Spouse correlations in cardiovascular risk factors and the effect of marriage duration.

Spouse correlations in cardiovascular risk factors were investigated using data on 2,836 spouse pairs collected in the Busselton Population Health Surveys over the period 1966-1981. The risk factors considered were systolic blood pressure, diastolic blood pressure, body mass index, triceps fatfold, cholesterol, and forced expiratory volume (1 second). Statistically significant positive correlations (p < 0.01) were found for all (age-adjusted) variables. There was a statistically significant decreasing trend in the correlations for systolic blood pressure with marriage duration (trend p < 0.01). Although no other variables showed statistically significant trends, the correlations for diastolic blood pressure (p = 0.29), body mass index (p = 0.14), and forced expiratory volume (p = 0.16) also decreased with marriage duration, and correlations for cholesterol (p = 0.61) and triceps fatfold (p = 0.99) increased with marriage duration. These results suggest that there is spousal concordance in cardiovascular risk factors. The lack of consistent increasing trends in the correlations with marriage duration suggests that assortative mating may be a more likely explanation than the sharing of a common environment.

Does an effect of marriage duration on pre-transition fertility signal parity-dependent control? An empirical test in nineteenth-century Leuven, Belgium.

It has been demonstrated for many pre-industrial populations that the age at marriage, or marriage duration, influences age-specific marital fertility but the reason for this remains unclear. Among the several mechanisms that may be responsible, the following are often cited: secondary sterility or increased subfecundity associated with parity; declining coital frequency; the age difference between the spouses; and, importantly, parity-dependent fertility control. If the latter mechanism were partly responsible for the marriage-duration effect in pre-transition populations, it would contradict the concept of the modern fertility transition as the evolution (or revolution) from parity-independent to parity-dependent fertility. The study presented in this paper investigates the relative importance of these alternative explanations. The application of multivariate Poisson regression to the fertility data from two birth cohorts in the Belgian city of Leuven shows that a linearly declining or even concave age-specific fertility pattern, disaggregated by age at marriage, does not imply parity-dependent fertility limitation.

Marriage duration, marital adjustment and psychological symptoms: a cross-sectional study.

One hundred and nine couples completed questionnaire measures of psychological symptoms, personality, and marital adjustment. They were divided into groups of short, intermediate, and long marriage duration. Psychological symptoms and marital adjustment remained fairly stable over time, although wives scored significantly worse than husbands on most measures in the intermediate duration group. In the short marriages, half the variance in marital satisfaction was predicted by the partner's marital questionnaire score, but when this variable was eliminated from the regression equation, psychological symptoms (phobic anxiety in wives and depression in husbands) were the main predictors of marital satisfaction. In the intermediate group, hostility levels were the main predictors of marital satisfaction. In the long marriages, marital satisfaction was predicted mainly by personality factors (assertiveness in husbands and personal flexibility in wives) and by levels of generalized anxiety. The findings suggest that couples who constructively resolve difficulties in expressing hostility within marriage are more likely to remain married than those who fail to do so.

Searching for a two-factor model of marriage duration: commentary on Gottman and Levenson.

Gottman and Levenson (2002) report a number of post hoc ordinary least squares regressions to "predict" the length of marriage, given that divorce has occurred. We argue that the type of statistical model they use is inappropriate for answering clinically relevant questions about the causes and timing of divorce, and present several reasons why an alternative family of models called duration models would be more appropriate. The distribution of marriage length is not bimodal, as Gottman and Levenson suggest, and their search for a two-factor model for explaining marriage length is misguided. Their regression models omit many variables known to affect marriage length, and instead use variables that were pre-screened for their predictive ability. Their final model is based on data for only 15 cases, including one unusual case that has undue influence on the results. For these and other technical reasons presented in the text, we believe that Gottman and Levenson's results are not replicable, and that they should not be used to guide interventions for couples in clinical settings.

Simultaneous equations for hazards: marriage duration and fertility timing.

"This paper develops an approach to simultaneity among hazard equations which is similar in spirit to simultaneous Tobit models. It introduces a class of continuous time models which incorporates two forms of simultaneity across related processes--when the hazard rate of one process depends (1) on the hazard rate of another process or (2) on the actual current state of or prior outcomes of a related multi-episode process. This paper also develops an approach to modeling the notion of 'multiple clocks' in which one process may depend on the duration of a related process, in addition to its own. Maximum likelihood estimation is proposed based on specific parametric assumptions. The model is developed in the context of and empirically applied to the joint determination of marital duration and timing of marital conceptions."

Changes in widowhood and divorce and expected durations of marriage.

A new interpretation of mathematical formulas developed by Keyfitz illustrates how the concept of entropy (H) can be applied to the analysis of marriage dissolution. The quantities H(divorce) and H(widowhood) indicate the changes in marriage duration which would result from small, constant changes in duration-specific divorce and widowhood rates, respectively. An examination of values for the United States, Nepal and Colombia illustrates the utility of H(i) in assessing the impact of changes in widowhood and divorce and clarifies the relationship between H and changes in life expectancy.

Period and cohort effects on divorce rates.

The author analyzes the demographic dimensions of divorce. A model is developed to estimate "the isolated effects of marriage duration, marriage cohort, and divorce period...on divorce probabilities over time [using data for Austria, Denmark, Finland, the Netherlands, Sweden, and Switzerland].... Crude divorce rates (divorces per 1,000 married couples) in the six countries for the period 1946-1984 are reviewed, followed by a very brief review of some of the literature on period and cohort effects in general, and divorce in particular. The [second] section describes the data. The third section presents and discusses the results."
