BACKGROUND It has been well-documented that Americans have shifted towards eating out more and cooking at home less. However, little is known about whether these trends have continued into the 21st century, and whether these trends are consistent amongst low-income individuals, who are increasingly the target of public health programs that promote home(More)
Age and portion size have been found to influence food intake in American children but have not been examined in an international context. This study evaluated the association between age and the effects of portion size on the food intake of kindergarteners in Kunming, China. Using a within-subjects crossover design in a classroom setting, 173 children in(More)
OBJECTIVES We examined the effects of state-level unemployment rates during the recession of 2008 on patterns of home food preparation and away-from-home (AFH) eating among low-income and minority populations. METHODS We analyzed pooled cross-sectional data on 118 635 adults aged 18 years or older who took part in the American Time Use Study. Multinomial(More)
To evaluate whether the dramatic rise in the cesarean section rate for breech presentation (from 22% in the decade 1963 to 1973 to 94% in 1978 and 1979) has been justified, 770 term breech deliveries at the Royal Victoria Hospital during the period 1963 to 1973 and during 1978 and 1979 have been reviewed. Neonatal outcome, as determined by one neonatologist(More)
The purpose of this study is to test the hypothesis that convenience for the physician plays a role in the rate of cesarean section performed because of dystocia. Three time periods were defined (night, 12 midnight to 7:59 AM; day, 8 AM to 5:59 PM; evening, 6 PM to 11:59 PM) based on the work commitments and daily routines of the obstetrician. Rates of(More)
Labor, delivery, and newborn course were studied in 621 pregnancies in which labor was electively induced at or after 39 weeks, and in 3,851 control pregnancies in which the onset of labor was spontaneous. Induced labors were not prolonged, nor was the duration of ruptured membranes. Fetal distress and birth asphyxia were not more frequent after induction,(More)
In a specific Obstetrics and Gynecological program, the program and certifying ITERs were evaluated for their measurement qualities. The internal consistency of the ITERs is supported. The tendency for high inter-item correlations suggest overall judgment of candidates may be influencing individual item rankings--particularly on the Program ITER.(More)
BACKGROUND Although body mass index (BMI) and waist circumference (WC) are correlated, the relationship between WC and BMI may have changed over time. OBJECTIVES To describe temporal trends in BMI and WC distributions and quantify the increase in WC at a given BMI over time. SUBJECTS/METHODS Data on adults aged 20-59 years from two waves (1993 and 2009)(More)
This paper addresses the need for diet assessment methods that capture the rapidly changing beverage consumption patterns in China. The objective of this study was to develop a 3-day smartphone-assisted 24-hour recall to improve the quantification of beverage intake amongst young Chinese adults (n=110) and validate, in a small subset (n=34), the extent to(More)
