Investigation of the relationship between infant temperament and later body composition.

OBJECTIVE: To investigate the ability of maternally-rated infant temperament to predict fatness and activity patterns in early childhood. DESIGN: Longitudinal investigation of infants studied at 12 weeks and followed up at 2-3.5 y of age. SUBJECTS: Thirty healthy full-term infants from the general population. MEASUREMENTS: Body composition, behavioural activity and temperament at 12 weeks; anthropometry, body composition, diet and behavioural activity at follow-up. RESULTS: Infant temperament predicted later behaviour and fatness. Easily soothable infants had leaner childhood skinfold thicknesses (P < 0.02) and were more active in childhood (P < 0.025). Infant distress was also related to childhood diet composition. CONCLUSIONS: Infant temperament can predict later body composition and behaviour. Both energy intake and energy expenditure may be mechanisms by which the relationship develops.

The impact of socioeconomic status on health functioning as assessed by the SF-36 questionnaire: the Whitehall II Study.

OBJECTIVES: This study measured the association between socioeconomic status and the eight scale scores of the Medical Outcomes Study short form 36 (SF-36) general health survey in the Whitehall II study of British civil servants. It also assessed, for the physical functioning scale, whether this association was independent of disease. METHODS: A questionnaire containing the SF-36 was administered at the third phase of the study to 5766 men and 2589 women aged 39 through 63 years. Socioeconomic status was measured by means of six levels of employment grades. RESULTS: There were significant improvements with age in general mental health, role-emotional, vitality, and social functioning scale scores. In men, all the scales except vitality showed significant age-adjusted gradients across the employment grades (lower grades, worse health). Among women, a similar relationship was found for the physical functioning, pain, and social functioning scales. For physical functioning, the effect of grade was found in those with and without disease. CONCLUSIONS: Low socioeconomic status was associated with poor health functioning, and the effect sizes were comparable to those for some clinical conditions. For physical functioning, this association may act both via and independently of disease.

Is delayed surgery really better for congenital diaphragmatic hernia?: a prospective randomized clinical trial.

Delayed surgery has become widely accepted in the management of congenital diaphragmatic hernia after comparing outcomes only with historical retrospective controls. It was the aim of this study to compare early and delayed hernia repair in a randomized prospective clinical trial. Fifty-four infants were randomized to receive either early repair (within 4 hours of admission) or delayed repair (more than 24 hours after birth). The survival rate was higher for the delayed group (57% v 46%), but the difference was not significant (difference: -11; 95% confidence limits: -37.5, 15.5). There were no significant differences between the two groups with respect to length of hospital stay, ventilator dependency, or survival time. Recorded preoperative risk factors were similar for the two groups. Eight infants in the delayed repair group died without having undergone surgery. The optimum time for surgery still needs clarification.

Human T lymphotropic virus type I-associated myelopathy. A report of 10 patients born in the United States.

Human T lymphotropic virus type I (HTLV-I)-associated myelopathy (HAM) (tropical spastic paraparesis/HAM) has rarely been reported in the United States. We present 10 well-documented cases with positive Western immunoblot test results and polymerase chain reactions for HTLV-I. The clinical and laboratory features of these American-born patients resemble those previously reported series of tropical spastic paraparesis and HAM from the Caribbean and Japan, but important differences were observed. In our study there were equal numbers of whites and blacks and of men and women. Age at onset was younger than that reported from the Caribbean and Japan. Rate of progression to paraparesis varied but was more rapid than previously reported. Half were transfusion recipients but six had multiple sexual partners, with one regularly interacting with prostitutes and reporting a history of drug abuse. Although more rapid progression was seen in the transfusion recipients, this did not explain the earlier age of onset in this group of patients. The HTLV-I, and the associated myelopathy, are endemic in Florida, suggesting that immigration from, and proximity, to the Caribbean basin are contributing risk factors.
