This analysis draws on binational data from an ethnosurvey conducted in Guatemala and in the United States in Providence, Rhode Island, to develop a refinement of the weighting scheme that the Mexican Migration Project (MMP) uses. The alternative weighting procedure distinguishes between temporary and settled migrants by using a question on household location in the Guatemala questionnaire that is not used in the MMP. Demographic characteristics and integration experiences of the most recent U.S. trip are used to assess the composition and representativeness of the U.S. sample. Using a composite index of migrant integration to compare the impact of alternative U.S. sample weights on point estimates, I find that although the U.S. sample is broadly representative across a range of background characteristics, the MMP sample weighting procedure biases estimates of migrant integration downward.

Chronic Comorbidities

Background: Cardiovascular disease (CVD) has been the number one cause of death and disability in the US and globally for decades, and its comorbidity complicates the management of CVD. However, little is known about the secular trend of CVD comorbidities in national representative populations in the last 20 years. Methods: Prevalence of CVD and nine major chronic comorbidities was estimated using data from 1,324,214 adults aged 18 years and older in the National Health Interview Survey (NHIS) from 1997 through 2016, with age-standardized to the U.S. population in the year 2000. Results: CVD prevalence in the US adult population significantly declined in the past twenty years (from 6.6% in 1997 to 5.9% in 2016, P trend <0.01in Figure a). And such trend was shown in women and whites (P trend <0.01), but not in men and blacks (P trend >0.05). We ranked the nine major chronic comorbidities (high to low) in the CVD patients (Figure b.), including (1) hypertension, (2) respiratory conditions, (3) nervous system conditions, (4) digestive conditions, (5) diabetes, (6) cancer, (7) genitourinary conditions, (8) circulatory conditions, and (9) endocrine/nutritional/metabolic conditions. From 1997 to 2016, the prevalence of CVD comorbidities including hypertension (38.8% to 50.2%), digestive conditions (17.0% to 27.1%), diabetes (10.0% to 19.2%), cancer (9.4% to 12.8%), and genitourinary conditions (4.1% to 5.2%) continuingly increased (all P trend <0.01), while respiratory conditions declined (35.9% to 27.6%, P trend <0.01). Similar trends of CVD comorbidities were observed among subgroups stratified by gender or by race. Conclusions: CVD prevalence in the U.S. adults have declined significantly in the past two decades, but rates of CVD comorbidities including hypertension, digestive conditions, diabetes, cancer, and genitourinary conditions increased substantially.

Background: Obesity prevalence has been increasing while cardiometabolic mortality has been decreasing. The reasons for this paradox are not fully understood. Aim: To test the hypothesis that the prevalence of metabolically healthy obesity (MHO) in the U.S. adult population increases over time. Methods: The study included 16,459 participants of the National Health and Nutrition Examination Survey (NHANES) 1999-2014. MHO was defined as central obesity (waist circumference≥102 cm for men and ≥88 cm for women) without any of the following conditions: elevated levels of blood pressure (<125/85 mm Hg), glucose (<100 mg/dL), and triglycerides (<150 mm/dL), reduced levels of high-density lipoprotein cholesterol (≥40 mg/dL for men and ≥50 mg/dL for women), and any medication use for high cholesterol, hypertension, or diabetes. Results: The prevalence of central obesity increased from 45.17% in 1999-2000 to 56.72% in 2013-2014 (P=0.003). MHO prevalence increased from 4.95% in 1999-2000 to 8.92% in 2013-2014. Among those with central obesity, the proportion of MHO increased from 11.0% in 1999-2000 to 15.7% in 2013-2014. Female gender, a younger age, being Hispanic and non-Hispanic Black, and high education (some college or above) were associated with higher prevalence of MHO. Conclusions: While the prevalence of central obesity in the U.S. population has increased, the prevalence of MHO and the proportion of MHO among those who are centrally obese have also increased since 1999, which may partly contribute to the paradox between increased obesity prevalence and reduced cardiometabolic mortality.

Abstract Introduction: The MiniMed™ 670G system was FDA-approved in 2016 for adults and adolescents ≥14yrs, and in 2018 for children ages 7-13yrs with T1D. Since then, use of the system has grown to over 180,000 people in the U.S. The glycemic control benefits of real-world MiniMed™ 670G system Auto Mode use in the U.S. were assessed. Methods: System data (aggregated five-minute instances of sensor glucose [SG]) uploaded from March 2017 to July 2019 by individuals (N=118,737) with T1D and ≥7yrs of age who enabled Auto Mode were analyzed to determine the mean % of overall time spent &lt;54mg/dL/&lt;70mg/dL (TBR); between 70-180mg/dL (TIR); and &gt;180mg/dL/&gt;250mg/dL (TAR). The impact of Auto Mode was further assessed in a sub-group of individuals (N=51,254) with, at least, 7 days of SG data for both Auto Mode turned ON and turned OFF. The % of TIR, TBR and TAR, and the associated glucose management indicator (GMI) were evaluated for the overall OFF (2,524,570 days) and ON (6,308,806 days) periods, and across different age groups. Results: System data TIR was 71.3%; TBR was 0.4% and 1.9%, respectively; and TAR was 26.8% and 6.2%, respectively. User-wise data of Auto Mode OFF versus ON showed a mean of 70.3% of the time spent in Auto Mode, that TIR increased from 60.9% to 69.9%; and that both TBR and TAR decreased. For those 7-13yrs (N=1,417), TIR increased from 48.7% to 61.5%; TBR increased from 0.5% to 0.6% and from 2.0% to 2.2%, respectively; and TAR decreased from 49.3% to 36.3% and from 20.5% to 13.0%, respectively. For those 14-21yrs (N=4,194), TIR increased from 51.0% to 61.5%; TBR decreased from 0.7% to 0.6% and from 2.3% to 2.0%, respectively; and TAR decreased from 46.7% to 36.5% and from 18.5% to 12.5%, respectively. For those ≥22yrs (N=45,643), TIR increased from 62.2% to 70.9%; TBR decreased from 0.7% to 0.5% and from 2.6% to 1.9%, respectively; and TAR decreased from 35.2% to 27.3% and from 9.9% to 6.3%, respectively. The mean GMI decreased by 0.23% (overall), 0.48% (7-13yrs), 0.35% (14-21yrs), and 0.22% (≥22yrs), respectively, with Auto Mode ON versus OFF. Discussion: In over 6 million days of real-world MiniMed™ 670G system Auto Mode use in the U.S., TIR of a large pediatric and adult population with T1D improved by 9% compared to when Auto Mode was OFF, which was comparable to or exceeded the TIR observed in the smaller pivotal trials. These results further support outcomes of the pivotal trials and increased glycemic control with system use.
