Whether the research design answer the research question
In Ash et al (2017), the researchers were aiming at profiling the current family-based childhood obesity prevention as an intervention through the employment of the systematic review and the quantitative content evaluation techniques to help in the identification of the present gaps in the awareness. The method employed by the authors was a wide-ranging search approach using the databases PubMed, PsycINFO, and CINAHL. This was done to guide on the identification of the eligible interventions that can help in the prevention of childhood obesity accompanied with lively family component that was developed between 2008 and 2015. The search results reveal that the existence in the few numbers of interventions that target the diverse population and the obesity risk habits beyond the diet and the physical exercises inhibiting the process of developing a all-inclusive, custom-made intervention (Ash et al., 2017).
Li et al. (2017) performed the systematic review and meta-analysis using prospective cohort research article for the estimation of the relationship existing between sleep duration and obesity during childhood. Through the employment of the study method, the researchers managed to respond to the research question i.e., the short sleep duration leads to the increase in the exposure to childhood obesity (Li et al., 2017).
Aftosmes-Tobio et al (2016) aimed at describing how the media use and media-associated parenting approaches and the expertise are operationalized in the research work for the purposes of determine if the research studies calculated the ecological aspects such as persons, families, or the societal-level aspects are directly linked to the media parenting practices. The researchers utilized standardized. The multi-stage process to identify as well as the screened article was concerned about the parenting and childhood obesity. The outcome of the study is revealing that exhaustive measurements of the media use that is reflecting on the present trends in the technology and the diverse contexts of use are required to help in understanding media use as well as the parent regulation process in preventing child exposure to media (Aftosmes-Tobio et al., 2016).
Whether the study sample participants were representatives
In Ash et al (2017), a total of 84 samples from the underserved population and non-traditional families and as well as the racial or ethnic composition were used. Even though this is a smaller sample, it gives a clear picture of the role played by family-based childhood obesity prevention interventions (Ash et al., 2017).
The researchers in Li et al. (2017) used a total of 12 studies which represented a population of 15. This sample population is less based on the number of study articles used for the review. Therefore, the study outcome cannot be used for the generalization of what is happening to children in terms of sleep duration on obesity and BMI (Li et al., 2017).
In Aftosmes-Tobio et al (2016), a sample 103 studies were used by the researchers. The articles used are adequate to give the required information concerning media parenting within the childhood obesity study context (Aftosmes-Tobio et al., 2016).
Comparing and contrasting the limitation
The limitation showed by the researcher in Ash et al (2017) is that the focus was on the articles that were published over relatively narrow time-period. The researchers also failed to evaluate the effectiveness or the quality of the intervention thus limiting the potential of the review. The outcome of the study can be influenced by the number as well as the choice of the databases searched thus subjecting it to the publication bias (Ash et al., 2017).
The limitations presented by Li et al. (2017) is that even though a comprehensive literature search was done, there was bias in the publication that was discovered through the use of Begg’s test which was re-evaluated RR through the use of the trim and fill technique. Many cohort used were from the United States and Europe thus failure of the research outcomes to represent the Asian and the African individuals. The researchers failed to consider the impacts of sleep quality and patterns on the weight gain of a child (Li et al., 2017).
In Aftosmes-Tobio et al (2016), the limitation pointed out by the researcher is that there was a restriction of the review to English-language and non-intervention studies and this might have caused the limitation of the final sample of studies available for evaluation. The researchers failed to assess the risk of the bias across studies or the strength of the evidence for study outcomes because they were not important to the research (Aftosmes-Tobio, et al., 2016).
Whether this quantitative research study would be considered as a support to the selected problem
The key themes identified by the researchers included intervention characteristics, article characteristics, and the sample characteristics. The rise in childhood obesity is a burden to the nation. Therefore, efforts are being made to have an effective intervention. The researchers showed the need of having intervention effort, especially in the low- and middle-income nations. Ash et al (2017) study is therefore revealing the importance of family-based childhood obesity intervention that can be used to tackle the issue of obesity among children (Ash et al., 2017).
In Li et al. (2017), the authors used a few samples. Nevertheless, the outcome reveals an important aspect concerning the importance of sleep duration on the reduction of obesity which is an important issue of discussion. This intervention can therefore be used to address the problem of obesity among children (Li et al., 2017).
In Aftosmes-Tobio et al (2016), the parenting practices as a measure is concerned with the larger rule of specific towards restricting the screen time. Even though 60 percent of the studies measured at least a single ecological factor, child particular and community-level were hardly measured. The research work is important in addressing the problem since it shows the importance of media use and the parenting regulation on the exposure of a child to obesity (Aftosmes-Tobio et al., 2016).
