RESUMEN
RATIONALE & OBJECTIVE: Ultraprocessed foods are widely consumed in the United States and are associated with cardiovascular disease (CVD), mortality, and kidney function decline in the general population. We investigated associations between ultraprocessed food intake and chronic kidney disease (CKD) progression, all-cause mortality, and incident CVD in adults with chronic kidney disease (CKD). STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: Chronic Renal Insufficiency Cohort Study participants who completed baseline dietary questionnaires. EXPOSURE: Ultraprocessed food intake (in servings per day) classified according to the NOVA system. OUTCOMES: CKD progression (≥50% decrease in estimated glomerular filtration rate [eGFR] or initiation of kidney replacement therapy), all-cause mortality, and incident CVD (myocardial infarction, congestive heart failure, or stroke). ANALYTICAL APPROACH: Cox proportional hazards models adjusted for demographic, lifestyle, and health covariates. RESULTS: There were 1,047 CKD progression events observed during a median follow-up of 7 years. Greater ultraprocessed food intake was associated with higher risk of CKD progression (tertile 3 vs tertile 1, HR, 1.22; 95% CI, 1.04-1.42; P=0.01 for trend). The association differed by baseline kidney function, such that greater intake was associated with higher risk among people with CKD stages 1/2 (eGFR≥60mL/min/1.73m2; tertile 3 vs tertile 1, HR, 2.61; 95% CI, 1.32-5.18) but not stages 3a-5 (eGFR<60mL/min/1.73m2; P=0.003 for interaction). There were 1,104 deaths observed during a median follow-up of 14 years. Greater ultraprocessed food intake was associated with higher risk of mortality (tertile 3 vs tertile 1, HR, 1.21; 95% CI, 1.04-1.40; P=0.004 for trend). LIMITATIONS: Self-reported diet. CONCLUSIONS: Greater ultraprocessed food intake may be associated with CKD progression in earlier stages of CKD and is associated with higher risk of all-cause mortality in adults with CKD. PLAIN LANGUAGE SUMMARY: Ultraprocessed foods are industrial formulations produced using ingredients and processes that are not commonly used in culinary preparations and contain few, if any, intact unprocessed foods. Ultraprocessed foods are widely consumed in the United States, and high intakes of such foods have been linked to cardiovascular disease, kidney disease, and mortality in the general population. In this study, we found that greater intake of ultraprocessed foods was associated with higher risk of kidney disease progression and mortality in adults with chronic kidney disease. Our findings suggest that patients with kidney disease may benefit from greater consumption of fresh, whole, and homemade or hand-prepared foods and fewer highly processed foods.

Evidence suggests women in sub-Saharan Africa may be more likely to experience intimate partner violence (IPV) than women anywhere else in the world. Data was obtained from women (n = 29,444) who completed the Demographic Health Survey's (DHS) domestic violence module in seven countries in sub-Saharan Africa countries between 2011 and 2015. Women who reported controlling behavior by a spouse/partner were more likely to have experienced less severe lifetime physical violence (adjusted odds ratio (AOR) 3.02, 95% confidence interval (CI) 2.63, 3.47) and severe violence (AOR 4.27, 95% CI 3.32, 5.49). Partner's controlling behavior may increase the likelihood of experiencing both less severe and severe lifetime physical violence.

INTRODUCTION: It is unclear whether changes in beverage price and sales after beverage tax implementation can be sustained long term. This study aims to quantify the changes in beverage prices and sales in large retailers 2 years after the implementation of the 1.5 cents per ounce Philadelphia beverage tax. METHODS: Data on price and volume sales of beverages and potential food substitutes were collected from 109 supermarkets, 45 mass merchandizers, and 350 pharmacies in Philadelphia, Baltimore (control), and Pennsylvania ZIP codes bordering Philadelphia (to investigate potential cross-border shopping for tax avoidance). Difference-in-differences analyses compared beverage prices and volume sales in the year before tax implementation (2016) to 2 years after (2018). Data were analyzed in 2020-2021. RESULTS: Difference-in-differences analyses found that after tax implementation, taxed beverage prices in Philadelphia increased by 1.02 cents per ounce (95% CI=0.94, 1.11; 68% pass through), and taxed beverage volume sales in stores decreased by 50% (95% CI=36%, 61%). After accounting for cross-border shopping, taxed beverage volume sales decreased in Philadelphia by 35% in 2018. Volume sales of nontaxed beverages did not change after tax implementation (difference-in-differences=4%, 95% CI= -3%, 12%). Volume sales of nontaxed beverage concentrates increased on average by 34% (95% CI=19%, 51%), but there was no evidence of substitution to high-calorie foods. CONCLUSIONS: There was a large reduction in taxed beverage volume sales 2 years after Philadelphia tax implementation, even after accounting for cross-border shopping. Increases in nontaxed beverage concentrate sales likely partially offset this decline, but there was no evidence of post-tax food substitution.

Intimate partner violence (IPV), commonly accompanied by controlling behavior, is a serious public health concern in sub-Saharan Africa. Data from women (n = 37,115) aged 15 to 49 years who completed the Demographic Health Survey's (DHS) domestic violence module in eight countries in sub-Saharan Africa (Cameroon, Democratic Republic of the Congo [DRC], Côte d'Ivoire, Namibia, Rwanda, Sierra Leone, Togo, and Zambia) between 2011 and 2015 were obtained. DHS questions assessed lifetime physical, emotional, and sexual violence (ever vs. never). Controlling behavior was measured by a revised Conflict Tactics Scale. Multivariate logistic regression examined the association between controlling behavior and IPV adjusting for all covariates, including age, education, marital status, wealth, urban/rural setting, and occupation. An interaction term was included to evaluate the consistency of effect estimates across countries. In all, 45.60% of women reported experiencing one or more forms of IPV (physical, sexual, or emotional violence) in their lifetime, ranging from 31.16% in Côte d'Ivoire to 57.37% in Cameroon. Women who reported controlling behavior by a spouse/partner were more likely to have experienced lifetime physical (adjusted odds ratio [AOR] = 3.57, 95% confidence interval [CI] = [3.31, 3.85], sexual (AOR = 3.98, CI = [3.47, 4.57]) or emotional (AOR = 3.52, CI = [3.22, 3.85]) violence than women who did not report controlling behavior. Women who reported controlling behavior were also more likely to have experienced one (AOR = 2.57, CI = [2.36, 2.81]) or two/three types (AOR = 5.34, CI = [4.80, 5.94]) of violence. AORs did not significantly differ across countries. Further research is needed to evaluate whether policies, programs, and education aimed at preventing or modifying controlling behavior may reduce IPV.
