Association of Red Meat Intake and Colorectal Cancer among East-Asians: A Systematic Review and Meta-analysis of Observational Studies Performed between 2011-2021.

BACKGROUND AND AIMS: Colorectal cancer has the third highest incidence and second highest mortality among all cancers worldwide. Although numerous studies investigating the associations between high red meat intake and risk of colorectal cancer have been published, the association between the intake of red meat and the risk of colorectal cancer in Asians remains unclear. We performed a systematic review and meta-analysis of cohort and case-control studies to estimate the association between red meat intake and colorectal cancer incidence rate between 2011-2021. METHOD: We searched PubMed database from 1 Jan 2011 to 21 July 2021. Prospective cohort studies and nested case-control studies that reported results on the association between red meat consumption and colorectal cancer were included in the meta-analysis. The outcome of interest was the association between the intake of red meat and the risk of colorectal cancer. We performed a meta-analysis to calculate the odds ratios (OR) with 95% confidence intervals (CI). RESULTS: A total of 5 studies enrolling 48,158 participants were included. The results showed no significant association between red meat intake and colorectal cancer risks (OR=1.38; 95%CI: 0.98-1.93). The aspect of the corresponding funnel plot suggested the presence of significant publication bias. Egger's test confirmed the significant asymmetry of the funnel plot (t = 9.3024, p = 0.0026). CONCLUSIONS: Contrary to many other meta-analyses, our study showed that intake of red meat was not associated with increased risk of colorectal cancer in East-Asians from China, Japan and South Korea. However, due to the limited number of included papers and the lack of confounders adjustments, our results warrant cautious interpretations.

Emotion dysregulation and symptoms of anxiety and depression in early adolescence: Bidirectional longitudinal associations and the antecedent role of parent-child attachment.

Difficulties in emotion regulation have been consistently associated with various psychological difficulties, including anxiety and depression; however, less is known about the directionality of this relationship, particularly in adolescents. In addition, early parent-child attachment quality has been closely linked to the development of emotion regulation. Previous studies have proposed an overarching model in attempt to describe the developmental trajectory of anxiety and depression from early attachment, albeit with several limitations that are discussed in this paper. This study adds to this field of research by investigating the longitudinal associations between emotion dysregulation (ED) and symptoms of anxiety and depression among 534 early adolescents in Singapore over three timepoints in a school year, and the antecedent role of attachment quality on individual differences on these variables. Bidirectional influences were found between ED and anxiety and depression symptoms, respectively, between T1 and T2, but not T2 and T3, at the between- and within-individual levels of analysis. Additionally, attachment anxiety and avoidance were both significantly predictive of individual differences in ED and for both psychological symptoms. The current findings provide preliminary evidence of a mutually reinforcing relationship between ED and symptoms of anxiety and depression in early adolescence, where attachment quality serves as a developmental antecedent that sets these longitudinal associations in motion.

Child shyness and peer likeability: The moderating role of pragmatics and vocabulary.

The association between shyness and children's likeability by peers was examined, with pragmatic difficulty and receptive and expressive vocabularies as moderators. Participants were 164 preschoolers (72 boys, 92 girls) between 52 and 79 months old in Singapore. A cross-informant methodology was used, with peers and teachers contributing to separate peer likeability ratings. The findings highlighted a conceptual distinction between peer- and teacher-rated likeability by peers. For the latter only, a 3-way interaction involving shyness, vocabulary, and pragmatic difficulty was found, indicating that for shy children with low vocabulary scores, those who experienced less pragmatic difficulty tended to be seen by teachers as more well-liked by peers than those with more pragmatic difficulty. This suggests that pragmatic skills may serve a protective function especially for shy children with poor vocabulary skills. Statement of contribution What is already known on this subject? Child shyness is related to poorer peer acceptance and social competence Expressive vocabulary and pragmatic competence each has a buffering effect for shy children What the present study adds? Shyness is related to poorer peer likeability as assessed by teachers Shyness is unrelated to peer likeability as assessed by same- or different-sex peers Pragmatic skills buffer the effects of teacher-rated shyness only for children with poor receptive and expressive vocabularies The buffering effect of language ability is shown in a multilingual educational context.

Measuring Maternal Sensitivity: Cultural Variations in the Measurement of Emotional Availability.

The validity of the Emotional Availability (EA) sensitivity scale was examined in Singapore. Participants were mainly from middle-class families of Chinese, Malay, Indian, and "Other" ethnic groups. Study 1 involved 30 mother-child dyads (children aged 4-6). Scores on EA sensitivity and the Maternal Behavior Q-set were highly correlated, suggesting convergent validity. In Study 2 (164 mother-child dyads), criterion validity was tested by the associations between EA sensitivity and children's vocabulary and likability by peers. Unlike findings from similar studies conducted in the United States, EA sensitivity was negatively correlated with children's likability by female peers, suggesting that measures developed in Western contexts may not be fully applicable locally, or that the meaning of sensitivity may vary across cultures.
