Secular trends in the incidence of anorexia nervosa: Integrative review of population-based studies

Abstract: Objective and Method: Aggregating across retrospective cohort samples, this integrative review synthesizes the findings of 12 cumulative incidence studies (45 hypotheses) on anorexia nervosa secular trends. Results: (1) The female/male anorexia incidence rate ratio was estimated to be 8.20, 18.46 versus 2.25 cases per 100,000 per year, p < .05; (2) female teenagers experienced anorexia at a rate fivefold greater than other women, 50.82 versus 10.37 incident cases per 100,000 per year, p < .001; (3) no secular trend or change in the incidence of anorexia was observed among teenagers, while a near threefold increase was observed over the past 40 years among women in their 20s and 30s, 6.28 (1950–1964) versus 17.70 (1980–1992) cases per 100,000 per year, p < .05; and (4) the two cohort characteristics of age, and the age by year interaction accounted for nearly two thirds of the variability among anorexia incidence estimates, R2 = .614, F(2,27) = 21.49, p < .001. After the two factors of age and the Age × Year interaction were accounted for, none of the other study characteristics, including study year(s), were found to be significantly associated with anorexia incidence, that is, a main effect of time was not observed. Discussion: The integrative evidence across the population-based epidemiologic studies covering 40 years in this field suggests strongly that, overall, the incidence of anorexia nervosa, particularly among those very young women at greatest risk of experiencing it, has not increased significantly. However, the risk does seem to have increased significantly among women in their 20s and 30s. © 1998 John Wiley & Sons, Inc. Int J Eat Disord 23: 347–352, 1998.

Phosphonium-borate zwitterions, anionic phosphines, and dianionic phosphonium-dialkoxides via tetrahydrofuran ring-opening reactions.

Abstract: Sterically demanding secondary phosphines and phosphides react with (THF)B(C6F5)3 (THF = tetrahydrofuran) to give the THF ring-opened compounds [R2PHC4H8OB(C6F5)3] and [Mes2PC4H8OB(C6F5)3Li(THF)2] (Mes = C6H2Me-2,4,6). These reactions also occur consecutively to give the double THF ring-opened compounds [Mes2P(C4H8OB(C6F5)3)2][Li(THF)4] and [t-Bu2P(C4H8OB(C6F5)3)2Li].

Genetic quality and offspring performance in Chinook salmon: implications for supportive breeding

Abstract: Each year salmon and other fishes are caught and used for supportive breeding programs that attempt to augment natural populations that are threatened with extinction. These programs typically mate individuals randomly and as such they overlook the importance of genetic quality to offspring fitness and ultimately to ensuring population health. Here, we use Chinook salmon (Oncorhynchus tshawytscha) and a fully crossed quantitative genetic breeding design to partition genetic variance in offspring performance (growth and survival) to additive and non-additive genetic effects as well as maternal effects. We show that these three effects contribute about equally to the variation in survival, but only non-additive genetic and maternal effects contribute to variation in growth. Some of the genetic effects could be assigned to variation at the class IIB locus of the major histocompatibility complex, but the maternal effects were not associated with egg size and we found no relationship between dam phenotypic measures and offspring survival or growth. We also found no relationship between sire sexually selected characters and offspring survival or growth, which is inconsistent with a “good genes” hypothesis. Finally, we show that incorporation of genetic quality into supportive breeding programs can increase offspring growth or survival by between 3% and 19% during the endogenous feeding stage alone, and projections to adulthood suggest that survivorship could be over four fold higher.
