Psychometric properties of a revised Danish translation of the international outcome inventory for hearing aids (IOI-HA).

Objective: The original Danish translation of the international outcome inventory for hearing aids (IOI-HA) proved problematic as the wording of item 5 was not semantically clear, rendering the questionnaire internally inconsistent. The objective of this study was to examine data collected with a revised Danish translation of the IOI-HA in order to: (1) evaluate the effect of the revision, and (2) to examine if the psychometric properties of the revised translation of the IOI-HA are equivalent to those of previously validated translations.

Design: Psychometric properties were evaluated performing inter-item correlation analysis, principal component analysis, and item-total correlation.

A randomized trial of the effects of dietary counseling on gestational weight gain and glucose metabolism in obese pregnant women.

Objective: Can gestational weight gain in obese women be restricted by 10-h dietary consultations and does this restriction impact the pregnancy-induced changes in glucose metabolism?

Design: A randomized controlled trial with or without restriction of gestational weight gain to 6-7 kg by ten 1-h dietary consultations.

Subjects: Fifty nondiabetic nonsmoking Caucasian obese pregnant women were randomized into intervention group (n=23, 28+/-4 years, prepregnant body mass index (BMI) 35+/-4 kg m(-2)) or control group (n=27, 30+/-5 years, prepregnant BMI 35+/-3 kg m(-2)).

Measurements: The weight development was measured at inclusion (15 weeks), at 27 weeks, and 36 weeks of gestation.

Danish obstetricians' personal preference and general attitude to elective cesarean section on maternal request: a nation-wide postal survey.

Objective: To assess Danish obstetricians' and gynecologists' personal preference and general attitude towards elective cesarean section on maternal request in uncomplicated single cephalic pregnancies at term.

Design: Nation-wide anonymous postal questionnaire.

Population: Four hundred and fifty-five obstetricians and gynecologists identified in the records of the Danish Society of Obstetrics and Gynecology from January 2000.

A longitudinal study of intrauterine growth and the placental growth hormone (GH)-insulin-like growth factor I axis in maternal circulation: association between placental GH and fetal growth.

The aim of the study was 1) to evaluate the association of maternal serum levels of placental GH and IGF-I with fetal growth, and 2) to establish reference data for placental GH, IGF-I, and IGF-binding protein-3 (IGFBP-3) in normal pregnancies based on longitudinal measurements. A prospective longitudinal study of 89 normal pregnant women was conducted. The women had, on the average, seven blood samples taken and three ultrasound examinations performed.
