High-density lipoprotein 17beta-estradiol fatty acyl esters and phytoestrogens : Impact on reverse cholesterol transport and women's cardiovascular health

Reverse cholesterol transport (RCT) is an important function of high-density lipoproteins (HDL) in the protection of atherosclerosis. RCT is the process by which HDL stimulates cholesterol removal from peripheral cells and transports it to the liver for excretion. Premenopausal women have a reduced risk for atherosclerosis compared to age-matched men and there exists a positive correlation for serum 17β-estradiol (E2) and HDL levels in premenopausal women supporting the role of E2 in atherosclerosis prevention. In premenopausal women, E2 associates with HDL as E2 fatty acyl esters. Discovery of the cellular targets, metabolism, and assessment of the macrophage cholesterol efflux potential of these HDL-associated E2 fatty acyl esters were the major objectives of this thesis (study I, III, and IV). Soy phytoestrogens, which are related to E2 in both structure and function, have been proposed to be protective against atherosclerosis but the evidence to support these claims is conflicting. Therefore, another objective of this thesis was to assess the ability of serum from postmenopausal women, treated with isoflavone supplements (compared to placebo), to promote macrophage cholesterol efflux (study II). The scope of this thesis was to cover the roles that HDL-associated E2 fatty acyl esters have in the cellular aspects of RCT and to determine if soy isoflavones can also influence RCT mechanisms. SR-BI was a pivotal cellular receptor, responsible for hepatic and macrophage uptake and macrophage cholesterol efflux potential of HDL-associated E2 fatty acyl esters. Functional SR-BI was also critical for proper LCAT esterification activity which could impact HDL-associated E2 fatty acyl ester assembly and its function. In hepatic cells, LDL receptors also contributed to HDL-associated E2 fatty acyl esters uptake and in macrophage cells, estrogen receptors (ERs) were necessary for both HDL-associated E2 ester-specific uptake and cholesterol efflux potential. HDL-containing E2 fatty acyl esters (E2-FAE) stimulated enhanced cholesterol efflux compared to male HDL (which are deficient in E2) demonstrating the importance of the E2 ester in this process. To support this, premenopausal female HDL, which naturally contains E2, showed greater macrophage cholesterol efflux compared to males. Additionally, hepatic and macrophage cells hydrolyzed the HDL-associated E2 fatty acyl ester into unesterified E2. This could have important biological ramifications because E2, not the esterified form, has potent cellular effects which may influence RCT mechanisms. Lastly, soy isoflavone supplementation in postmenopausal women did not modulate ABCA1-specific macrophage cholesterol efflux but did increase production of plasma pre-β HDL levels, a subclass of HDL. Therefore, the impact of isoflavones on RCT and cardiovascular health needs to be further investigated. Taken as a whole, HDL-associated E2 fatty acyl esters from premenopausal women and soy phytoestrogen treatment in postmenopausal women may be important factors that increase the efficiency of RCT through cellular lipoprotein-related processes and may have direct implications on the cardiovascular health of women.

Trust, participation and health among ageing people : A cross-sectional cohort study of men and women born in 1926-30, 1936-40, and 1946-50 in the Lahti region, southern Finland

The purpose of the present study was to explore the associations between good self-rated health and economic and social factors in different regions among ageing people in the Päijät-Häme region in southern Finland. The data of this study were collected in 2002 as part of the research and development project Ikihyvä 2002 2012 (Good Ageing in Lahti region GOAL project). The baseline data set consisted of 2,815 participants born in 1926 30, 1936 40, and 1946 50. The response rate was 66 %. According to the previous studies, trust in other people and social participation as the main aspects of social capital are associated with self-rated health. In addition, socioeconomic position (SEP) and self-rated health are associated, but all SEP indicators do not have identical associations with health. However, there is a lack of knowledge of the health associations and regional differences with these factors, especially among ageing people. Regarding these questions, the present study gives new information. According to the results of this study, self-perceived adequacy of income was significantly associated with good self-rated health, especially in the urban areas. Similar associations were found in the rural areas, though education was also considered an important factor. Adequacy of income was an even stronger predictor of good health than the actual income. Women had better self-rated health than men only in the urban areas. The youngest respondents had quite equally better self-rated health than the others. Social participation and access to help when needed were associated with good self-rated health, especially in the urban area and the sparsely populated rural areas. The result was comparable in the rural population centres. The correlation of trust with self-rated health was significant in the urban area. High social capital was associated with good self-rated health in the urban area. The association was quite similar in the other areas, though it was statistically insignificant. High social capital consisted of co-existent high social participation and high trust. The association of traditionalism (low participation and high trust) with self-rated health was also substantial in the urban area. The associations of self-rated health with low social capital (low participation and low trust) and the miniaturisation of community (high participation and low trust) were less significant. From the forms of single participation, going to art exhibitions, theatre, movies, and concerts among women, and studying and self-development among men were positively related to self-rated health. Unexpectedly, among women, active participation in religious events and voluntary work was negatively associated with self-rated health. This may indicate a coping method with ill-health. As a whole, only minor variations in self-rated health were found between the areas. However, the significance of the factors associated with self-rated health varied according to the areas. Economic factors, especially self-perceived adequacy of income was strongly associated with good self-rated health. Also when adjusting for economic and several other background factors social factors (particularly high social capital, social participation, and access to help when needed) were associated with self-rated health. Thus, economic and social factors have a significant relation with the health of the ageing, and improving these factors may have favourable effects on health among ageing people.

Male eating disorders and related traits : Genetic epidemiological study in Finnish twins

The aim of this study was to deepen the understanding of eating disorders, body image dissatisfaction and related traits in males by examining the epidemiology and genetic epidemiology of these conditions in representative population-based twin samples. The sample of Study I included adolescent twins from FinnTwin12 cohorts born 1983 87 and assessed by a questionnaire at ages 14 y (N=2070 boys, N=2062 girls) and 17 y (N=1857 boys, N=1984 girls). Samples of Studies II-V consisted of young adult twins born 1974-79 from FinnTwin16 cohorts (Study II N=1245 men, Study III N=724 men, Study IV N=2122 men, Study V N=2426 women and N=1962 men), who were assessed by a questionnaire at the age 22-28 y. In addition, 49 men and 526 women were assessed by a diagnostic interview. The overall response rates for both twin cohorts in all studies were 80-90%. In boys, mainly genetic factors (82%, 95% confidence interval [CI] 72-92) explained the covariation of self-esteem between the ages 14 y and 17 y, whereas in girls, environmental factors (69%, 95% CI 43-93) were the largest contributors. Of young men, 30% experienced high muscle dissatisfaction, while 12% used or had used muscle building supplements and/or anabolic steroids on a regular basis. Muscle dissatisfaction exhibited a robust association with the indicators of mental distress and a genetic component (42%, 95% CI 23-59) for its liability in this population was found. The variation of muscle-building substance use was primarily explained by the environmental factors. The incidence rate of anorexia nervosa in males for the age of 10-24 y was 15.7 (95% CI 6.6-37.8) per 100 000 person-years, and its lifetime prevalence by the young adulthood was 0.24% (95% CI 0.03-0.44). All detected probands with anorexia nervosa had recovered from eating disorders, but suffered from substantial psychiatric comorbidity, which manifested also in their co-twins. Additionally, male co-twins of the probands displayed significant dissatisfaction with body musculature, a male-specific feature of body dysmorphic disorder. All probands were from twin pairs discordant for eating disorders. Of the five male probands with anorexia nervosa, only one was from an opposite-sex twin pair. Among women from the opposite-sex pairs, the prevalence of DSM-IV or broad anorexia nervosa was no significantly different compared to that of the women from monozygotic pairs or from dizygotic same-sex pairs. The prevalence of DSM-IV or broad bulimia nervosa did not differ in opposite- versus same-sex female twin individuals either. In both sexes, the overall profile of indicators on eating disorders was rather similar between individuals from opposite-sex and same-sex pairs. In adolescence, development of self-esteem was differently regulated in boys compared to girls: this finding may have far-reaching implications on the etiology of sex discrepancy of internalizing and externalizing disorders. In young men, muscle dissatisfaction and muscle building supplement/steroid use were relatively common. Muscle dissatisfaction was associated with marked psychological distress such as symptoms of depression and disordered eating. Both genetic and environmental factors explained muscle dissatisfaction in the population, but environmental factors appeared to best explain the use of muscle-building substances. In this study, anorexia nervosa in boys and young men from the general population was more common, transient and accompanied by more substantial co-morbidity than previously thought. Co-twins of the probands with anorexia nervosa displayed significant psychopathology such as male specific symptoms of body dysmorphic disorder, but none of them had had an eating disorder: taken together, these traits are suggestive for an endophenotype of anorexia nervosa in males. Little evidence was found on that the risk for anorexia nervosa, bulimia nervosa, disordered eating or body dissatisfaction were associated with twin zygosity. Thus, it is unlikely that in utero femininization, masculinization or postnatal socialization according to the sex of the co-twin have a major influence on the later development of eating disorders or related traits.
