Prevalence and trends in the childhood dual burden of malnutrition in low- and middle-income countries, 1990–2012

OBJECTIVE To describe trends in country- and individual-level dual burden of malnutrition in children <5 years, and age-stratified (<2 years, ≥2 years) country-level trends, in thirty-six low- and middle-income countries (LMIC). DESIGN Using repeated cross-sectional nationally representative data, we calculated the prevalence of malnutrition (stunting, wasting, overweight) at each survey wave, annualized rates of prevalence change for each country over time, and trends before and after 2000, for all children <5 years and separately for those </≥2 years. We examined country- (ratio of stunting to overweight) and individual-level (coexistence of stunting and overweight) dual burden in children <5 years. SETTING Demographic and Health Surveys from thirty-six LMIC between 1990 and 2012. SUBJECTS Children <5 years. RESULTS Overall malnutrition prevalence decreased in children <5 years, driven by stunting decreases. Stunting rates decreased in 78 % of countries, wasting rates decreased in 58 % of countries and overweight rates increased in 36 % of countries. Rates of change differed for children </≥2 years, with children <2 years experiencing decreases in stunting in fewer countries yet increases in overweight in more countries. Countries with nearly equal prevalences of stunting and overweight in children <5 years increased from 2000 to the final year. Within a country, 0·3-10·9 % of children <5 years were stunted and overweight, and 0·6-37·8 % of stunted children <5 years were overweight. CONCLUSIONS The dual burden exists in children <5 years on both country and individual levels, indicating a shift is needed in policies and programmes to address both sides of malnutrition. Children <2 years should be identified as a high-risk demographic.

School nurses’ perceptions and experiences with an interprofessional concussion management team in the secondary school setting

ABSTRACT Following a concussion, both cognitive and physical rest are imperative aspects of injury management. The inclusion of academic adjustments and the formation of an interprofessional concussion management team (ICMT) provide a mechanism to manage academic issues following a concussion. As one of the sole healthcare providers presents during school hours, the school nurse may offer unique insight regarding the infrastructure of an ICMT in the secondary school setting. The purpose of this study was to explore school nurses’ perceptions of and experiences with an ICMT for adolescents following a concussion in the secondary school setting. The consensual qualitative research approach was used to guide this study. Semi-structured individual telephone interviews were conducted with 15 school nurses employed in the secondary school setting across the United States. During data analysis, themes and categories were established based on a consensus process by the research team. Study findings indicated that school nurses identified several stakeholders regarding the concussion management team that are essential to include in the concussion management process. In addition to the school nurse, participants perceived an ICMT should include a physician, athletic trainer, school counsellor, teachers, and other stakeholders such as the patient and their parents. Additionally, participants discussed their perceptions of their own role as a member of an ICMT in the secondary school setting. The inclusion of an ICMT to aid the recovery following a concussion is vital to ensure proper care for the adolescent patient. Furthermore, the school nurse and athletic trainer must effectively collaborate, when possible, to ensure that concussed adolescents are allowed sufficient cognitive rest via the incorporation of academic adjustments during the recovery process.

Parents’ and Child’s Concussion History as Predictors of Parental Attitudes and Knowledge of Concussion Recognition and Response:

Background: Parents’ knowledge of and attitudes toward concussions are often vital factors that affect care for injured adolescent athletes. It is important to understand the role that parents’ personal experiences with concussions play with regard to current concussion knowledge and attitudes so that clinicians may tailor their educational approaches. Purpose/Hypothesis: The purpose of this study was to determine an association between parents’ personal experiences and their child’s experiences with concussions as well as parental concussion knowledge and attitudes. We hypothesized that parents who have personally experienced symptoms or have a child who has experienced symptoms would have better knowledge and more favorable attitudes toward concussions. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Parents of youth sport athletes (N = 234 [82 male, 144 female, 8 unreported]; mean age, 44.0 ± 6.3 years) completed a prevalidated survey for concussion knowledge (maximum score possible, 29) and attitudes (maximum score possible, 49). Higher scores indicated better knowledge and more favorable attitudes toward concussive injuries. Parents reported the frequency of concussion diagnoses and/or experiences of concussion-related symptoms and whether their child had suffered a diagnosed concussion or experienced concussion symptoms (yes/no). Spearman rank correlation and multivariable regression were used to examine the association between experience of symptom clusters (self or child) and concussion knowledge and attitudes. Results: Knowledge was moderate (mean, 23.3 ± 2.5 of 29), while attitudes prioritized disclosure (mean, 46.3 ± 3.7 of 49). Parents’ experience of the sleep-arousal symptom cluster was positively associated with concussion attitudes (r = 0.22, P = .002; β = –3.301, P = .011). Parents with children who experienced sleep-arousal and vestibular-somatic symptom clusters were weakly associated with parental concussion knowledge (sleep-arousal: r = 0.15, P = .041; vestibular-somatic: r = 0.17, P = .020; β = 0.540, P = .012). Conclusion: Our findings suggest that parents’ personal experiences with concussion-related symptoms have little effect on parental knowledge and attitudes as a whole. However, clinicians should consider particular symptom clusters that may provide insight into targets for future concussion education. According to these findings, parents of youth sport participants would benefit from increased concussion education focusing on the types of symptoms as well as the consequences of suffering a concussion.

The Current State of Sports Concussion

Concussion is a complex injury that requires a multimodal assessment to identify and manage the resulting dysfunction. To appropriately manage concussion, clinicians must be aware of the accompanying pathophysiology and dysfunction that occurs following the injury. The current best practice model of care includes symptom, motor, and neurocognitive assessment and management. Furthermore, clinicians should be aware that lifetime accumulation of head impacts may also play a role in neurologic presentation and response to concussion. This article reviews recent evidence concerning terminology, pathophysiology, epidemiology, and best practices in concussion management and potential long-term and cumulative implications of concussion.

Consumption of key food groups during the postpartum period in low-income, non-Hispanic black mothers

The postpartum period can impact diet quality and subsequently place women at greater risk for overweight or obesity. This study examined consumption of key food groups during the first 2 years postpartum among low income, non-Hispanic black, first-time mothers. Data were from the Infant Care, Feeding and Risk of Obesity Study, a cohort of 217 mother-infant dyads, followed from 3 to 18 months postpartum, collected from 2003 to 2007. At each study visit (3, 6, 9, 12, and 18 months) 24-h dietary recalls were collected. Consumption levels were compared to those recommended from the 2010 Dietary Guidelines for Americans (DGAs) for each of the following food groups: fruits, vegetables, grains, whole grains, protein foods and dairy, as well as an estimated upper limit for sugar-sweetened beverage (SSB) consumption. At each time point, mothers met recommended intake levels for grains and protein foods only. In random-intercept logistic regression models, no demographic or household characteristics were associated with a likelihood of consuming recommended levels for any of the food groups according to the DGAs. Given the low intake of fruits, vegetables, whole grains and lean protein foods and high intake of SSBs and refined grains, interventions targeting womens diet during the postpartum period are warranted.

School Nurses’ Perceived Challenges With Concussion Management Procedures in the Secondary School Setting

School nurses have an integral role in managing student health concerns throughout the school day, yet little is known about their specific role in concussion management. Therefore, the purpose of this study was to explore the challenges encountered by school nurses regarding concussion management in the secondary school setting. Twenty-two school nurses employed in the secondary school setting were interviewed via phone. We analyzed the data via the consensual qualitative research paradigm. Overall, we found school nurses face consistent challenges with their role on the concussion management team, specifically related to education of school personnel, parents, and community health-care providers. Challenging topics included the inconsistency of community health-care provider recommendations and others’ perceptions of school nurses’ preparation and training to be important members of the concussion management team. Efforts to increase concussion education and improve communication across all stakeholders of the concussion management team should be implemented.

The Effect of Body Checking Policy Changes on Concussion Incidence in Canadian Male Youth Ice Hockey Players: A Critically Appraised Topic

Clinical Scenario: Current studies have identified body checking as the most common cause of sports-related concussion in ice hockey across all divisions and levels. As a result, many hockey organizations, particularly in youth sports, have implemented rules making body checking to the head, face, and/or neck illegal. Such a rule, in Canada, makes age 13 the first age in which individuals can engage in body checking. Despite these changes, effectiveness of their implementation on the incidence of concussion in Canadian male youth ice hockey players remains unclear. Clinical Question: What is the effect of body checking policy changes on concussion incidence in male youth ice hockey players? Summary of Key Findings: Of the 3 included studies, 2 studies reported a decrease in the incidence of concussion once a body checking policy change was implemented. The third study showed an increase; however, it is important to note that this may be due, in part, to increased awareness leading to better reporting of injuries. Clinical Bottom Line: Current evidence supports a relationship between body checking policy implementation and decreased concussion incidence; however, more research is needed to understand the long-term implications of policy change and the effects in other leagues. In addition, further data are needed to differentiate between increased concussion incidence resulting from concussion education efforts that may improve disclosure and increased concussion incidence as a direct result of policy changes. Strength of Recommendation: Grade B evidence exists that policy changes regarding body checking decrease concussion incidence in male youth ice hockey players.

The Effect of Concussive Injury on Individual Game Performance in Professional Collision Sport Athletes

Clinical Scenario: Collision sports are often at higher risk of concussion due to the physical nature and style of play. Typically, initial clinical recovery occurs within 7 to 10 days; however, even this time frame may result in significant time lost from play. Little has been done in previous research to analyze how individual game performance may be affected upon return to play postconcussion. Focused Clinical Question: Upon return-to-play clearance, how does sport-related concussion affect game performance of professional athletes in collision sports? Summary of Key Findings: All 3 studies included found no significant change in individual performance of professional collision-sport athletes upon returning to play from concussive injury. One of the studies indicated that there was no difference in performance for NFL athletes who did not miss a single game (returned within 7 d) and those who missed at least 1 game. One study indicated that although there was no change in performance of NFL players upon returning to play from sustained concussion, there was a decline in performance in the 2 weeks before the diagnosed injury and appearing on the injury report. The final study indicated that there was no difference in performance or style of play of NHL athletes who missed time due to concussive injury when compared with athletes who missed games for a noninjury factor. Clinical Bottom Line: There was no change in performance upon return from concussive injury suggesting that players appear to be acutely recovered from the respective concussion before returning to play. This suggests that current policies and management properly evaluate and treat concussed athletes of these professional sports. Strength of Recommendation: Grade C evidence exists that there is no change in individual game performance in professional collision-sport athletes before and after suffering a concussion.

Epidemiology of Injuries Requiring Emergency Transport Among Collegiate and High School Student-Athletes

CONTEXT: Data regarding the epidemiology of emergency-transport incidents (ETIs) of patients with sport-related injuries are lacking. Understanding the use of emergency services by athletic trainers can help improve emergency preparedness and prehospital care for injured student-athletes. OBJECTIVE: To determine the frequencies and types of ETIs resulting from athletic participation. DESIGN: Descriptive epidemiology study. SETTING: Participating colleges and high schools during 2009-2010 to 2014-2015 and 2011-2012 to 2013-2014, respectively. PATIENTS OR OTHER PARTICIPANTS:  Student-athletes in 23 high school and 25 intercollegiate sports. MAIN OUTCOME MEASURE(S):  Data on injuries requiring emergency transport were collected by each teams athletic trainer via their respective online injury-tracking software. Athletic trainers also collected data on athlete-exposures (AEs). Emergency-transport incident frequencies and injury rates per 10 000 AEs with 95% confidence intervals (CIs) were reported. For each ETI, the sport, body part, injury mechanism, and final diagnosis were recorded. RESULTS: A total of 339 and 146 ETIs were reported in collegiate and high school players, respectively. Collegiate womens ice hockey had the highest ETI rate (1.28/10 000 AEs; 95% CI = 0.71, 1.86). In high school, football had the highest rate at 0.80 per 10 000 AEs (95% CI = 0.64, 0.97). Athletes with head or face injuries required the most transports in college (n = 71, 20.9%) and high school (n = 33, 22.6%) across all sports. Strains (n = 50, 14.7%) and fractures (n = 35, 24.0%) were the leading diagnoses for patients undergoing transport in college and high school, respectively. CONCLUSIONS: Athletic trainers should maintain a high level of emergency preparedness when working with sports that have high rates and numbers of ETIs. Athletes with injuries to the head/face required the most frequent transport across competition levels. Athletic trainers should have the appropriate equipment and protocols in place to handle these patients. Future researchers should examine the differences between field and hospital diagnoses to help improve prehospital care and decrease the likelihood of unnecessary emergency transports.

Mixed Methods Designs for Sports Medicine Research

Mixed methods research is a relatively new approach in the field of sports medicine, where the benefits of qualitative and quantitative research are combined while offsetting the others flaws. Despite its known and successful use in other populations, it has been used minimally in sports medicine, including studies of the clinician perspective, concussion, and patient outcomes. Therefore, there is a need for this approach to be applied in other topic areas not easily addressed by one type of research approach in isolation, such as the retirement from sport, effects of and return from injury, and catastrophic injury.
