A study of the association of Epstein-Barr virus with Burkitt's lymphoma occurring in a Chinese population.

There is a strong association (approximately 95%) of endemic Burkitt's lymphoma with Epstein-Barr virus (EBV), whereas the association is weak for the sporadic form occurring in Western countries (approximately 15%). In the Middle East, North Africa and South America, 60-80% of Burkitt's lymphomas harbour EBV. These epidemiological differences suggest that either the endemicity of EBV or socio-economic conditions, or both, may influence the pathogenetic role of EBV in Burkitt's lymphoma. Since only meagre data are available on Asians, this study was performed to address this issue by studying cases from Hong Kong, where EBV seroconversion occurs in the first few years of life but the socio-economic conditions approach those of Western countries. In situ hybridization for EBV encoded RNAs (EBERs) was performed on paraffin sections of 18 cases of Burkitt's lymphoma. Labelling of the neoplastic cells was detected in five cases (27.7%). In contrast, among 54 cases of B-cell lymphomas of various subtypes studied for comparison, signals for EBER were detected in only one case each of T-cell-rich large B-cell lymphoma, anaplastic large cell lymphoma and Reed-Sternberg-like cells occurring in B-cell chronic lymphocytic leukaemia/small lymphocytic lymphoma. The strong labelling with oligo-dT probe (which hybridized with the polyadenylated ends of mRNA) in all cases suggested that the negative results were genuine and not due to poor preservation of RNA in the tissues. Thus, among B-cell neoplasms occurring in Chinese, Burkitt's lymphoma shows a statistically stronger association (P < 0.01) with EBV than with other types of B-cell lymphoma.(ABSTRACT TRUNCATED AT 250 WORDS)

The economic crisis and its impact on health and health care in Latin America and the Caribbean.

The economic crisis that struck most Latin American and Caribbean countries beginning in 1982 has caused sharp reductions in domestic investment and in imports; domestic consumption has been less affected, while public sector spending has responded in different degrees in different countries. In general, public spending on health decreased, sometimes quite dramatically, but some countries were able to maintain the real value of noninvestment spending for health by central governments. It is much harder to tell what may have happened to output of health services, and still harder to know how health status has been affected. Scattered evidence suggests two conclusions. First, worsened economic conditions can seriously damage health status, with effects on infant mortality and on the patterns of disease and death, especially for children. Second, these repercussions do not have to occur, and public programs designed specifically to maintain basic health services and to assure adequate nutrition are effective in offsetting the worst consequences of economic hardship.

Some aspects of secular changes in Hungary over the twentieth century.

Growth and maturation are considered the most reliable indicators of health status. Their progression rates in turn are strongly influenced by nutrition and socio-economic status, a well-documented relationship. The pattern of the so-called positive secular changes, i.e. the increase in size and earlier maturation, fits the populations' historical model of economic development very well. The historical, political and economic changes occurring in this century in Hungary have had a remarkably strong impact. Until World War I Hungary was an agrarian part of the Austro-Hungarian monarchy, its ethnic composition was most variegated. Both World Wars caused fundamental changes, namely in respect of post-war Hungary they were associated with marked territorial losses and considerable population mobility. In interpreting the developmental differences in the data collected before and after these wars one should take account of the important facts that, in addition to the changes in socio-economic conditions, affected the gene pool of the populations in Hungary. Over the past 100 years profound changes have occurred in the mean body size, growth rate and timing of maturation of the country's population. This paper is a brief analytic summary of the tendencies observed in adult stature, maturation and some socio-economic conditions. It also compares the cohorts of sub-populations as reflected by the reviewed reports. In summarizing the change in adult stature estimated by the data on recruits, soldiers and students of higher education, it could be stated that adult mean stature had become markedly taller in Hungary since the end of the fifties. However, any estimation of the absolute increment and the exact rate is severely biased by the variable character of the samples' representativeness. Similar problems arose in dealing with sexual maturation, because the retrospective and status-quo methods of assessment were found incomparable. Nevertheless, menarche was observed to have shifted to an appreciably younger age lately, a trend that by the end of the 20th century seemed to have reached a more or less stable level.

Violent tactics in family conflict relative to familial and economic factors.

A study was conducted to examine the social, economic, and family process factors which may be associated with families' use of violent tactics in conflict within an homogeneous population in the Appalachian region of southwestern Virginia. The primary hypothesis stated that economic conditions as set by the employment status of parents would be a significant factor in predicting use of violence in the resolution of family conflict. The study employed a questionnaire modeled after that used in a national study of family violence conducted by Straus, Gelles, and Steinmetz in 1980 with additional items developed to assess regional family processes and economic conditions. 114 boys and 161 girls ranging in age from 15 to 17 yr. participated. Statistical analysis confirmed the major hypothesis: in families where the father was unemployed, there was greater than expected frequency of reported violent interactions. Additional findings included associations between previous generation's abuse and use of violent interactions as well as sex of subject and use of violent interactions.

Experiments in transforming the global workplace: incentives for and impediments to improving workplace conditions in China.

This article highlights current economic conditions in China and analyzes existing obstacles to improving workplace conditions and labor practices. There are significant disincentives to strengthening workplace protections, and downward pressures are currently worsening conditions in a number of economic sectors. However, there are also potential strategies for motivating multinational corporations (MNCs) and Chinese government agencies to improve workplace conditions and to implement international and national laws and corporate codes of conduct. Four key principles are discussed that hold promise for creating incentives and sustainable mechanisms to improve factory conditions: transparency, verification, and accountability for MNCs and Chinese government agencies, and greatly strengthening worker participation.

Promoting health and preventing disease: an international perspective on youth health promotion.

PURPOSE: To advocate strategies to promote the health of young people that include action to create supportive social and economic conditions, alongside more traditional actions to strengthen individual capacity to protect health. METHODS: Analysis of different strategies for youth health promotion from different countries, including education, public policies, laws, and regulations that protect young people from exploitation and physical harm, and enhance their capacity to make healthy lifestyle choices. RESULTS: Access to education and the promotion of basic literacy are, in their own right, important public health goals. Beyond this, efforts to promote health through schools should focus on the creation of an integrated and mutually reinforcing set of experiences for young people, including classroom health education, the creation of a safe and healthy physical environment, and provision of appropriate school health services. The creation of supportive social and economic conditions are also essential, and require political action through the development of public policy. Such policies include restricting access to tobacco, alcohol, and illicit drugs, improving access to essential health services; and regulation of economic exploitation of young people. CONCLUSIONS: Health promotion is inherently political. Health professionals have to find ways to become more effective political advocates for young people. This should be reflected in the education of health professionals and educators, and in the work of agencies and professional associations.

[A study of mental health in community-dwelling older persons].

We conducted a comprehensive evaluation of the mental health of community-dwelling elderly people, and encompassed the physiological, psychological, social and environmental aspects of their lives. The study used a questionnaire similar to the one used by Matsubayashi et al in their study in Kahoku-cho. The Japanese version of General Health Questionnaire 12 (GHQ-12) was used to evaluate mental health. Responses were received from 2,799 (81.5%) of 3,432 Numura-cho residents. After eliminating inadequate responses, 1,298 (37.8%) (586 men and 712 women) were analyzed. By setting mental health disorder, defined as a value of GHQ-12 exceeding 4.0, as the target variable, logistic regression analysis was conducted using the background factors as explanatory variables. Information related function (odds ratio: 0.45; 95% CI: 0.30-0.66), living with others (0.36, 0.14-0.94), presence of spouse (2.52, 1.14-5.59), economic condition (0.45, 0.22-0.91), family relationship (0.17, 0.05-0.52), work & sports (0.31, 0.14-0.67) and emotional support (0.67, 0.48-0.95) were found to be explanatory variables for mental health in the young elderly; as were activities of daily living (0.52, 0.35-0.79), Information related function (0.56, 0.35-0.90) and emotional support (0.37, 0.24-0.58) in the old elderly; as were activities of daily living (0.37, 0.19-0.70) and economic condition (0.32, 0.11-0.95) in the very old. For amelioration of the mental health of elderly persons living in the community, attempts should be made to improve the background factors clarified by the present study by efficiently utilizing health, medical and welfare services.

Ageing, lifestyle modifications, and cardiovascular disease in developing countries.

Developing countries face the double menace of still prevalent infectious diseases and increasing cardiovascular disease (CVD) with epidemic proportions in the near future, linked to demographic changes (expansion and ageing), and to urbanisation and lifestyle modifications. It is estimated that the elderly population will increase globally (over 80% during the next 25 years), with a large share of this rise in the developing world because of expanding populations. Increasing longevity prolongs the time exposure to risk factors, resulting in a greater probability of CVD. As a paradox, increased longevity due to improved social and economical conditions associated with lifestyle changes in the direction of a rich diet and sedentary habits in the last century, is one of the main contributors to the incremental trend in CVD. The variable increase rate of CVD in different nations may reflect different stages of "epidemiological transition" and it is probable that the relatively slow changes seen in developing populations through the epidemiological transition may occur at an accelerated pace in individuals migrating from nations in need to affluent societies (i.e. Hispanics to the USA, Africans to Europe). Because of restrained economic conditions in the developing world, the greatest gains in controlling the CVD epidemic lies in its prevention. Healthy foods should be widely available and affordable, and healthy dietary practices such as increased consumption of fresh fruits and vegetables, reduced consumption of saturated fat, salt, and simple sugars, may be promoted in all populations. Specific strategies for smoking and overweight control may be regulation of marketed tobacco and unhealthy fast food and promotion of an active lifestyle. Greater longevity and economic progress are accompanied by an increasing burden of CVD and other chronic diseases with an important decrease in quality of life, which should question the benefit of these additional years without quality.

The influence of social class on parity and psychological reactions in women coming for induced abortion.

OBJECTIVE: To test the hypothesis that the correlation between legal abortion and socio-economic conditions, known from the time when abortion was restricted, has current validity. To evaluate the effect of social class on network support and psychological reactions. DESIGN: Consecutive sampling and semistructured personal interviewing. SUBJECTS: 444 women living in the city of Gothenburg and applying for legal termination of pregnancy in the first trimester. SETTING: The department of gynaecology at a university hospital with primary care responsibility for legal abortions. RESULTS: The 667 health administration districts of Gothenburg were ranked into four groups according to the mean income. Women living in lower socio-economic districts were younger. Irrespective of age, previous experience of induced abortion was more common among them (p < 0.001). Unsatisfactory network response or support was common (37%), but equally shared between the social classes. Discontinuation of oral contraception during the previous six months was twice as common among teenagers (40.0%) as among other women (p < 0.001) but without social differences. Pitman's permutation test was used for statistical analyses. CONCLUSION: Socio-economic conditions have a strong and inverse correlation to previous experience of induced abortion. Psychological reactions and needs did not vary with class.

Serum vitamin A in relation to socio-economic, demographic and dietary characteristics in Bangladeshi children.

The purpose of this study was to examine socio-economic conditions, demographic factors, use of vitamin A capsules and dietary practices in relation to the risk of low serum vitamin A. One hundred and twenty four night blind cases were identified by parents in a cross-sectional survey in Bangladesh in 1992. Age-, sex- and neighbourhood-matched controls were selected. Venous blood was collected from 87 cases and 97 controls for the determination of serum vitamin A. Information about socio-economic conditions, demographic factors, use of vitamin A capsules and dietary practices was obtained by interview. The level of serum vitamin A was strongly related to age and consumption of beta-carotene rich foods. The preschool years (2-6 years) are important risk periods for vitamin A deficiency among children. We conclude that long-term prevention of vitamin A deficiency should rely on efforts to improve local diet.

Longevity index (LI%) and centenarity index (CI%): new indicators to evaluate the characteristics of aging process in the Italian population.

Centenarians represent a group of population displaying the most rapid expansion. This progressive increase of the presence of centenarians is a multi-factorial phenomenon, which is due to the improvements of the environmental conditions and the life style and also to the progress of the medical science. In order to obtain a more reliable estimate of the longevity per gender and territorial entities, we propose two new indicators. (i) The ratio between the ultranonagenarians and the total population above 65 years old (called longevity index: LI%); (ii) the ratio between the centenarians and the total population above 90 years old (called centenarity index: CI%). An analysis of the data of the Italian National Office of Statistics (ISTAT, ) using these two indicators demonstrates that the subjects above the age of 90 are more frequent in the regions of Central and Northern Italy, which are more developed regarding the economic conditions and technological progress. Nevertheless, the Southern and Insular regions of Italy have a higher occurrence of centenarians among the ultranonagenarian population, and also a higher prevalence of male centenarians, as compared to the northern regions. This demonstrates that achievement of the threshold of 100 years old does not require only particular socio-economic conditions, but also an adequate climate and environment, as well as a favorable genetic composition.

Socio-biological correlates of bacteriuria in Saudi pregnant women.

Prevalence and socio-biological correlates of bacteriuria in Saudi pregnant women were investigated at King Fahd Hospital of the University, Al-Khobar, Saudi Arabia. Midstream sample specimens of urine were used for identification of significant bacteriuria (greater than or equal to 10.5 organisms of single species per milliliter of urine). The prevalence of bacteriuria was found to be 14.2%. It was more common in women below 20 years of age and among the parous as against the nullipara women. Bacteriuria was significantly associated with socio-economic conditions. It was higher in those with a low family income, of large family size (10+) and living in over-crowded conditions. Only one-fourth (25.8%) of bacteriuric women were symptomatic. Almost half (45.8%) had a past history of urinary tract infection. To identify the problem of urinary tract infection in a vulnerable group of women, as well as to reduce the load on laboratory facilities, it is suggested that routine antenatal screening for bacteriuria should be advocated on a selective basis, i.e. for the young teenage parous women, those coming from disadvantaged socio-economic conditions and in patients with a past history of urinary tract infection.

Exporting labor: the impact of expatriate workers on the home country.

The economic impact of emigration on the source country is analyzed through a literature review and a discussion of costs, benefits, and public policy implications. It is noted that "information collected from different sources and settings is needed for cross-validation of assessments and conclusions. Second....the cost/benefit analysis of emigration should be undertaken on a case by case basis. Third...these costs and benefits must be assessed in a long-term framework that considers the socio-economic conditions and the goals of the country....Fourth, effective governmental policies...need to recognize that emigrants generally are highly motivated people [who] are adept at overcoming legal or other obstacles in their path."

Ethnic differences in self reported health in Malmö in southern Sweden.

STUDY OBJECTIVE: The aim of this study was to investigate ethnic differences in self reported health in the city of Malmö, Sweden, and whether these differences could be explained by psychosocial and economic conditions. DESIGN/SETTING/PARTICIPANTS: The public health survey in Malmö 1994 was a cross sectional study. A total of 5600 people aged 20-80 years completed a postal questionnaire. The participation rate was 71%. The population was categorised according to country of origin: born in Sweden, other Western countries, Yugoslavia, Poland, Arabic speaking countries and all other countries. The multivariate analysis was performed using a logistic regression model in order to investigate the importance of possible confounders on the differences by country of origin in self reported health. Finally, variables measuring psychosocial and economic conditions were introduced into the model. MAIN RESULTS: The odds ratios of having poor self reported health were significantly higher among men born in other Western countries, Yugoslavia, Arabic speaking countries and in the category all other countries, as well as among women born in Yugoslavia, Poland and all other countries, compared with men and women born in Sweden. The multivariate analysis including age and education did not change these results. A huge reduction of the odds ratios was observed for men and women born in Yugoslavia, Arabic speaking countries and all other countries, and for women born in Poland after the introduction of the social network, social support and economic factors into the multivariate model. CONCLUSIONS: There were significant ethnic group differences in self reported health. These differences were greatly reduced by psychosocial and economic factors, which suggest that these factors may be important determinants of self rated health in certain minority groups.

Determinants of short-term fluctuations in nuptiality in Sweden, 1751-1913: application of multivariate ARIMA models.

"This study examines the determinants of short-term fluctuations in nuptiality in Sweden from 1751 to 1913, using ARIMA [Auto Regressive Integrated Moving-Average] models.... The following general patterns prevailed throughout the period 1751-1913: both better economic conditions (good harvests and lower rye prices) and higher mortality (leading to more remarriages, and enabling first marriages through inheritance) were followed by higher nuptiality. In addition, emigration of single persons after 1850 was inversely related to nuptiality." (SUMMARY IN FRE)

[Child malnutrition and maternal overweight in same households in poor urban areas of Benin].

The coexistence of child malnutrition and maternal overweight in the same households typifies rapid nutrition transition in developing countries (DCs). It is reportedly less common in Africa than in Latin America or Asia, but the phenomenon is still little documented. The purpose of our study in poor urban neighbourhoods of the capital city of Benin (West Africa) was to assess the magnitude of the overlap of child protein-energy malnutrition (PEM) and maternal overweight within households, and to compare these households with other nutritional phenotypes in terms of socio-economic circumstances and diet quality. Our hypothesis was that both child PEM and maternal overweight could stem from poor socio-economic conditions, including lack of sanitation, and poor diet quality. Food diversity was used as an index of diet quality, or the qualitative dimension of food security. A random sample of 148 households that included a least the biological mother, one child between 6 and 59 months of age and a second one between 5 and 11 years was selected in two poor neighbourhoods of the capital city of Cotonou to assess the prevalence of "double burden" households and of other nutritional phenotypes of households: with PEM only in at least one child; with maternal overweight only; and without PEM or overweight. Body weights and heights of mothers and of the two targeted children were measured. As long as one child had low weight-for-height or height-for-age (z-score <-2.0), the household came under the "PEM" type. In mothers, overweight was defined as body mass index (BMI) > or = 25, obesity > or = 30 and chronic energy deficiency <18.5. We retained 126 households for interviews with mothers on socio-economic circumstances and food diversity. A socio-economic status (SES) score was constructed on the basis of household amenities and maternal education. Food insecurity was based on reported shortage of food in the last year in the household. Based on the frequency of consumption of 13 different food groups in the previous week, a food diversity score was computed. Overall 35.5% of children were malnourished, and school-age children had a worse nutritional status than under-5 children: 41% and 30% PEM (chronic or acute or both), respectively. The rate of maternal overweight was 39.1% including 15.5% of obesity. Child PEM coexisted with maternal overweight or obesity in 16.2% of the households; 27.7% of households had PEM only, 23% overweight only, 20.3% showed no malnutrition or overweight, and 12.8% had an underweight mother. Maternal BMI status was significantly associated with both children's weight-for-height z-score, particularly the elder one. The rate of child malnutrition, particularly wasting, was significantly higher among underweight mothers and lower in overweight mothers . Underweight mothers were merged with mothers with BMI < or = 25 for the remaining analyses. Households with overweight mothers tended to enjoy relatively better socio-economic conditions--higher SES, higher maternal education, less food insecurity, better household sanitation; they also tended to have a more diversified diet. This is in contrast with PEM households. Dual burden households shared several socio-economic features with the PEM households, except for a higher (not significant) SES score. Dual burden households also had the lowest food diversity score of all household types. Logistical regression models revealed that a relatively higher SES level was associated with a higher likelihood of maternal overweight in PEM households, whereas poor household sanitation increased the odds of PEM among maternal overweight households. Food diversity appeared significantly associated with a lower likelihood of dual burden in all types of households. The study highlights the importance of addressing the double burden of malnutrition and overweight even in poor areas of low income countries of West Africa. It suggests that prevention efforts should be aimed at improving diet quality and sanitation in poor urban households.
