Social class inequalities in perinatal outcomes: Scotland 1980-2000.

OBJECTIVE: To examine social class inequalities in adverse perinatal events in Scotland between 1980 and 2000 and how these were influenced by other maternal risk factors. DESIGN: Population based study using routine maternity discharge data. SETTING: Scotland. PARTICIPANTS: All women who gave birth to a live singleton baby in Scottish hospitals between 1980 and 2000 (n=1,282,172). MAIN OUTCOME MEASURES: Low birth weight (LBW), preterm birth, and small for gestational age (SGA). RESULTS: The distribution of social class changed over time, with the proportion of mothers with undetermined social class increasing from 3.9% in 1980-84 to 14.8% in 1995-2000. The relative index of inequality (RII) decreased during the 1980s for all outcomes. The RII then increased between the early and late 1990s (LBW from 2.09 (95%CI 1.97, 2.22) to 2.43 (2.29, 2.58), preterm from 1.52 (1.44, 1.61) to 1.75 (1.65, 1.86), and SGA from 2.28 (2.14, 2.42) to 2.49 (2.34, 2.66) respectively). Inequalities were greatest in married mothers, mothers aged over 35, mothers taller than 164 cm, and mothers with a parity of one or more. Inequalities were also greater by the end of the 1990s than at the start of the 1980s for women of parity one or more and for mothers who were not married. CONCLUSION: Despite decreasing during the 1980s, inequalities in adverse perinatal outcomes increased during the 1990s in all strata defined by maternal characteristics.

Changes in diet and coronary heart disease mortality among social classes in Great Britain.

Coronary heart disease (CHD) mortality has declined in Britain since the early 1970s and followed a reduction in dietary fat intake in the population. We attempted to determine whether there have been changes in dietary fat intakes by social classes and to see whether they correspond to social class changes in CHD mortality, where the greatest reduction has been in the upper social class groups. Dietary fat intake was specially obtained by social class on a household basis from the National Food Survey (NFS) for 1974 and 1981. The decline in saturated fat intake and increase in polyunsaturated fat is shown to have occurred in each social class group, although it was not possible to examine the data separately for men and women. In contrast, the decline in the proportion of current smokers between 1974 and 1980 (from the General Household Survey) was greatest in the higher social classes. Rates of CHD mortality showed the greatest decline among men in social classes I & II over the period 1969/73 to 1979/83. However, despite some problems in the interpretation of the data collected by the NFS, this study shows that recent social class trends in dietary fat intakes are unlikely to account for the differential changes in CHD mortality. Changes in the prevalence of smoking among social classes are more consistent with the change in CHD mortality.

Trends in cigarette smoking among coronary patients between 1961 and 1975.

Between 1961 and 1975 the proportion of cigarette smokers among male patients with acute coronary heart disease showed a progressive decline from 87.1 to 66.1%. There was a corresponding increase in the proportion of ex-smokers and non-smokers. Factors which might have accounted for this trend were examined. Changing diagnosis, altered prevalence of other risk factors and social class changes in patient referral would not appear to have accounted for the observed smoking trends. It is suggested that the observed trends in cigarette-smoking habits may be real and that they may represent a change in the epidemiological pattern of coronary heart disease in Ireland.

Marriage and its transition in Bangladesh.

The author examines developments in marriage patterns in Bangladesh in light of social, cultural, and economic conditions. Previous literature on the subject is used to discuss Muslim marriage, Hindu marriage, child marriage, mate selection and social mobility, and the question of a marriage squeeze. "The analysis presents evidence that the society is experiencing a change in its family formation, mating process and family type. This transition is to some extent towards the characteristics of [the] Western World, but in a poor economy. Part of this transition is due to the effect of modernization and part due to increasing poverty."

Visualizing changing social structure from a census.

"In this paper it is shown how new visualization techniques are being used to analyze the first results of the British 1991 Census and other large data sets." The focus is on new ways to show how localities develop over time. The author suggests that this cannot be done effectively using traditional quantitative techniques. "Pictures are needed to show how different processes occur in different places, and holistic patterns need also to be seen without generalizing out the detail. Neither traditional thematic mapping nor commercial geographic information systems can do this well. Spatial visualization is an alternative approach in which the researchers choose what they wish to see and how they wish to view it. Many problems require new methods of visualization for their exploration. A new census presents us not only with new statistics, but also with the opportunity and impetus to develop radically different ways of envisioning information to reveal more fully the human facts contained within a mass of social statistics."

A cohort analysis of Korean immigrants' class backgrounds and socioeconomic status in the United States.

"In this article, I first survey briefly the history of Korean immigration to the United States from 1903 to the present. Second, I explain the motivations and entry mechanisms that brought Korean immigrants into the United States. Third, I document and explain the changes in the class backgrounds of Korean immigrants during the last three decades. Finally, I examine how such changes have affected the patterns of social and economic adaptation among the different waves of immigrants."

[Other perception and play-group entry in a preschoolers class].

Kindergarten children accumulate classmate information through their experience of spending time and doing things together. In the course of preschool lives, a class changes from an aggregation of children to a peer group with own history of interaction and involvement. In such a peer group, whether a child becomes a play-group member is likely to depend not only on his/her social skills, but also on perception based on classmate information, especially whether the other is seen as someone whom the child would like to play with. Relationship between such perception and play-group entry was investigated in a kindergarten class for two years, from entrance as four-year olds to graduation. At the beginning, the two were unrelated, but they became related in later periods. A child was accepted into a play group without trouble when the group members thought he/she was someone they would like to play with. These results supported the hypothesis that other perception based on classmate experience and group history influenced the entry into classroom play groups.

A longitudinal perspective of the relationship between perceived motivational climate, goal orientations, and strategy use.

Achievement goal theory suggests that goal orientations and the perceived motivational climate may influence one another and other motivational variables over time. Therefore, the purpose of this study was threefold: (a) to examine the relationship between perceived motivational climate and goal orientations over time (b) to investigate how goal orientations may fluctuate when the climate was in opposition to the initial goal orientation, (c) to determine how the climate may impact practice strategies. A set of inventories was administered to 162 college students at preselected times throughout several 16-week physical activity classes. Changes occurred in students' goal orientations, particularly when the perceived motivational climate was in opposition to their goal orientation. Aspects of the task-involving climate positively predicted practice strategies.

Modelling the social dynamics of a sex industry: its implications for spread of HIV/AIDS.

A theoretical model is proposed for a community which has the structure of two classes (direct and indirect) of commercial sex workers (CSW), and two classes of sexually active male customers with different levels of sexual activity. The direct CSW's work in brothels while the indirect CSW's are based in commercial establishments such as bars, cafes, and massage parlours where sex can be bought on request and conducted elsewhere. Behaviour change and the resulting change of activity class occurs between the two classes of CSW's and two classes of males under the setting of the proliferation of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome epidemic and the subsequent intervention programmes. In recently years, this phenomenon has been observed in several countries in Asia. Given the lower levels of condom use and higher HIV prevalence of the indirect CSW's, ascertaining the impact of this change in the structure of the sex industry on the spread of HIV is the main focus of this paper. The complete analysis of the disease-free model is given. For the full model, local analysis will be performed for the case of preferred mixing without activity class change, as well as the case with activity class change and restricted mixing. The basic reproduction number for the spread of epidemic will be derived for each case. Results of biological significance include: (i). the change of behaviour by the CSW's has a more direct effect on the spread of HIV than that of the male customers; (ii). the basic reproduction number is obtained by considering all possible infection cycles of the heterosexual transmission of HIV which indicates the importance of understanding the sexual networking in heterosexual transmission of HIV; (iii). the social dynamics of the sex industry is not just a simple 'supply and demand' mechanism driven by the demand of the customers, hence highlighting the need for further understanding of the changing structure of the sex industry. The main points of this work will be illustrated with numerical examples using the HIV data of Thailand.
