Assessing environmental impact of different products and sources is not only about waste management. It is important to protect our oceans, but a real assessment of environmental impact needs a Life Cycle Assessment. The authors of this study compared different types of straws (Polypropylene plastic, Stainless Steel, Glass, Paper, Bamboo and Wheat stem) and looked at marine litter, climate change, ozone depletion, respiratory inorganics, photochemical ozone formation, acidification, water depletion, land use, resource consumption, eutrophication, energy demand, human toxiticy, and freshwater ecotoxicity. Plastic fares pretty badly, especially if they are not disposed of through appropriate facilities. In this study, environmental impact depends largely on the production methods, and it is still considered to take 100 years to degrade. However, new techniques (adopted by Persometrics) allow for edible straws to be produced and is made from a byproduct material that would otherwise be discarded. We have further tested its validity in salivary hormone testing.

Early life stress has an impact on how the Hypothalamic Pituitary Adrenal (HPA) axis develops during puberty. The associations between inter-related HPA-dependent hormones are here found to depend on severity of stress before puberty. The study sheds light on the development of the HPA axis and factors influencing Cortisol/DHEA-s relations, important for our Extended Stress Report.

In this secondary analysis of a national, longitudinal cohort study, households that took part in Waves 8 or 9 of the UK Household Longitudinal Study (UKHLS) panel, including all members aged 16 or older in April, 2020, were invited to complete the COVID-19 web survey. Mental health was assessed using the 12-item General Health Questionnaire (GHQ-12). More than 50,000 individuls took part in the study, which showed that clinically significant levels of mental distress rose from pre-COVID times, from 18·9% to 27·3%, one month into UK lockdown. Mean GHQ-12 score also increased over this time, from 11·5 to 12·6 (12·5–12·8) in April, 2020. Perform the General Health Questionnaire (GHQ-12) here.

From the abstract: this study investigates modifications and relationship between physiological stress markers after a preseason period between elite footballers. Twenty-four elite soccer players participated in this study. Physical load, mood, morning and evening concentrations of cortisol and testosteronewere all measured. Cortisol is strongly associated with mood. A decrease in testosterone to cortisol ratio of more than 30% indicates incomplete recovery, residual fatigue, and impaired competitive performance. Since the change was non-existent in these players, this suggests that the players had adequate coping with the stresses of training.

The purpose of this study is to analyze the internal consistency, factor structure, and external validity of the 12-item General Health Questionnaire (GHQ-12) among older adults in India. Settings and Design: This study analyzes data collected as part of the UNFPA »Building Knowledge Base on Ageing in India (BKPAI)» project. The BKPAI Survey was conducted in 2011 in seven major demographically advanced states of India - Himachal Pradesh, Punjab, West Bengal, Odisha, Maharashtra, Kerala, and Tamil Nadu. Materials and Methods: A community-based representative sample of 9692 respondents aged 60 and above from seven Indian states was employed. The GHQ-12 questionnaire was administered. Statistical Analysis: The Cronbach's alpha was calculated to analyze internal consistency. Factor analysis was applied to explore the factor structure of GHQ-12, and then correlation coefficients were calculated to examine the external validity of the measurement. Results: The Cronbach's alpha of the GHQ-12 is 0.9. Factor analysis reveals two significant components which accounted for 59% of the variance. The correlation between the overall score of GHQ-12 and the subjective well-being inventory (SUBI) is 0.58. Conclusions: The GHQ-12 shows adequate reliability among the older population in India.

Researchers at Kennesaw University and Hofstra University studied changes in cortisol, testosterone and their ratio in function of workout intensity and in function of time points leading up to a competition. Crossfit (R) was used to achieve High-Intensity Functional Training. Findings point to the importance for athletes and coaches of monitoring these hormones (and above all their ratio) when seeking consistency of workouts.

The study conducted by Eran Segal and colleagues at the Weizman institute suggests that we are asking the wrong question when searching for the right diet and should instead be looking for individualised diets. The researchers used blood sugar spikes as a biomarker for food reactivity and followed some 800 participants longitudinally showing that people differ in their response to food stuffs. An experimental follow-up (diet-intervention) confirmed: the one and same food could have opposite spike patterns for two people. Persometrics finds this a compelling first step to individualised nutrition, and especially promising that the authors incorporate the microbiome in their research, which has been used for our stress reports and has also figured on our social media outlets.

Karine Spiegel, Rachel Leproult, Mireille L’Hermite-Balériaux, Georges Copinschi, Plamen d. Penev, and Eve van Cauter from Universities of Chicago and Brussels (ULB) investigated links between sleep quality (notably how long the participants were allowed to sleep: 4, 8 or 12 hours) and the endocrine system. Sleep restriction decreased leptin, and increased evening cortisol, even when people did not perceive the restriction as stressful. Showing that sleep may have an effect on appetite and in turn obesity. 12 hour slots (no sleep restriction) produced better biomarkers even though participants only slept just over 9 hours in average.

Taken together, we use this information in our guidance of stress reports and also for current development of our sleep reports.

This study was carried out by two of Persometrics's very own (hosted and funded by the Brain Mind Institute at the EPFL). Feel free to contact us for a copy. We showed that dominant males (as measured through questionnaires tapping the wish and propensity to seek to dominate others) are faster than their less dominant counter-parts. The speed advantage was shown in both behavioural tasks (of which there were a variety) and in physiological measurements (EEG). It is believed that this fast reaction time creates an advantage which is what leads men to be treated differently by others, in turn creating the dominant personality trait. We say dominant "men" because we did not study females, not because it does not apply to females. Questionnaire will be available on persometrics.com soon!

Twenty-eight Long-Evans rats followed plant-based or animal-based diets for 12 weeks, with or without exercise. Total circulating testosterone, estradiol, and body composition was then measured. Plant-based diets were associated with lowered fat accumulation, no difference in testosterone, at the same time as providing adequate nutrition for training in rats.

Boesch and colleagues at University of Zurich, ETH Zurich and University of Western Ontario, show a link between cortisol in hair and stress, humidity, temperature as well as socioeconomic factors and physiological data such as sweating. Stress through military trainig could not be detected in cortisol concentrations in hair, whereas meteorological data could predict some variance, showing that this technique is experimental and requires stringent control of external variables. Inter-subject factors predicted concentrations as well. Persometrics’s take is that this technique is best used to compare one’s own state across different times.

We value this research from Leiden University medical Center and Leiden University (NL) which shows that basal cortisol cannot predict burnout on large scale on its own, nor can the CAR predict burnout after the fact (which is what is shown in correlational studies).
