Special Issue Information

Dear Colleagues,

Both nutrition and work are fundamental aspects of life. We spend one-third of our lives working. There are countless articles on nutrition and the same is true for work. However, despite the fact that nutrition and work are intrinsically linked, there is very little data available considering both nutrition and work together.

We would like to invite articles on the relationship between diet and work. This may include the impact of work on diet, diet quality, food and/or nutrient intake, nutritional biomarkers, and nutritional status, as well as the impact of nutrition or specific diets on work, working performance, economic impacts, or health in workers.

We also invite articles on dietary interventions in the workplace. Dietary interventions could be diverse, from general incitation through the internet or company campaigns to targeted nutritional preventive strategies for some specific workers.

Nutrition and Work has emerged as an important area of research. We hope that this Special Issue will provide evidence for dietary recommendations and best practices for some specific working conditions. For example, many working conditions imply high physical demand, and putatively high energy expenditure. Another example is working in high-temperature conditions (sometimes above 50°C), which requires adaption of water or liquid intake.

Any design is accepted, including cross-sectional or longitudinal studies, from observational to interventional studies. Studies can be randomized or not, controlled or not, but all studies must be related to the topic “Nutrition and Work”. Systematic reviews and meta-analyses are very welcome. We may also accept case reports when they generate some new perspectives.

We welcome any collaborative articles between disciplines, from medicine to physiology or psychology, mathematical modeling, engineering, or further specialties, as long as the topic is related to the theme of our Special Issue “Nutrition and Work”.

Abstract

Despite the available literature on the consequences of night shiftwork on stress and food intake, its impact on leptin and ghrelin has never been studied. We previously demonstrated that leptin and ghrelin were biomarkers related to stress, and acute stress-induced a decrease in leptin levels and an increase in ghrelin levels. We performed a prospective observational study to assess the influence of night work, nutrition, and stress on the levels of ghrelin and leptin among emergency healthcare workers (HCWs). We took salivary samples at the beginning of a day shift and/or at the end of a night shift. We also monitored stress using the job demand-control-support model of Karasek. We recorded 24-h food intake during the day shift and the consecutive night shift and during night work and the day before. We included 161 emergency HCWs. Emergency HCWs had a tendency for decreased levels of leptin following the night shift compared to before the dayshift (p = 0.067). Furthermore, the main factors explaining the decrease in leptin levels were an increase in job-demand (coefficient −54.1, 95 CI −99.0 to −0.92) and a decrease in job control (−24.9, −49.5 to −0.29). Despite no significant changes in ghrelin levels between shifts, social support was the main factor explaining the increase in ghrelin (6.12, 0.74 to 11.5). Food intake (kcal) also had a negative impact on leptin levels, in addition to age. Ghrelin levels also decreased with body mass index, while age had the opposite effect. In conclusion, we confirmed that ghrelin and leptin as biomarkers of stress were directly linked to the job demand-control-support model of Karasek, when the main cofounders were considered.

Abstract

Malaysia has been experiencing smoke-haze episodes almost annually for the past few decades. PM_2.5 is the main component in haze and causes harmful impacts on health due to its small aerodynamic size. This study aimed to explore the implications of PM_2.5 exposure on the dietary intake of working individuals. Two phased 13-weeks follow-up study was conducted involving 440 participants, consisting of two cohorts of outdoor and indoor workers. Ambient PM_2.5 concentrations were monitored using DustTrakTM DRX Aerosol Monitor. Data on Simplified Nutritional Appetite Questionnaire (SNAQ) and 24 h diet recall were collected weekly. The highest PM_2.5 concentration of 122.90 ± 2.07 µg/m³ was recorded in August, and it vastly exceeded the standard value stipulated by US EPA and WHO. SNAQ scores and calorie intake were found to be significantly (p < 0.05) associated with changes in PM_2.5 exposure of outdoor workers. Several moderate and positive correlations (R-value ranged from 0.4 to 0.6) were established between SNAQ scores, calorie intake and PM_2.5 exposure. Overall findings suggested that long hours of PM_2.5 exposure affect personal dietary intake, potentially increasing the risk of metabolic syndromes and other undesired health conditions. The current policy should be strengthened to safeguard the well-being of outdoor workers. Full article

Abstract

The COVID-19 pandemic and subsequent lockdowns modified work environments, lifestyles, and food consumption. Eating habits and mood changes in a French population during the first lockdown were examined using an online self-reported questionnaire with REDCap software through the COVISTRESS.ORG website. In 671 French participants, the main changes during lockdown were increased stress levels (64 [23; 86] vs. 3 [0; 18]) and sedentary behavior (7 [4; 9] vs. 5 [3; 8] hours per day), a deterioration in sleep quality (50 [27; 83] vs. 70 [48; 94]) and mood (50 [30; 76] vs. 78 [50; 92]), and less physical activity (2.0 [0.5; 5.0] vs. 3.5 [2.0; 6.0]). Mood was modified, with more anger (56 [39; 76] vs. 31 [16; 50]), more sadness (50 [34; 72] vs. 28 [16; 50]), more agitation (50 [25; 66] vs. 43 [20; 50]), and more boredom (32 [7; 60] vs. 14 [3; 29]). A total of 25% of the participants increased their consumption of alcoholic beverages, 29% their consumption of sugary foods, and 26% their consumption of cocktail snacks. A multiple-correspondence analysis highlights four different profiles according to changes in eating habits, food consumption, lifestyle, and mood. In conclusion, eating habits and lifestyle changes during lockdown periods should be carefully monitored to promote healthy behaviors. Full article

Abstract

Return to work negatively affects the initiation and duration of breastfeeding. Our study’s objective was to assess the percentage of departments in Auvergne with an appropriate space for pumping milk at work. Our cross-sectional survey investigated the arrangements for facilitating the continuation of breastfeeding on return to work at all departments at the Clermont-Ferrand University Hospital Center and perinatal (obstetric and pediatric) departments in this region. Our principal endpoint was the percentage of departments reporting that they had a lactation room—a room where nursing mothers can express milk—and whether it met the criteria defined by the French Labor Code. Among 98 respondents, 44 departments (44.9%) did not offer lactation rooms; of the remaining 54 departments, only 11 rooms met the legal requirements. All perinatal departments offered lactation rooms. The availability of a lactation room was associated with other breastfeeding support, such as a break period for expressing milk (p < 0.0001) and the availability of a refrigerator to store it (p = 0.01). Almost half the responding departments did not offer a lactation room where mothers could breastfeed or pump their milk. Measures must be envisioned to facilitate the pumping of breast milk by French women returning to work. Full article

Abstract

Night shift workers experience circadian misalignment and sleep disruption, which impact hunger and food consumption. The study aim was to assess the impact of chronotype on hunger and snack consumption during a night shift with acute sleep deprivation. Seventy-two (36f, 36m) healthy adults participated in a laboratory study. A sleep opportunity (03:00–12:00) was followed by a wake period (12:00–23:00) and a simulated night shift (23:00–07:00). Subjective measures of hunger, prospective consumption, desire to eat fruit, and desire to eat fast food were collected before (12:20, 21:50) and after (07:20) the night shift. Snack opportunities were provided before (15:10, 19:40) and during (23:50, 03:30) the night shift. A tertile split of the dim light melatonin onset (DLMO) distribution defined early (20:24 ± 0:42 h), intermediate (21:31 ± 0:12 h), and late chronotype (22:56 ± 0:54 h) categories. There were no main effects of chronotype on any subjective measure (p = 0.172–0.975), or on snack consumption (p = 0.420), and no interactions between chronotype and time of day on any subjective measure (p = 0.325–0.927) or on snack consumption (p = 0.511). Differences in circadian timing between chronotype categories were not associated with corresponding differences in hunger, prospective consumption, desire to eat fruit, desire to eat fast food, or snack consumption at any measurement timepoint.

Abstract

Despite the consequences of night-shift work, the diet of night-shift workers has not been widely studied. To date, there are no studies related to food intake among emergency healthcare workers (HCWs). We performed a prospective observational study to assess the influence of night work on the diet of emergency HCWs. We monitored 24-h food intake during a day shift and the consecutive night, and during night work and the daytime beforehand. We analyzed 184 emergency HCWs’ food intakes. Emergency HCWs had 14.7% lower (−206 kcal) of their 24-h energy intake during night shifts compared to their day-shift colleagues (1606.7 ± 748.2 vs. 1400.4 ± 708.3 kcal, p = 0.049) and a 16.7% decrease in water consumption (1451.4 ± 496.8 vs. 1208.3 ± 513.9 mL/day, p = 0.010). Compared to day shifts, night-shift had 8.7% lower carbohydrates, 17.6% proteins, and 18.7% lipids. During the night shift the proportion of emergency HCWs who did not drink for 4 h, 8 h and 12 h increased by 20.5%, 17.5%, and 9.1%, respectively. For those who did not eat for 4 h, 8 h and 12 h increased by 46.8%, 27.7%, and 17.7%, respectively. A night shift has a huge negative impact on both the amount and quality of nutrients consumed by emergency healthcare workers. Full article
