation residents of the North (children of Southern- or Northern-born parents, respectively). For the attribute measured, school performance, the gap is essentially nil. Finally, an alternative is suggested to the existing causal interpretations of North-South gaps among black residents of the North. Reconsidered in particular are the higher labor force rates of migrant men and their more frequent employment in blue collar jobs;

Immigration policy and immigrant quality: empirical evidence from Canada.

"This paper examines the earnings of foreign-born and native-born men [in Canada] in an attempt to evaluate whether the decline in the quality [based on earnings] of Canadian immigrants is related to changes in the country-of-origin mix and the class (type) mix of immigrants....The analysis consists of two parts. The first part is based on individual data on earnings and socio-economic characteristics collected in the 1971 and 1986 Canadian Censuses.... In the second part of the analysis, additional regression equations are estimated, pertaining to the period 1968 to 1985, that relate these Census-based measures of immigrant quality to the country-of-origin and class mix of immigrants." The impact of changes brought about by the 1967 restructuring of the Canadian immigration system is analyzed.

Survey of condom-related beliefs, behaviors, and perceived social norms in Mexican migrant laborers.

This study reports findings from a survey of condom-related beliefs, behaviors, and perceived social norms in Mexican migrant laborers that live and work in the United States for extended periods of time. Snowball sampling was used to recruit 501 Mexican migrants from five "sending towns" in Jalisco, Mexico, with historically high rates of out-migration to the United States. Results showed that subjects reported few negative beliefs about condom use and high efficacy to use condoms in challenging sexual situations but social norms sanctioning condoms were limited. Results also revealed mixed knowledge of HIV transmission, poor knowledge of condom use, and higher condom use with occasional versus regular sex partners. Forty-four percent of male migrants reported sex with prostitutes while in the U.S., with married men reporting less condoms use with prostitutes than single men. It was concluded that condom promotion efforts with Mexican migrants should concentrate on men to encourage consistent use with occasional sex partners, including prostitutes. AIDS prevention education should be provided with sensitivity to the language needs, limited education, and extreme social and geographic marginality of this highly underresearched Latino population.

Sources of immigrants' language proficiency: Australian results with comparisons to the Federal Republic of Germany and the United States of America.

Recent research on immigrants in the Federal Republic of Germany and the US suggests that their amount of education, the country in which they attained it, and their labor force experience both before and after migrating all have important effects on their skills in the language of the host country. This paper explores those influences on the English language proficiency of 4 groups of immigrants to Australia: 1) those from Northwestern Europe, 2) Eastern Europe, 3) the Mediterranean basin, and 4) the Third World. The data are drawn from the 1% public use sample of the 1981 Australian census. The models are flexible ordinary least squares specifications that permit a variety of curvilinear na interaction effects. The results generally parallel those for the Federal Republic of Germany and the US. 1 important difference from the US is that the harmful effect of foreign labor experience is greater than the beneficial effect of labor force experience in the host country.

Migration from the northeast to the southeast in Brazil: do migrants succeed?

"In this paper 1980 [Brazilian] Census microdata are used to evaluate the experiences of males who moved from the Northeast to the Southeast in the post- 'miracle' period. Using regression analysis, migrant earnings are compared to those of persons who remain in the Northeast, to estimate the average earnings gain from relocating. These results are then disaggregated by education, age at migration, period of residence, and particular sending and receiving location, to provide more specific information on which groups benefit most. Wide variation in gains is observed, but substantial improvements in earnings are reported in most cases."

A dynamic model of interregional migration flows in Great Britain.

"The purpose of this study is to construct a dynamic model of migration in Great Britain based on time-series data developed from the records of the National Health Service Center Register (NHSCR) on male migrants of working age between 1975 quarter 2 and 1979 quarter 2." A two-stage methodology "was developed...which differed in many important respects from the techniques adopted in previous studies of time-series migration flows. Regional push and pull factors were derived on the basis of the revealed preferences of migrants, using a two-stream gravity model, and then subsequently related to vectors of regional characteristics, within a general dynamic setting. Factors affecting the overall volume of migration nationally were separated out from those determining the internal direction of migration flows, and factors affecting distance sensitivity. Despite weaknesses in the available data set, the results achieved...suggested many interesting dynamic responses, implying lengthy and important lags in the estimated relationships."
