White rice, brown rice and the risk of type 2 diabetes: a systematic review and meta-analysis

Objective Intake of white rice has been associated with elevated risk for type 2 diabetes (T2D), while studies on brown rice are conflicting. To inform dietary guidance, we synthesised the evidence on white rice and brown rice with T2D risk. Design Systematic review and meta-analysis. Data sources PubMed, EMBASE and Cochrane databases were searched through November 2021. Eligibility criteria Prospective cohort studies of white and brown rice intake on T2D risk (≥1 year), and randomised controlled trials (RCTs) comparing brown rice with white rice on cardiometabolic risk factors (≥2 weeks). Data extraction and synthesis Data were extracted by the primary reviewer and two additional reviewers. Meta-analyses were conducted using random-effects models and reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Risk of bias was assessed using the Newcastle Ottawa Scale for prospective cohort studies and the Cochrane Risk of Bias Tool for RCTs. Strength of the meta-evidence was assessed using NutriGrade. Results Nineteen articles were included: 8 cohort studies providing 18 estimates (white rice: 15 estimates, 25 956 cases, n=5 77 426; brown rice: 3 estimates, 10 507 cases, n=1 97 228) and 11 RCTs (n=1034). In cohort studies, white rice was associated with higher risk of T2D (pooled RR, 1.16; 95% CI: 1.02 to 1.32) comparing extreme categories. At intakes above ~300 g/day, a dose–response was observed (each 158 g/day serving was associated with 13% (11%–15%) higher risk of T2D). Intake of brown rice was associated with lower risk of T2D (pooled RR, 0.89; 95% CI: 0.81 to 0.97) comparing extreme categories. Each 50 g/day serving of brown rice was associated with 13% (6%–20%) lower risk of T2D. Cohort studies were considered to be of good or fair quality. RCTs showed an increase in high-density lipoprotein-cholesterol (0.06 mmol/L; 0.00 to 0.11 mmol/L) in the brown compared with white rice group. No other significant differences in risk factors were observed. The majority of RCTs were found to have some concern for risk of bias. Overall strength of the meta-evidence was moderate for cohort studies and moderate and low for RCTs. Conclusion Intake of white rice was associated with higher risk of T2D, while intake of brown rice was associated with lower risk. Findings from substitution trials on cardiometabolic risk factors were inconsistent

Emerging contexts of second-generation labour markets in the United States

In this paper I examine how local labour market contexts matter for the Hispanic adult children of immigrants in the United States. Specifically, I consider how these workers fit into ethnic divisions of labour in five metropolitan areas: the traditional immigrant cities of Los Angeles, New York and Chicago, and the newer immigrant gateways of Atlanta and Phoenix. I focus on the changing economies of these cities in the 1990s, and how industrial changes affect the jobs and relative wages available to immigrants and their adult children. I also examine the extent to which the adult children of immigrants are occupationally clustered in ‘immigrant jobs’. Intergenerational occupational shifts vary by metropolitan area, but are heavily gendered across all of them. I also discuss the interactions of other scales of context, since state and national-level legislation, local organising efforts and internal migration all shape the settings within which the children of immigrants come of ag

ADULTS READING ALOUD: A SURVEY OF CONTEMPORARY PRACTICES IN BRITAIN

While much is written about reading aloud to children, and as a teaching tool, far less is known about the oral reading that adults do at home, at work or in the community. This article presents the results of a national survey into whether, what, how and why adults across Britain may read aloud rather than in silence. Analysing data from 529 questionnaire responses, the article examines the frequency with which different text types are read aloud, the formations in which this is done – alone, with one other person or in a group – and the purposes of reading aloud and being read to, with attention to differences according to gender and age. Findings suggest that reading aloud happens in a number of different ways and for different purposes, across contexts and life domains, and that it has a significant relationship with aspects of the lifecourse and with identity formation and performance
