Measures of initiation and progression to increased smoking among current menthol compared to non-menthol cigarette smokers based on data from four U.S. government surveys

There are no large-scale, carefully designed cohort studies that provide evidence on whether menthol cigarette use is associated with a differential risk of initiating and/or progressing to increased smoking. However, questions of whether current menthol cigarette smokers initiated smoking at a younger age or are more likely to have transitioned from non-daily to daily cigarette use compared to non-menthol smokers can be addressed using cross-sectional data from U.S. government surveys. Analyses of nationally representative samples of adult and youth smokers indicate that current menthol cigarette use is not associated with an earlier age of having initiated smoking or greater likelihood of being a daily versus non-daily smoker. Some surveys likewise provide information on cigarette type preference (menthol versus non-menthol) among youth at different stages or trajectories of smoking, based on number of days smoked during the past month and/or cigarettes smoked per day. Prevalence of menthol cigarette use does not appear to differ among new, less experienced youth smokers compared to established youth smokers. While there are limitations with regard to inferences that can be drawn from cross-sectional analyses, these data do not suggest any adverse effects for menthol cigarettes on measures of initiation and progression to increased smoking.     

National trends in school victimization among Asian American adolescents

The “model minority” perception of Asian American students often ignores the academic and social challenges that many face in schools. One area that has received less attention is the school victimization experiences of Asian American adolescents. While some qualitative researchers have explored factors contributing to school victimization in recent years, missing in the literature is the scope of these incidents among Asian Americans. This paper contributes to this literature by (1) examining national trends in the victimization of Asian American adolescents in schools over the last decade and (2) investigating how victimization varies according to their gender, socioeconomic status, and achievement levels. The results show that although Asian American adolescents are consistently less likely to be bullied relative to other students, they are more likely to report experiences of racial discrimination. Victimization incidents for Asian Americans also differ by gender and academic achievement levels.     

Which dietary diversity indicator is best to assess micronutrient adequacy in children 1 to 9 y?

ObjectivesThe aim of this study was to determine the best dietary diversity indicator to measure dietary diversity and micronutrient adequacy in children.MethodsA national representative cross-sectional survey of children ages 1 to 9 y (N = 2,200) was undertaken in all ethnic groups in South Africa. A 24-h recall was done with the mother or caregiver of each child. A dietary diversity score (DDS), the number of food groups consumed at least once in a period of 24 h, was calculated for each child in accordance with 6-, 9-, 13-, and 21-food group (G) indicators and compared with a mean adequacy ratio (MAR). The nutrient adequacy ratio (NAR) was calculated for 11 micronutrients by comparing the distributions of estimated intakes with the Estimated Average Requirements for that micronutrient. The MAR was the average of all NARs. Correlations were done between MAR and DDS and sensitivity and specificity calculated for each group indicator.ResultsPearson’s correlations between food group indicators and MAR indicate that r values were all highly significant (P < 0.0001). There were no consistent or large differences found between the different group indicators although G13 and G21 appeared to be marginally better. Sensitivity and specificity values in the current study lay between DDS of 3 and 5, suggesting one of these as the best indication of (low) micronutrient adequacy.ConclusionsOverall results seem to indicate that any of the four G indicators can be used in dietary assessment studies on children, with G13 and G21 being marginally better. A cut-off DDS of 4 and 5, respectively, appear best.     

美国马里兰州医院支付体系及其启示

自1977年以来,美国马里兰州医院体系一直执行统一的收费标准,称之为All-payer system。该支付体系最大特点是:对于在同一医院就诊的患者,无论其是否参与任何形式的保险,都按照统一的支付标准向医院支付费用。其优点在于通过政府主导方式对医院体系面临的市场失灵的风险以及医院承担的重要社会责任需消耗的成本进行补偿,有效控制医院成本并促进效率提高。     

Devaluation,Loss, and Rage: A Postscript to Urban African American Youth with Substance Abuse

This article explores and discusses the sociocultural dynamics underpinning urban African American youths' use and misuse of substances and its connection to the invisible wounds of race-related trauma. A racially-sensitive framework is discussed as an intervention approach designed to address the special needs of urban Africa American adolescents maligned by, and suffering from, the complex interplay of substance misuse and rage.     

Strategies to Resist Drug Offers Among Urban American Indian Youth of the Southwest: An Enumeration,Classification, and Analysis by Substance and Offeror

This study explores the drug resistance strategies of urban American Indian adolescents when they encounter people offering them alcohol, cigarettes, and marijuana. Data were collected in 2005 from 11 female and 9 male adolescents who self-identified as American Indian and attended two urban middle schools in the southwestern United States. In two focus groups—one at each school site—the youth described their reactions to 25 hypothetical substance offer scenarios drawn from real-life narratives of similar youth. Qualitative analysis of their 552 responses to the scenarios generated 14 categories. Half of the responses were strategies reported most often by nonnative youth (refuse, explain, leave, and avoid). Using ecodevelopmental theory, the responses were analyzed for indications of culturally specific ways of resisting substance offers, such as variation by specific substance and relationship to the person offering. Study limitations are noted along with suggestive implications for future research on culturally appropriate prevention approaches for urban American Indian youth.
