Secular changes in physical growth and obesity among southwestern American Indian children over four decades.

ABSTRACT: BACKGROUND AND OBJECTIVES:Most studies describing childhood obesity in the United States are based on cross-sectional surveys and do not include substantial numbers of American Indians (AI). Secular trends in height and weight reflect general health status. This study describes weight trends and transitions among AI children over a 43-year period. METHODS:Anthropometric data were obtained from a prospective study conducted in a southwestern US AI population (1965 through 2007). For cross-sectional analysis, 12?377 observations were available from 6529 children across four birth cohorts (1955-1964, 1965-1974, 1975-1984, 1985-1994). Participants were stratified into three age groups: pre- (5-9?years), early (10-13) and late (14-17) adolescence. Longitudinal analyses included 1737 children with one exam in each age group. RESULTS:In early and late adolescence, weight increased across birth cohorts. Prevalence of obesity among pre-adolescents was 17.5% (95% CI, 15.1%-19.9%) in the 1955-1964 cohort and 33.7% (95% CI, 30.1%-36.4%) in the 1985-1994 cohort. 74% of children overweight in pre-adolescence in the 1985-1994 cohort became obese by late adolescence; in the 1955-1964 cohort, only 43% made this transition. CONCLUSIONS:This study describes the rising prevalence of childhood obesity. Children obese in pre-adolescence remained obese in late adolescence, stressing the need for early intervention.

Project description:ObjectiveAs the number of female medical students and surgical residents increases, the increasing number of female academic surgeons has been disproportionate. The purpose of this brief report is to evaluate the AAMC data from 1969 to 2018 to compare the level of female academic faculty representation for surgical specialties over the past four decades.DesignThe number of women as a percentage of the total surgeons per year were recorded for each year from 1969-2018, the most recent year available. Descriptive statistics were performed. Poisson regression examined the percentage of women in each field as the outcome of interest with the year and specialty (using general surgery as a reference) as two predictor variables.SettingData from the American Association of Medical Colleges (AAMC).ParticipantsAll full-time academic faculty physicians in the specialties of obstetrics and gynecology (OB/GYN), general surgery, ophthalmology, otolaryngology (ENT), plastic surgery, plastic surgery, urology, neurosurgery, orthopaedic surgery and cardiothoracic surgery as per AAMC records.ResultsThe percentage of women in surgery for all specialties evaluated increased from 1969 to 2018 (OR 1.04, p<0.001). Compared with general surgery, the rate of yearly percentage change increased more slowly in neurosurgery (OR 0.84; P = .004), orthopaedic surgery (OR 0.82; P = .002), urology (OR 0.59; P < .001), and cardiothoracic surgery (OR 0.38; P < .001). There was no significant difference in the rate of yearly percentage change for plastic surgery (OR 1.01; P = .840). The rate of yearly percentage change increased more rapidly in OB/GYN (OR 2.86; P < .001), ophthalmology (OR 1.79; P < .001) and ENT (OR 1.70; P < .001).ConclusionsRepresentation of women in academic surgery is increasing overall but is increasing more slowly in orthopaedic surgery, neurosurgery, cardiothoracic surgery and urology compared with that in general surgery. These data may be used to inform and further the discussion of how mentorship and sponsorship of female students and trainees interested in surgical careers may improve gender equity in the future.

Project description:ObjectivesTo investigate the hypothesis that junior doctors' examination skills are deteriorating by assessing the medical admission note examination record.DesignRetrospective study of the admission record.SettingTertiary care hospital.MethodsThe admission records of 266 patients admitted to Wellington hospital between 1975 and 2011 were analysed, according to the total number of physical examination observations (PEOtot), examination of the relevant system pertaining to the presenting complaint (RelSystem) and the number of body systems examined (Nsystems). Subgroup analysis proceeded according to admission year, level of experience of the admitting doctor (registrar, house surgeon (HS) and trainee intern (TI)) and medical versus surgical admission notes. Further analysis investigated the trend over time in documentation with respect to cardiac murmurs, palpable liver, palpable spleen, carotid bruit, heart rate, funduscopy and apex beat location and character.ResultsPEOtot declined by 34% from 1975 to 2011. Surgical admission notes had 21% fewer observations than medical notes. RelSystem occurred in 94% of admissions, with no decline over time. Medical notes documented this more frequently than surgical notes (98% and 86%, respectively). There were no differences between registrars and HS, except for the 2010s subgroup (97% and 65%, respectively). Nsystems declined over the study period. Medical admission notes documented more body systems than surgical notes. There were no differences between registrars, HSs and TIs. Fewer examinations were performed for palpable liver, palpable spleen, cardiac murmur and apex beat location and character over the study period. There was no temporal change in the positive findings of these observations or heart rate rounding.ConclusionsThere has been a decline in the admission record at Wellington hospital between 1975 and 2011, implying a deterioration in local doctors' physical examination skills. Measures to counter this trend are discussed.
