Abstract
Improving understanding of the intention to choose plant-based food is an important element of climate change mitigation. A cross-sectional survey of 454 North American adults was used to predict their dietary-change intentions from the theory of planned behavior (TPB) and the more-recently proposed theory of behavioral choice (TBC). The TPB accounted for 65 percent of the variance in intentions and the TBC accounted for a significantly greater (80 percent) proportion of variance. The strongest predictors of intention were the TBC's sense of obligation, attitude-values-affect (AVA), and habit, and the TBP's social norms. Five interactions also contributed in small but significant ways toward the accounting of the participants' food-choice intentions. Policy implications are discussed.

Abstract
Environmental factors such as air pollution and climate change have far-reaching implications for human health, and increasing evidence supports a link between planetary health and many common urological conditions. We summarize these links and outline the data for some dietary and lifestyle changes that have joint benefits for both urological and planetary health. PATIENT SUMMARY: Steps to reduce our impact on the environment can also reduce the risk of urological cancers (bladder, prostate, and kidney cancers), urinary tract infections, kidney stones, and erectile dysfunction, and may have a positive impact on sperm quality. Simple steps such as reducing meat and dairy consumption, increasing exercise levels (e.g. through active commuting), and supporting the preservation of greenspace can benefit both personal health and the environment.

Abstract
BACKGROUND Fiber, potassium and calcium are nutrients of public health concern and their intakes in the United States are alarmingly low. The usage of nutrition facts labels has been reported to increase the odds for dietary reference intake of fiber in some studies. The overall evidence, however, is mixed, as some studies suggested that nutrition facts panels have little to no effect on average measures of diet quality. Here, we investigated whether the usage of nutrition facts labels was associated with meeting U.S. intake recommendations for three nutrients of public health concern: fiber, potassium and calcium. METHODS We used cross-sectional multistage, stratified, clustered and probability sampling design data from the U.S. National Health and Nutrition Examination Surveys 2017-2020 cycle. The sample included 5,416 individuals aged 20 years or older, which may be extrapolated to represent 146,841,866 US Americans. Nutrient intakes were compared among individuals reading nutrition facts panels "frequently", "sometimes" or "rarely" using applied survey data analyses techniques (including multivariate logistic regression and marginsplots). RESULTS We observed substantial sociodemographic differences between the three groups. Frequent readers were significantly more likely to be female and had higher educational levels. On average, they were also significantly older as compared to rare readers. Fiber intake in g/d was highest in frequent readers (17.09) and lowest in rare readers (14.64). The proportion of participants that met dietary fiber intake recommendations was almost four times higher in the frequent readers group (12.69%) as compared to the rare readers group (3.69%). In a bivariate logistic regression model, frequent label reading significantly increased the odds for meeting the fiber recommendations in Dietary Guidelines for Americans (OR: 2.15, p < 0.001). Rarely reading labels decreased the odds (OR: 0.57, p = 0.003). These odds remained essentially unchanged after adjusting for sociodemographic covariates, diabetes status and body mass index (OR: 1.84, p = 0.004; and OR: 0.62, p = 0.022). CONCLUSIONS Nutrition facts panel reading associates with fiber intake. Our findings have potential implications for public health nutrition strategies that may center around educational work.

Abstract
Background Healthy eating habits during childhood have been identified as a foundational support for the growth, development, and intellectual well-being of schoolchildren and as a protection against diseases that affect learning and functional capacity. This study examined the eating habits of the previous day, weekly, and daily between Nigerian children in rural and urban elementary schools. Methods Data were collected between March and May 2021 with an instrument extracted from the Health and Attainment of Pupils in a Primary Education Network Survey (HAPPEN survey). Participants for the study were school children (aged 7-13 years). The multistage sampling technique was used to draw samples from the target population. Two schools were randomly selected for the study (one in the urban area of Lagos and the other in the rural area of Ekiti state). A total of 214 healthy children (urban school = 118; rural school = 96). The survey was conducted online and on-site during the school hours. The data were analysed using frequency count, percent, mean, standard deviation, and independent t-test at p < 0.05 level of significant. Results The result of the t-test showed that there are significant differences in the weekly consumption of soft drinks (p = 0.02), fizzy drinks (p = 0.00), sugary snacks (p = 0.00) and the consumption of fish (p = 0.00) by the rural and urban schoolchildren. Conclusions and recommendations Based on the results, it was concluded that most of the children were relatively well fed with moderately healthy dietary choices. Urban children are making healthy dietary choices and few unhealthy choices. However, rural schoolchildren are making healthy dietary choices relative to affordable options. The government to urgently bridge the nutritional gap between urban and rural schoolchildren through food market intervention and school nutrition campaign.

Abstract
BACKGROUND The purpose of this study was to examine whether extended use of a variety of screen-based devices, in addition to television, was associated with poor dietary habits and other health-related characteristics and behaviors among US adults. The recent phenomenon of binge-watching was also explored. METHODS A survey to assess screen time across multiple devices, dietary habits, sleep duration and quality, perceived stress, self-rated health, physical activity, and body mass index, was administered to a sample of US adults using the Qualtrics platform and distributed via Amazon Mechanical Turk (MTurk). Participants were adults 18 years of age and older, English speakers, current US residents, and owners of a television and at least one other device with a screen. Three different screen time categories (heavy, moderate, and light) were created for total screen time, and separately for screen time by type of screen, based on distribution tertiles. Kruskal-Wallis tests were conducted to examine differences in dietary habits and health-related characteristics between screen time categories. RESULTS Aggregate screen time across all devices totaled 17.5 h per day for heavy users. Heavy users reported the least healthful dietary patterns and the poorest health-related characteristics - including self-rated health - compared to moderate and light users. Moreover, unique dietary habits emerged when examining dietary patterns by type of screen separately, such that heavy users of TV and smartphone displayed the least healthful dietary patterns compared to heavy users of TV-connected devices, laptop, and tablet. Binge-watching was also significantly associated with less healthy dietary patterns, including frequency of fast-food consumption as well as eating family meals in front of a television, and perceived stress. CONCLUSIONS The present study found that poorer dietary choices, as well as other negative health-related impacts, occurred more often as the viewing time of a variety of different screen-based devices increased in a sample of US adults. Future research is needed to better understand what factors among different screen-based devices might affect health behaviors and in turn health-related outcomes. Research is also required to better understand how binge-watching behavior contributes impacts health-related behaviors and characteristics.

Abstract
Iodine deficiency (ID) in women of childbearing age remains a global public health concern, mainly through its impact on fetal and infant neurodevelopment. While iodine status is improving globally, ID is still prevalent in pregnancy, when requirements increase. More than 120 countries have implemented salt iodisation and food fortification, strategies that have been partially successful. Supplementation during pregnancy is recommended in some countries and supported by the WHO when mandatory salt iodisation is not present. The UK is listed as one of the ten countries with the lowest iodine status globally, with approximately 60 % of pregnant women not meeting the WHO recommended intake. Without mandatory iodine fortification or recommendation for supplementation in pregnancy, the UK population depends on dietary sources of iodine. Both women and healthcare professionals have low knowledge and awareness of iodine, its sources or its role for health. Dairy and seafood products are the richest sources of iodine and their consumption is essential to support adequate iodine status. Increasing iodine through the diet might be possible if iodine-rich foods get repositioned in the diet, as they now contribute towards only about 13 % of the average energy intake of adult women. This review examines the use of iodine-rich foods in parallel with other public health strategies, to increase iodine intake and highlights the rare opportunity in the UK for randomised trials, due to the lack of mandatory fortification programmes.

Abstract
There is growing policy interest in encouraging better dietary choices. We study a nationally-implemented policy - the UK Healthy Start scheme - that introduced vouchers for fruit, vegetables and milk. We show that the policy has increased spending on fruit and vegetables and has been more effective than an equivalent-value cash benefit. We also show that the policy improved the nutrient composition of households' shopping baskets, with no offsetting changes in spending on other foodstuffs.

Abstract
Despite several decades of decline, cardiovascular diseases are still the most common causes of death in Western societies. Sedentary living and high fat diets contribute to the prevalence of cardiovascular diseases. This paper analyses the trade-offs between lifestyle choices defined in terms of diet, physical activity, cost, and risk of cardiovascular disease that a representative sample of the population of Northern Ireland aged 40-65 are willing to make. Using computer assisted personal interviews, we survey 493 individuals at their homes using a Discrete Choice Experiment (DCE) questionnaire administered between February and July 2011 in Northern Ireland. Unlike most DCE studies for valuing public health programmes, this questionnaire uses a tailored exercise, based on the individuals' baseline choices. A "fat screener" module in the questionnaire links personal cardiovascular disease risk to each specific choice set in terms of dietary constituents. Individuals are informed about their real status quo risk of a fatal cardiovascular event, based on an initial set of health questions. Thus, actual risks, real diet and exercise choices are the elements that constitute the choice task. Our results show that our respondents are willing to pay for reducing mortality risk and, more importantly, are willing to change physical exercise and dietary behaviours. In particular, we find that to improve their lifestyles, overweight and obese people would be more likely to do more physical activity than to change their diets. Therefore, public policies aimed to target obesity and its related illnesses in Northern Ireland should invest public money in promoting physical activity rather than healthier diets.
