Measurement of external food cue responsiveness in preschool-age children: Preliminary evidence for the use of the external food cue responsiveness scale.

ABSTRACT: BACKGROUND:Conditioned eating in response to external food cues may contribute to obesity risk in young children. OBJECTIVES:To develop a brief, parent-reported scale to measure external food cue responsiveness for preschool-age children. METHODS:Focus groups with parents of preschool-age children were conducted to create an initial pool of items reflecting children's behavioral responses to external food cues. Items were included in a nationally-distributed online survey of parents of preschool-age children (n?=?456). Factor analysis was used to reduce the initial item pool, the scale's psychometric properties were assessed, and scores were correlated with reported snacking behaviors. RESULTS:Nine items met inclusion criteria in the final scale, which had high internal consistency (alpha?=?0.86). Final scores were the mean across the nine items. External food cue responsiveness was greater among children with, versus without, usual TV advertisement exposure. Furthermore, greater external food cue responsiveness mediated the relationship between children's usual TV advertisement exposure and snacking during TV viewing. Findings remained statistically significant when adjusted for food responsiveness as measured with the Child Eating Behavior Questionnaire. CONCLUSIONS:Findings provide preliminary evidence that external food cue responsiveness is measurable by parental report in preschool-age children.

Project description:BackgroundThere are many causes of visual impairment, and even blindness, which are treatable or at least preventable. Two such conditions are strabismus (crossed-eye, squint) and refractive error (visual image not focused on the most sensitive part of the retina). If these are not detected and corrected at an early age, they can lead to an irreversible impairment known as amblyopia (lazy eye). Pediatric vision screening and subsequent treatment for amblyopia and amblyogenic risk factors are thus key to preventing vision loss. Furthermore, vision screening can detect moderate to high hyperopia, which has been found to be associated with poor school readiness. Evidence-based recommendations call for screening children at 3-5 years of age; they are old enough to cooperate, but still within the window of effective intervention. However, these recommendations have yet to be universally implemented as the standard of care.MethodsThis paper integrates a review of the literature and the international experience of preschool vision screening with the findings from a preliminary feasibility study of expanded screening in Israel to formulate a discussion of the current health policy challenge in Israel and the options for addressing it. The advantages and disadvantages of various venues for vision screening are discussed.FindingsScreening by optometrists in Mother and Child Health Centers, as implemented in a recent pilot project in the Jerusalem District, would allow the most comprehensive testing. Photo-screening in preschools would reach the most children, but at the cost of missing hyperopia (farsightedness). Either approach would probably constitute improvements over the current situation. The relative strengths of the two approaches depends in part on the ability to purchase automatic screening equipment (and the efficacy of that equipment) vs. the ongoing cost of paying trained personnel.ConclusionsFurther research should be conducted in Israel to determine the prevalence of refractive errors, so that best practices can be established for Israel's population and social needs. In the interim, the Ministry of Health should promptly implement the inclusion of preschool visions screening for children in the approved "basket of services" covered by the National Health Insurance Laws, using photo-screening, including collection of the clinical data.

Project description:We previously have shown that cue-induced alcohol craving and propensity for higher drinking are modulated by allelic differences in SLC6A4 associated with serotonin transporter (5-HTT) expression level alterations. In an independent study, we characterized another polymorphism, SNP rs1042173, in 3'-untranslated region (3'-UTR) of the same gene, which also altered 5-HTT expression levels; the T allele of rs1042173 was associated with lower mRNA and protein levels. In subsequent analyses, the TT genotype was found to be associated with higher drinking intensity in alcohol-dependent (AD) individuals of Caucasian descent. Building upon these findings, we hypothesized that the low-expressing TT genotype associated with intense drinking would predict higher craving for alcohol in AD individuals. In this pilot study, we sought to test our hypothesis by examining 34 Hispanic AD volunteers (mean age, 34.8 years) for rs1042173 genotype-based [i.e., TT versus TG/GG (Gx)] differences in subjective response to alcohol. We employed a human laboratory paradigm and analyzed the data using a linear mixed-effects model (SAS® PROC MIXED) to assess treatment, cue procedures, and genotype main effects as well as the two-way interaction effects between them. On subjective "urge to drink" and "crave for a drink," we found a significant main effect of the cue experiment (p ≤ 0.01) and an interaction effect between genotype and cue effects (p < 0.05). TT genotype was associated with higher urge to drink (p = 0.002) and crave for a drink (p = 0.005) when exposed to alcohol cue. Our results not only support the hypothesis that rs1042173 is a genetic marker for cue-induced alcohol craving among AD males but also are suggestive of a neurobiological mechanism associated with the rs1042173-TT genotype that triggers a disproportionate craving in response to alcohol consumption, which in turn may lead to more intense drinking. Future studies with larger sample sizes are needed to characterize the interactive effects of the serotonin transporter-linked polymorphic region (5'-HTTLPR)-L-allele reported in our previous study and of the rs1042173-TT genotype on cue-induced alcohol craving.
