Personality characteristics were assessed in women who had physically and, in the majority, psychologically recovered from restricting anorexia nervosa at an 8- to 10-year follow-up. Personality dimensions were evaluated using the Multidimensional Personality Questionnaire, the California Personality Inventory, and the Reid-Ware Scale. Women who had recovered from anorexia nervosa rated higher on risk avoidance, displayed greater restraint in emotional expression and initiative, and showed greater conformance to authority than age-matched normal women. On comparison with their sisters, the recovered women reported a greater degree of self- and impulse control and less enterprise and spontaneity; sisters, however, endorsed equally high moral standards. The differences in personality characteristics remained significant after statistically controlling for depressive symptoms and eating behavior. The results suggest that a temperamental disposition toward emotional and behavioral restraint combined with a strong sense for traditional values may be psychological risk factors for the development of the restricting type of anorexia nervosa.

The findings provide evidence that the length of prenatal SSRI antidepressant use can affect neonatal adjustment and can have an effect on psychomotor test scores in infancy. Importantly, the children's mental development and motor function by neurological examination were within the normal range. Timing of exposure to SSRIs during susceptible periods of fetal development and variations in the severity of maternal depression may have contributed to the associations.

Clinical reports consistently comment on high physical activity for anorexia nervosa patients but provide few quantitative measurements. To assess activity, total daily energy expenditure (TDEE) by doubly labeled water, basal metabolic rate (BMR), and thermic effect of meals (TEM) were measured in six female outpatients with anorexia nervosa (67% of ideal body weight) and age-, sex-, and height-matched to six control subjects. Anorexia nervosa patients expended more energy as physical activity than did control subjects [0.084 +/- 0.012 vs 0.044 +/- 0.008 MJ/kg body wt, respectively (20.1 +/- 3.0 vs 10.5 +/- 1.9 kcal/kg body wt, respectively), P less than 0.04], although they had a lower BMR [4.17 +/- 0.37 vs 5.52 +/- 0.15 MJ/d, respectively (997 +/- 89 vs 1319 +/- 37 kcal/d, respectively), P less than 0.01]. TDEE and TEM were similar in both groups. There was a reduction in serum triiodothyronine (T3; 1.20 +/- 0.15 vs 2.04 +/- 0.13 nmol/L, respectively; P less than 0.003) and a slight reduction in serum thyroxine (T4); reverse T3, thyrotropin, free T4, serum cortisol, and adrenocorticotropin values were normal. BMR correlated with total body weight and fat-free mass. These results provide quantitative evidence for increased physical activity in anorexia nervosa despite profound underweight and hypometabolism.

SynopsisThis research was aimed at studying the rate of action of tricyclic drugs in depressive disorders, specifying the behavioural effects associated with recovery, and predicting clinical response. The research design involved comparison of a recovered group with a group treated for the equivalent four weeks, who showed minimal to no response. The findings indicated significant differences in baseline characteristics between responders and non-responders. Further, the drugs were found to act early in the responders, within the first week of treatment. Specific changes at one week which distinguished responder and non-responder groups occurred in the disturbed affects, and in cognitive functioning. Improvements also occurred in somatic symptoms, but these latter changes were general and not associated with later recovery. At 2½ weeks, all facets of the depressed condition showed positive change in the responders. Implications of the results for assessing rate of tricyclic drug actions, their effects on the interaction of affect and neurochemistry, and the practical application of the results for the clinical situation, are discussed.
