Abstract In high-income countries, poverty is often associated with higher average body mass index (BMI). To account for this reverse gradient, deprivation theories posit that declining economic resources make it more difficult to maintain a healthy weight. By contrast, discrimination theories argue that anti-fat discrimination in hiring and marriage sorts heavier individuals into lower-income households. This study assesses competing predictions of these theories by examining how household income in representative samples from South Korea (2007–2014, N=20,823) and the US (1999–2014, N=6395) is related to BMI in two key contrasting groups: (1) currently-married and (2) never-married individuals. As expected by anti-fat discrimination in marriage, the reverse gradient is observed among currently-married women but not among never-married women in both countries. Also consistent with past studies no evidence was found for a reverse gradient among men. These findings are consistent with anti-fat discrimination in marriage as a key cause of the reverse gradient and raise serious challenges to deprivation accounts as well as explanations based on anti-fat discrimination in labour markets.

In high-income countries, poverty is often associated with higher average body mass index (BMI). To account for this reverse gradient, deprivation theories posit that declining economic resources make it more difficult to maintain a healthy weight. By contrast, discrimination theories argue that anti-fat discrimination in hiring and marriage sorts heavier individuals into lower-income households. We assess competing predictions of these theories by examining how household income in representative samples from South Korea (2007–2014, N=20,823) and the U.S. (1999–2014, N=6,395) is related to BMI in two key contrasting groups: (1) currently married and (2) never married individuals. Naïve analyses that aggregate these two groups reveal the well-established reverse gradient. Stratified analyses, on the other hand, reveal that the gradient only appears among currently married women, but not never-married women or men. Further analyses indicated that these differences in the gradient by marital status cannot be accounted for a number of alternative hypothesis based on differential employment or motivation to lose weight. Though consistent with predictions of anti-fat discrimination in marriage, these findings raise important challenges to deprivation theories of the reverse gradient.

Abstract Background The posterior thigh-based profunda artery perforator (PAP) flap has been an emerging option as a secondary choice in breast reconstructions. However, whether a PAP flap could consistently serve as the secondary option in slim patients has not been investigated. Methods Records of immediate unilateral breast reconstructions performed from May 2017 to June 2019 were reviewed. PAP flap breast reconstructions were compared with standard deep inferior epigastric perforator (DIEP) flap breast reconstructions, and were grouped into single or stacked PAP flaps for further analysis. Results Overall, 43 PAP flaps were performed to reconstruct 32 breasts. Eleven patients underwent stacked PAP flap reconstruction, while 17 patients underwent 21 single PAP flap reconstruction. The average body mass index (BMI) of the patients was 22.2 ± 0.5 kg/m2. The results were as follows: no total loss, one case of venous congestion (2.3%), two donor site wound dehiscence cases (4.7%), and one case of fat necrosis from partial flap loss (2.3%). When compared with 192 DIEP flap reconstructions, the final DIEP flap supplied 98.1 ± 1.7% of mastectomy weight, while the final PAP flap supplied 114.1 ± 6.2% of mastectomy weight (p < 0.005), demonstrating that PAP flaps can successfully supply final reconstruction volume. In a separate analysis, single PAP flaps successfully supplied 104.2% (84.2-144.4%) of mastectomy weights, while stacked PAP flaps supplied 103.7% (98.8-115.2%) of mastectomy weights. Conclusion In our series of PAP flap reconstructions performed in low-to-normal BMI patients, we found that PAP flaps, as single or stacked flaps, provide sufficient volume to reconstruct mastectomy defects.

This study analyzed partner volatility (new, old, revocation partners) and country-specific signal effects (United States (US), Taiwan, Japan, and South Korea) for Apple iPhone parts suppliers from 2007 to 2018. Mid- to long-term stock price movements were also analyzed to define trading patterns by investor type. The results using logit regression analysis revealed that new partners and revocation partners each have a signaling effect perceived as positive and negative information in the short term, and the excess returns by country showed a positive signaling effect in the order of the US, Taiwan, South Korea, and Japan. The findings also suggest that the change in the new partners’ stock price after the preannouncement of new products was useful investment information. Moreover, information asymmetry was found between individual investors, institutions, and foreigners. Results indicate that new partner selection in the smartphone market impacts corporate value and serves as useful investment information.

Limb Dominance

To test the null hypothesis that limb dominance (laterality) and side of complaint are not associated in a diverse population, nearly 400 patients (40% male, 60% female) of varying age and body size from three South Florida podiatric medical teaching facilities were surveyed in 1995-1996. Radiographs of feet were available for 15% of the patients, and the metatarsus adductus angle was measured on each x-ray. The typical patient was a women (median age, 49 years) of average body weight and average body-mass index. No statistical association was found between laterality and side of complaint in the broader sample, although a significant association did appear in the subsample of patients with bilateral x-rays. The prevalence of metatarsus adductus deformity (metatarsus adductus angle &gt; 15 degrees) among patients with x-rays was 62%. No sex-specific, age-specific, or body size-specific associations were found between handedness and metatarsus adductus deformity.
