Prevalence of overweight and obesity among children and adolescents with intellectual disabilities: a systematic review and meta-analysis.

Although there have been numerous studies examining the prevalence of overweight and obesity among children and adolescents with intellectual disabilities, they have not yet been integrated and synthesized through a systematic quantitative review process. The purpose of this systematic review and meta-analysis was to determine: (i) the prevalence of overweight/obesity among children and adolescents with intellectual disabilities; (ii) the sources of heterogeneity in studies reporting the prevalence of overweight/obesity in this population; and (iii) the risk of overweight/obesity in this population compared with their typically developing peers. A systematic literature search was performed and 16 studies, published between 1985 and 2015, met the inclusion criteria. The resulting pooled prevalence estimates for overweight, overweight-obesity and obesity were respectively: (i) 15%, 30%, and 13%, in children; and (ii) 18%, 33%, and 15% in adolescents. Subgroup analyses showed significant variations in the pooled prevalence estimates as a function of geographical region, recruitment setting, additional diagnoses, and norms used to define overweight or obesity. The findings also showed adolescents with intellectual disabilities to be respectively 1.54 and 1.80 times more at risk of overweight-obesity and obesity than typically developing adolescents. Unfortunately, no such comparison is available for children. © 2016 World Obesity.

[Fear of childbirth among nulliparous women: Relations with pain during delivery, post-traumatic stress symptoms, and postpartum depressive symptoms]. / La peur de l'accouchement chez des nullipares: lien avec la douleur lors de l'accouchement, les symptômes de stress post-traumatique et les symptômes dépressifs post-partum.

OBJECTIVE: Fear of childbirth is common in women who are pregnant with their first child and is associated with important consequences such as abortions and miscarriages. Twenty percent of nulliparous women seem to exhibit a mild or moderate fear, while 6% present an excessive and irrational fear known as tocophobia. Tocophobia is suggested to be associated with many negative consequences such as postpartum depression (PPD) and Post-traumatic stress (PTS). However, there is little empirical evidence to support these relationships. Recently, Fairbrother and Woody (2007) did not observe a link between the fear of childbirth and symptoms of PPD and PTS in nulliparous women. Some results, near the significance level, could be explained by a lack of statistical power. The present study focused on the link between the fear of childbirth and the process of delivery, the perception of pain, PPD and PTS. More specifically, it aimed to test three hypotheses: (i) fear of childbirth will be linked to the process of delivery, especially regarding the perception of pain, the use of anaesthesia and the use of Caesarean section; (ii) a high level of fear of childbirth will be associated with more negative postpartum consequences (namely PPD/PTS symptoms); (iii) the process of delivery and pain will also be related to post-delivery symptoms. Mediation effects were tested. METHOD: Data from a longitudinal study were used to meet the hypotheses. A total of 176 nulliparous pregnant women responded to questionnaires at two time measurements (during pregnancy and at 5weeks postpartum). RESULTS: Fear of childbirth is related to the perception of pain at birth among women delivering vaginally, in the absence of anaesthesia. It is also linked to symptoms of PPD and PTS, regardless of whether or not anaesthesia was used. Fear of childbirth also appears to be strongly associated to symptoms of PTS in women who have experienced an unplanned caesarean section. Thus, symptoms of postpartum PTS could play a mediating role in the link between fear of childbirth and PPD. CONCLUSIONS: These results support the relevance of taking into account the fear of childbirth and perception of pain in connection with symptoms of PTS and PPD in nulliparous women. The unplanned caesarean section (including emergency caesarean) also appears to be important in the study of the relationship between fear and symptoms of PTS. Fear of childbirth could render the experience of childbearing more negative and predispose to PTS and PPD. Enabling psychological vulnerabilities could also be an interesting avenue for understanding these links. Limitations are discussed.

Prevalence and sport-related predictors of disturbed eating attitudes and behaviors: Moderating effects of sex and age.

Very few studies examined the prevalence and sport-related predictors of disturbed eating attitudes and behaviors (DEABs) among adolescents involved in sport practice, and their results are mixed and inconclusive. These inconsistencies are most likely due to their methodological heterogeneity and to the fact that none of these studies took into consideration the potentially relevant characteristics of the sport practice context. This study attempts to answer this limitation among French adolescents not involved or involved in various sports contexts defined based on their organization, leanness-centration, and competitive level. Participants were 335 adolescents involved in sport practice, and 435 adolescents not involved in any form of regular sport practice. The DEABs were measured using the Eating Attitudes Test-26. Global results do not showed any significant association between the status of the participants and DEAB. However, these results drastically changed when we considered the potential moderating role of sex and age on these relations. Indeed, sports involvement in general, and involvement in leanness and competitive sports were found to exert sex- and age-differentiated effects on the risks of presenting clinically significant levels of DEAB. This study suggests the importance of monitoring, preventive, and early intervention mechanisms within the context of practice, particularly for adolescent girls.

[French adaptation and validation of a scale measuring the fear of childbirth]. / Évaluation de la peur de l'accouchement. Validation et adaptation française d'une échelle mesurant la peur de l'accouchement.

OBJECTIVES: The fear of childbirth, a central aspect of tokophobia, recently started to capture the attention of the scientific community as a potential determinant of obstetric and post-natal complications. However, studies on this subject are still few and this can be partly explained by the lack of validated instruments, especially in French. This paper presents the results from two studies designed to develop and evaluate the psychometric properties of a French version of the Traumatic Event Scale (TES), adapted to assess fear of childbirth (Söderquist et al., 2004 [21]). METHOD: The first study presents details regarding the development of this scale and checks the quality of the resulting items as well as their internal consistency, convergent validity and factorial validity. This study relied on a sample of 65 mothers with at least one child under the age of 36 months. In the second study, the psychometric properties of the instrument developed in Study 1 were tested more systematically on a sample of 204 women who were at the time experiencing their first pregnancy. RESULTS AND CONCLUSION: The results from the first study show adequate psychometric properties, strong correlations with measurements assessing worry, and support a five factor model. Results from this second study replicated the results from the first one on the basis of confirmatory factor analyses. Findings presented in these studies confirm that this instrument presents very good psychometric properties as a measurement of the fear of childbirth in pregnant women.

Psychometric properties of the Center for Epidemiologic Studies Depression Scale (CES-D) in French clinical and nonclinical adults.

BACKGROUND: Previous research on the Center for Epidemiologic Studies Depression Scale (CES-D) has five main limitations. First, no study provided evidence of the factorial equivalence of this instrument across samples of depressive and community participants. Second, only one study included systematic tests of measurement invariance based on confirmatory factor analyses (CFA), and this study did not consider the higher-order factor structure of depression, although it is the CES-D global scale score that is most often used in the context of epidemiological studies. Third, few studies investigated the screening properties of the CES-D in non-English-language samples and their results were inconsistent. Fourth, although the French version of the CES-D has been used in several previous studies, it has never been systematically validated among community and/or depressed adults. Finally, very few studies have taken into account the ordered-categorical nature of the CES-D answer scale. The purpose of the study reported herein was therefore to examine the construct validity (i.e., factorial, reliability, measurement invariance, latent mean invariance, convergence, and screening properties) of the CES-D in a French sample of depressed patients and community adults. METHODS: A total sample of 469 participants, comprising 163 clinically depressed patients and 306 community adults, was involved in this study. The factorial validity, and the measurement and latent mean invariance of the CES-D across gender and clinical status, were verified through CFAs based on ordered-categorical items. Correlation and receiver operator characteristic curves were also used to test the convergent validity and screening properties of the CES-D. RESULTS: The present results: (i) provided support for the factor validity and reliability of a second-order measurement model of depression based on responses to the CES-D items; (ii) revealed the full measurement invariance of the first- and second-order measurement models across gender; (iii) showed the partial strict measurement invariance (four uniquenesses had to be freely estimated, but the factor variance-covariance matrix also proved fully invariant) of the first-order factor model and the complete measurement invariance of the second-order model across patients and community adults; (iv) revealed a lack of latent mean invariance across gender and across clinical and community subsamples (with women and patients reporting higher scores on all subscales and on the full scale); (v) confirmed the convergent validity of the CES-D with measures of depression, self-esteem, anxiety, and hopelessness; and (vi) demonstrated the efficacy of the screening properties of this instrument among clinical and nonclinical adults. CONCLUSION: This instrument may be useful for assessing depressive symptoms or for the screening of depressive disorders in the context of epidemiological studies targeting French patients and community men and women with a background similar to those from the present study.

[The VQ11, a short health-related quality of life questionnaire for routine practice in COPD patients]. / Le VQ11, un questionnaire de qualité de vie spécifique à la BPCO utilisable en clinique.

OBJECTIVE: The management of COPD aims to improve integrated indices such as health-related quality of life (HRQoL). Experts recommend repeated and methodical assessment of HRQoL, particularly by the use of questionnaires. Though these tools give pertinent information for groups of patients, they have limitations in describing the progress in one patient or indicating the prognosis. The purpose of this study is to validate a brief, self-administered HRQoL questionnaire, designed for the individual follow-up of COPD patients over a period of 3-6 months. METHOD: Following an initial validation of the contents and a review of the literature, 166 COPD patients completed an experimental version of a questionnaire including 24 items, three theoretical components (functional, psychological and relational) and 11 sub-dimensions. RESULTS: Confirmative factor analyses show a hierarchical model in respect of the current criteria (chi(2)=62.042; dl=41; ratio chi(2)/ddl=1.51; p<0.02; CFI=0.955; TLI=0.939; RMSEA=0.056; SRMR=0.054) composed of 11 items (one by a theoretical sub-dimension) distributed in three components (functional=3; psychological=4; relational=4). CONCLUSION: The questionnaire obtained, named VQ11, possesses an internal validation which satisfies international psychometric standards. It remains necessary to demonstrate whether the questionnaire satisfies the criteria of external validation and that it reveals thresholds of clinical change.
