Comparison of ten policy options to equitably reduce children's exposure to unhealthy food marketing.

OBJECTIVE: Reducing children's exposure to unhealthy food marketing is crucial to combat childhood obesity. We aimed to estimate the reduction of children's exposure to food marketing under different policy scenarios and assess exposure differences by socio-economic status. DESIGN: Data on children's exposure to unhealthy food marketing were compiled from a previous cross-sectional study in which children (n 168) wore wearable cameras and Global Positioning System (GPS) units for 4 consecutive days. For each exposure, we identified the setting, the marketing medium and food/beverage product category. We analysed the percentage reduction in food marketing exposure for ten policy scenarios and by socio-economic deprivation: (1) no product packaging, (2) no merchandise marketing, (3) no sugary drink marketing, (4) no confectionary marketing in schools, (5) no sugary drink marketing in schools, (6) no marketing in public spaces, (7) no marketing within 400 m of schools, (8) no marketing within 400 m of recreation venues, (9) no marketing within 400 m of bus stops and (10) no marketing within 400 m of major roads. SETTING: Wellington region of New Zealand. PARTICIPANTS: 168 children aged 11-14 years. RESULTS: Exposure to food marketing varied by setting, marketing medium and product category. Among the ten policy scenarios, the largest reductions were for plain packaging (60·3 %), no sugary drink marketing (28·8 %) and no marketing in public spaces (22·2 %). There were no differences by socio-economic deprivation. CONCLUSIONS: The results suggest that plain packaging would result in the greatest decrease in children's exposure to food marketing. However, given that children are regularly exposed to unhealthy food marketing in multiple settings through a range of marketing mediums, comprehensive bans are needed to protect children's health.

Where do the children play? An objective analysis of children's use of green space.

Green space is important for health, yet, objective research on children's use of green space is sparse. This study aimed to objectively assess children's use of green space in both public and private settings during their summer leisure time, using wearable cameras. Images from cameras worn by 74 children were analysed for green space use over 4 days. Children spent an average of ∼1/10 h of leisure time in green space in the summer months, were physically active 68%, and with others 85%, of the time. Green spaces are important places for children's health because they are places they frequent and places where they are physically active and socialize. Wearable cameras provide an effective method for objective assessment of green space use.

Space-time analysis of unhealthy food advertising: New Zealand children's exposure and health policy options.

Reducing children's exposure to unhealthy food advertising is an accepted strategy to end childhood obesity. This study aimed to (i) measure children's space-time exposures to unhealthy food advertising in public outdoor spaces, using GPS and wearable cameras; and (ii) test effectiveness of banning options. We compiled data (collected July 2014-June 2015) on 138 12-year-old children in Wellington, New Zealand, using wearable cameras and GPS devices worn over 4 days. In 2017-18, we linked 59 150 images taken in public outdoor spaces to GPS data. Of these, 1631 contained unhealthy food advertising exposures, defined as ≥50% of an advertisement observed in each image. We examined spatial patterns using kernel density mapping and graphed space-time trends. We interpolated a kriged exposure rate across Wellington to estimate exposure reductions for potential bans. Children were exposed to 7.4 (95% CI 7.0-7.8) unhealthy food advertisements/hour spent in outdoor public spaces. Exposures occurred in shopping centres, residential areas and sports facilities, commonly involving fast food, sugary drinks and ice cream. Peak exposure times were weekend afternoons/evenings and weekdays before/after school. In Wellington, we estimated that banning such advertising within 400 m of playgrounds would yield a 33% reduction in exposure, followed by in residential areas (27%), within 400 m of schools (25%), and 50% for a ban combining all above. This work documents the extent of children's exposure to unhealthy food advertising and the potential impact of bans. Given the ubiquity of advertising in public spaces, this New Zealand research offers innovative methods and findings likely relevant in other jurisdictions.

Children's healthy and unhealthy beverage availability, purchase and consumption: A wearable camera study.

Children's sugar-sweetened beverages (SSBs) consumption presents significant risks for obesity, type 2 diabetes and dental health. But there is a lack of objective data on beverages in children's overall environments. This study aimed to determine the nature and extent of children's beverage availability, purchase and consumption, throughout their day, using wearable cameras for data collection. Data were sourced from 'Kids'Cam NZ', a study in which randomly-selected New Zealand children (n = 168; 11-14y, mean 12.6y) wore cameras for four days (Thursday-Sunday), automatically taking a photo every 7s. Using content analysis, Thursday and Saturday images (n = 700,201) were systematically analysed. On average, 18.9 (95% CI 16.8, 21.4) drinks/day were available to the children (n = 158), of which 7.5 (95% CI 5.8, 9.7; 39.7%) were non-core drinks, including 6.4 (95% CI 5.0, 8.3; 33.9%) SSBs. At school and home, core drinks (water and unflavoured milk) were the most available. In all other locations in which children spent time (e.g., recreation venues and food retail outlets) non-core drinks dominated, at rates 1.5-5 times that of core drinks availability. Almost all drinks (n = 17; 10.8%) the children purchased were non-core. On average, children (n = 111; 70.3%) consumed a drink 2.6 (95% CI 2.1, 3.1) times/day, including one (95% CI 0.7, 1.3) SSB. At school and home core drinks predominated. SSBs were available to most children in all locations in which they spent time, and dominated their drinks purchases and consumption. SSBs appear to be a typical feature of children's everyday environments, almost certainly making it difficult for children's beverage intakes to align with guidelines. The findings support calls for governments to urgently enact the SSB-related actions in the WHO Commission's Ending Childhood Obesity implementation plan and, in turn, improve child health.

Studying third-parties and environments: New Zealand sun-safety research.

Wearable cameras have been used to study health behaviours, but their utility in assessing third-party behaviours and the built environment is uncertain. This paper reports on the feasibility of using wearable cameras for this purpose in a study of sun-protective behaviours and shade availability during school lunch-breaks. The Kids'Cam study provided 168 children (aged 11-13 years), recruited from 16 randomly selected schools in the Wellington region of New Zealand, with wearable cameras. The devices automatically captured images every 7 s from the child's perspective. Images captured during school lunch-breaks by a random sample of 15 children who took part during terms 4 and 1 (October 2014-April 2015) were selected and assessed for usability. The feasibility of studying third-party sun-protective behaviours and school shade availability was assessed for a subset of 320 images. Of the 3492 eligible lunch-break images, 96.4% were useable; the remainders were excluded due to obstruction, blurriness or unsuitable camera position. Overall, 1278 children and 108 shade structures were observed in the sample images. The use of shade, hats, sleeves, collars and sunglasses could be determined for 97.0%, 77.2%, 74.4%, 47.6% and 54.9% of children, respectively. All shade structures could be classified according to type, and canopy composition could be assessed for 95.4% of structures. Wearable cameras are a feasible tool for assessing sun-safety, particularly shade availability, hat wearing and shade use. This methodology could be used to objectively study other third-party health-related behaviours, and other features of the built environment.

Are children smoke-free at home? Using wearable cameras to study children's exposure to smoking and smoking paraphernalia in private spaces.

BACKGROUND: There is limited evidence available on the nature of children's exposure to smoking and smoking paraphernalia in private spaces (homes and cars). We aimed to evaluate the extent and nature of children's exposure to smoking in these settings using image data captured by wearable cameras. METHODS: One-hundred and sixty-eight children wore wearable cameras for 4 days that automatically took pictures every 7 s. Images captured in private spaces (n = 140,818) by children living in households with a smoker (n = 34) were screened for instances of smoking and smoking paraphernalia. RESULTS: A total of 37 incidents of smoking-four indoor, 21 outdoor, and two in-vehicles-and 62 incidents of smoking paraphernalia were observed. Most smoking incidents in homes (21 of 33) took place outdoors. CONCLUSIONS: The findings support health promotion efforts to make smokers more aware that smoking paraphernalia may normalize smoking for children. The methodology (wearable cameras) appears to have high utility for studying health behaviours in private spaces.

Quantifying the Nature and Extent of Children's Real-time Exposure to Alcohol Marketing in Their Everyday Lives Using Wearable Cameras: Children's Exposure via a Range of Media in a Range of Key Places.

AIMS: Children's exposure to alcohol marketing is typically measured using self-report data, television viewing data or street marketing audits, which are subject to bias and often do not provide quantifiable measures of daily exposure. This article describes an innovative methodology to capture the world in which children live using wearable cameras. SHORT SUMMARY: Children wearing wearable cameras were exposed 4.5 times per day to alcohol marketing in multiple places and via a range of marketing media. The results reinforce calls for legislative restrictions and a global response to alcohol marketing in order to protect children and reduce alcohol-related harm. METHODS: Children aged 11-13 years (n = 167) wore cameras that automatically captured images approximately every 7 s for a 4-day period between June 2014 and July 2015. Content analysis of images (n = 700,000) was manually undertaken to assess children's exposure to alcohol marketing. RESULTS: On average, children were exposed to alcohol marketing 4.5 (95% CI: 3.3, 6.0) times per day, excluding within off-licence retailers, on screens and product packaging. Children were exposed at home (47%), on-licence alcohol retailers (19%), off-licence shop fronts (16%) and sporting venues (12%), and via sports sponsorship (31%) and shop front signage (31%) and merchandise (25%). The highest exposure rates were found among Maori (5.4 times higher than New Zealand European) and Pacific (3.0 times higher than New Zealand European), and boys (2.0 times higher than girls). CONCLUSIONS: These findings highlight the urgent need to implement strict legislative restrictions on all forms of alcohol marketing to fulfil the World Health Organization Global Alcohol Strategy.

[Alcohol's impact on children and families. A population survey]. / Daño a niños y sus familias por el consumo de alcohol: resultados de una encuesta poblacional.

INTRODUCTION: Alcohol is widely used among young families, and leisure time is frequently family time. Heavy alcohol consumption can adversely affect children. The objective of this work is to measure the harm to others in Chile. SUBJECTS AND METHOD: This descriptive and probabilistic study forms part of a collaborative research funded by Thai Health and WHO. The survey was adapted by co-researchers and applied to a nationally representative sample of 1500 Chileans over 18years of age. RESULTS: A total of 408 respondents (27.2%) lived with children at home. Of this total, 10.5% felt that the use of alcohol by any member of the family had adversely affected a child. The most common adverse effects were verbal violence (29.7%), domestic violence (23.1%), unsupervised homes (18.7%), lack of money to provide basic needs of the child (14.3%), and physical violence (7.7%). Furthermore, in 6.6% of the cases child or family services agencies became involved. In almost half of the cases (46.3%), the drinker was the father, mother or step-parents. This was followed by other relatives (24.4%) and brothers (4.9%), or guardian of the child (2.4%). CONCLUSION: These data support the clinical observation that alcohol is common in Chilean homes. Its consumption not only damages the physical and mental health of the drinker but also those around him. Verbal violence and witnessing serious physical violence are frequent issues, as well as economic problems that end up with the inability to provide the child with its basic needs.

Capturing exposures: using automated cameras to document environmental determinants of obesity.

Children's exposure to food marketing across multiple everyday settings, a key environmental influence on health, has not yet been objectively documented. Wearable automated cameras (ACs) may have the potential to provide an objective account of this exposure. The purpose of this study is to assess the feasibility of using ACs to document children's exposure to food marketing in multiple settings. A convenience sample of six participants (aged 12) wore a SenseCam device for two full days. Following which, participants attended a focus group to ascertain their experiences of using the device. The collected data were analysed to determine participants' daily and setting specific exposure to 'healthy' and 'unhealthy' food marketing (in minutes). The focus group transcript was analysed using thematic analysis to identify the common themes. Participants collected usable data that could be analysed to determine participant's daily exposure (in minutes) to 'unhealthy' food marketing across a number of everyday settings. Results from the focus group discussion indicated that participants were comfortable wearing the device, after an initial adjustment period. ACs may be an effective tool for documenting children's exposure to food marketing in multiple settings. ACs provide a new method for documenting environmental determinants of obesity and likely other environmental impacts on health.

[The harm to others from drinking: A population study]. / Daño a terceros producido por el alcohol: resultados de un estudio poblacional en Chile.

BACKGROUND: Alcohol can harm both drinkers and their human environment. Most of research in Chile has focused on the drinker. This work focuses on the damage to others. Governmental expenditures due to drinking are estimated to quadruple the income earned through taxation. AIM: To report the results of a population survey conducted in Chile in 2013 to assess the harm done to others from drinking by a known or unknown drinker. MATERIAL AND METHODS: A household survey of a sample of 1500 subjects living in urban areas, predominantly over 50.000 inhabitants, was conducted by trained interviewers. RESULTS: A significant number of respondents reported that the effect of alcohol consumption by third parties was somewhat (18.7%) or very negative (14.8%). The most frequent negative effects were verbal abuse (37.4%), being bullied (17.4%), feeling fearful at home or in a private meeting (19.6%) and family problems (16.9%). CONCLUSIONS: About one third of Chileans surveyed have suffered negative effects due to alcohol consumption of a known or unknown drinker. This finding signals the need of designing public policies addressed to minimize or prevent collateral effects of drinking.

MRI of transforaminal lumbar interbody fusion: imaging appearance with and without the use of human recombinant bone morphogenetic protein-2 (rhBMP-2).

PURPOSE: To describe the vertebral endplate and intervertebral disc space MRI appearance following TLIF, with and without the use of rhBMP-2, and to determine if the appearance is concerning for discitis/osteomyelitis. MATERIALS AND METHODS: After institutional review board approval, 116 TLIF assessments performed on 75 patients with rhBMP-2 were retrospectively and independently reviewed by five radiologists and compared to 73 TLIF assessments performed on 45 patients without rhBMP-2. MRIs were evaluated for endplate signal, disc space enhancement, disc space fluid, and abnormal paraspinal soft tissue. Endplate edema-like signal was reported when T1-weighted hypointensity, T2-weighted hyperintensity, and endplate enhancement were present. Subjective concern for discitis/osteomyelitis on MRI was graded on a five-point scale. Generalized estimating equation binomial regression model analysis was performed with findings correlated with rhBMP-2 use, TLIF level, graft type, and days between TLIF and MRI. RESULTS: The rhBMP-2 group demonstrated endplate edema-like signal (OR 5.66; 95% CI [1.58, 20.24], p = 0.008) and disc space enhancement (OR 2.40; 95% CI [1.20, 4.80], p = 0.013) more often after adjusting for the TLIF level, graft type, and the number of days following TLIF. Both groups had a similar temporal distribution for endplate edema-like signal but disc space enhancement peaked earlier in the rhBMP-2 group. Disc space fluid was only present in the rhBMP-2 group. Neither group demonstrated abnormal paraspinal soft tissue and discitis/osteomyelitis was not considered likely in any patient. CONCLUSIONS: Endplate edema-like signal and disc space enhancement were significantly more frequent and disc space enhancement developed more rapidly following TLIF when rhBMP-2 was utilized. The concern for discitis/osteomyelitis was similar and minimal in both groups.

Differential disruption of blood-brain barrier in severe traumatic brain injury.

BACKGROUND: Traumatic brain injury (TBI) is a significant cause of death and disability in young adults, but not much is known about the incidence and characteristics of blood-brain barrier (BBB) dysfunction in this group. In this proof of concept study, we sought to quantify the incidence of BBB dysfunction (defined as a cerebrospinal fluid (CSF)-plasma albumin quotient of ≥0.007) and examine the relationship between plasma and CSF levels of proteins and electrolytes, in patients with severe TBI. METHODS: We recruited 30 patients, all of whom were receiving hypertonic 20 % saline infusion for intracranial hypertension and had external ventricular drains in situ. Simultaneous CSF and blood samples were obtained. Biochemical testing was performed for sodium, osmolality, potassium, glucose, albumin, immunoglobulin-G, and total protein. RESULTS: Eleven patients (37 %) showed evidence of impairment of passive BBB function, with a CSF-plasma albumin quotient of ≥0.007. There were strong positive correlations seen among CSF-plasma albumin quotient and CSF-plasma immunoglobulin-G quotient and CSF-plasma total protein quotient (r = 0.967, P < 0.001 and r = 0.995, P < 0.001, respectively). We also found a higher maximum intracranial pressure (24 vs. 21 mmHg, P = 0.029) and a trend toward increased mortality (27 vs. 11 %, P = 0.33) in patients with BBB disruption. CONCLUSIONS: In summary, passive BBB dysfunction is common in patients with severe TBI, and may have important implications for effectiveness of osmotherapy and long-term outcomes. Also, our results suggest that the CSF-plasma total protein quotient, a measurement which is readily available, can be used instead of the CSF-plasma albumin quotient for evaluating BBB dysfunction.

The distribution of harmful product marketing in public outdoor spaces and the effectiveness of marketing bans.

Children's exposure to the marketing of harmful products in public outdoor spaces may influence their consumption of those products and affect health into adulthood. This study aimed to: i) examine the spatial distribution of children's exposure to three types of marketing-related 'harms' (alcohol, unhealthy food, and gambling) in outdoor spaces in the Wellington region, New Zealand/Aotearoa; ii) compare differences in the distribution of harms by socioeconomic deprivation; and iii) estimate the effectiveness of different policies that ban such marketing. Data were from 122 children aged 11-13y who wore wearable cameras and GPS devices for four consecutive days from July 2014 to June 2015. Images were analysed to identify harmful product marketing exposures in public outdoor spaces. Eight policy scenarios were examined to identify the effectiveness of marketing bans, for all children and by socioeconomic deprivation. Children's ratio of harmful marketing was higher for children from high deprivation households and was also found to cluster, with hots spots observed around city centers. The effectiveness of marketing bans depended on the target setting and ban area, with banning 400 m around bus stops leading to the largest reduction. Effectiveness varied also by type of harm and socioeconomic deprivation. For example, banning alcohol marketing in residential areas was estimated to have a larger effect on exposure reduction for children from high deprivation households. Our findings suggest that alcohol, unhealthy food and gambling marketing often cluster outdoors and that targeted bans of such marketing would likely improve child health and, for some banning scenarios, promote equity.

Discursive and Non-discursive Symbolization during couple's Conflict.

The purpose of this article was exploring the role of discursive and non-discursive symbolization - specifically gestures - in the negotiation of differences in couples´ interactions. Five married heterosexual couples were invited to hold a conversation about an unsolved problem in their relationship. A videographic analysis was carried out to explore gestures in dialogical sequences and Microgenetic Semiotic Analysis (ASM) was conducted. The results showed that gestures complemented verbal signs as semiotic devices in the regulation of meaning construction and differences in negotiation, displaying strategies for facing and avoiding conflict, as well as resources for undergoing tension dealing with personal objectives and emotional difficulties; Its role is discussed as preparation of the verbal communicative expression, as devices for self-regulation and access to tension relief. Further, the discussion addresses their function as paths for encounter, mutuality and closeness.

Food store environment examination - FoodSee: a new method to study the food store environment using wearable cameras.

INTRODUCTION: Food environments shape food behaviours and are implicated in rising rates of obesity worldwide. Measurement of people's interactions with food stores is important to advance understanding of the associations between the food environment and in-store behaviour. This paper describes a new method, Food Store Environment Examination (FoodSee) to measure people's interaction with the food store environment in a feasibility study focused on convenience stores and children. METHODS: One hundred and sixty-eight randomly selected children (aged 11-13 years) recruited from 16 randomly selected schools in Wellington, New Zealand, used wearable cameras for 4 days that recorded images every 7 s. The study was conducted from July 2014 to June 2015. All images of convenience stores and service stations, and a sample of images from supermarkets, were evaluated to determine the feasibility of assessing food availability and marketing. The outcomes of interest assessed were: food product availability, placement, packaging, branding, price promotion, purchases and consumption. RESULTS: Thirty-seven children (22%) visited a convenience store or service station at least once during the study period. In total, there were 65 visits to 34 different stores. Seven hundred and nineteen images revealed the in-store environment. Of those, 86.1% were usable and able to be analysed for the outcomes of interest. CONCLUSIONS: The FoodSee methodology provides a promising new method to study people's interaction with the in-store food environment. The evidence generated will be valuable in understanding and improving the food store environment within which people shop, and will contribute to efforts to address obesity globally.

Prime Minister for a day: children's views on junk food marketing and what to do about it.

AIMS: This study explored children's awareness of and engagement with food marketing, and their views on action to address it. METHODS: A purposeful sample of 33 children (11-13 years) from the Wellington region of New Zealand were interviewed. RESULTS: Children were knowledgeable about food marketing, although most were not aware of the extent to which they were exposed. Children did not distinguish 'marketing to children' from other marketing. According to the children, they were frequently exposed to food marketing, and persuaded, against their better judgement, to purchase food they knew to be harmful to their health. As many children recognised the unhealthy nature of the food marketed to them, they agreed they would take action to reduce junk food marketing if they were Prime Minister for a day. Interventions included making food marketing honest, providing nutrition information, removing billboards and increasing the promotion of healthy food. CONCLUSIONS: These findings suggest children's exposure to junk food marketing may cause them physical, mental and moral harm, in direct contradiction of the New Zealand self-regulatory code for marketing. The children's views align with the World Health Assembly's recent decision to endorse initiatives to end childhood obesity, including restricting marketing of unhealthy foods.

Quantifying Children's Non-Supermarket Exposure to Alcohol Marketing via Product Packaging Using Wearable Cameras.

OBJECTIVE: The aim of this research was to quantify children's exposure to alcohol marketing via product packaging using wearable cameras, observing sociodemographic differences and contextual features of exposure. METHOD: In Wellington, New Zealand, 167 children (ages 11-13; 53% girls) wore wearable cameras for 4 consecutive days. The cameras automatically captured images approximately every 7 seconds. Image data (n = 700,000 images) were coded through content analysis to determine the extent of children's exposure to alcohol marketing via product packaging. Negative binomial regression models were used to calculate rates of exposure per day and to examine differences between groups. RESULTS: Children were exposed to alcohol marketing via product packaging 7.7 times per day, on average. Product packaging contained limited health information and lacked defining features that could provide visual cues to children to differentiate alcohol from other commodities. No statistically significant differences by sociodemographic characteristics were detected. CONCLUSIONS: Children are frequently exposed to alcohol marketing via product packaging. Such exposure normalizes alcohol in children's environments and fails to send accurate information to children about the health risks associated with alcohol consumption. Mandatory labeling on alcohol product packaging, including prominent health warnings (text, pictorial, and graphic), or plain packaging, provides governments an opportunity to substantially reduce children's overall exposure to alcohol marketing and potentially increase children's awareness of the risks associated with alcohol consumption.

In vivo expression technology (IVET) selection of genes of Rhizobium leguminosarum biovar viciae A34 expressed in the rhizosphere.

IVET was used to identify genes that are specifically expressed in the rhizosphere of the pea-nodulating bacterium Rhizobium leguminosarum A34. A library of R. leguminosarum A34 cloned in the integration vector pIE1, with inserts upstream of a promoter-less purN:gfp:gusA, was conjugated into purN host RU2249 and recombined into the genome. After removal of colonies that expressed the reporter genes of the vector under laboratory conditions, the library was inoculated into a nonsterile pea rhizosphere. The key result is that 29 rhizosphere-induced loci were identified. Sequence analysis of these clones showed that a wide variety of R. leguminosarum A34 genes are expressed specifically in the rhizosphere including those encoding proteins involved in environmental sensing, control of gene expression, metabolic reactions and membrane transport. These genes are likely to be important for survival and colonization of the pea rhizosphere.

Sun protection and shade availability in New Zealand's outdoor recreation spaces.

AIMS: We aimed to investigate sun protection behaviours and shade availability in outdoor recreation spaces using images captured by children who, in 2014/15, wore wearable cameras for four consecutive days. METHODS: The 168 participants visited 16 outdoor recreation spaces between 10am and 4pm, capturing 378 images, on average, in each setting. People observed in the images (n=2,635) were coded for age, sex, clothing worn (38 clothing types) and shade used. Mean temperature and ultraviolet index (UVI) values were linked with the time-stamped and geo-referenced images. RESULTS: The UVI in most settings was high enough to warrant sun protection, but only 4.3% of people wore sun-protective hats (broad-brim, bucket and legionnaire styles) and 10.7% used shade. Areas most popular with children, including playground equipment, beach sand and pool areas, had little or no shade available. CONCLUSIONS: Despite New Zealand having the highest incidence of melanoma skin cancer in the world, the results indicate that few New Zealanders wear hats and seek shade in outdoor recreation settings. The findings highlight the need to improve policy and environmental support for skin cancer prevention activities.

Sun Protection Among New Zealand Primary School Children.

Schools are an important setting for raising skin cancer prevention awareness and encouraging sun protection. We assessed the clothes worn and shade used by 1,278 children in eight schools in the Wellington region of New Zealand. These children were photographed for the Kids'Cam project between September 2014 and March 2015 during school lunch breaks. Children's mean clothing coverage (expressed as a percentage of body area covered) was calculated. Data on school sun-safety policies were obtained via telephone. Mean total body clothing coverage was 70.3% (95% confidence interval = 66.3%, 73.8%). Body regions with the lowest mean coverage were the head (15.4% coverage), neck (36.1% coverage), lower arms (46.1% coverage), hands (5.3% coverage), and calves (30.1% coverage). Children from schools with hats as part of the school uniform were significantly more likely to wear a hat (52.2%) than children from schools without a school hat (2.7%). Most children (78.4%) were not under the cover of shade. Our findings suggest that New Zealand children are not sufficiently protected from the sun at school. Schools should consider comprehensive approaches to improve sun protection, such as the provision of school hats, sun-protective uniforms, and the construction of effective shade.
