“…Since total caffeine intake has been relatively stable over the past 10 years, adolescents may be replacing more traditional sources of caffeine with energy drinks. Energy drink consumption in New Zealand was lower than among Icelandic 15-year-olds (47%) [ 24 ] but higher than among Korean middle and high school students (23.9%) [ 27 ]. Energy drink intake has been associated with risky or negative health behaviour, including sensation seeking, poor sleep patterns, smoking, and use of alcohol and illicit drugs [ 28 , 29 , 30 ].…”

Adolescents may be particularly vulnerable to the effects of caffeine due to a lack of tolerance, their small size, changing brain physiology, and increasing independence. Concerns about adolescent caffeine consumption relate to potentially serious physiological and psychological effects following consumption. Motivations driving caffeine intake are not well understood among adolescents but are important to understand to reduce harmful behavioural patterns. This study explored caffeine consumption habits (sources, amount, frequency) of New Zealand adolescents; and factors motivating caffeine consumption and avoidance. The previously validated caffeine consumption habits questionnaire (CaffCo) was completed by 216 participants (15–18 years), with most (94.9%) consuming at least one caffeinated product daily. Chocolate, coffee, tea, and kola drinks were the most consumed sources. The median caffeine intake was 68 mg·day−1. Gender (boy) and being employed influenced the source, but not the quantity of caffeine consumed. One-fifth (21.2%) of adolescents consumed more than the recommended European Food Safety Authority (EFSA) safe level (3 mg·kg−1·day−1). Taste, energy, and temperature were the main motivators for consumption, and increased energy, excitement, restlessness, and sleep disturbances were reported effects following caffeine consumption. This study provides information on caffeinated product consumption among New Zealand adolescents, some of whom consumed caffeine above the EFSA safe level. Public health initiatives directed at adolescents may be important to reduce potential caffeine-related harm.

Background: The purpose of this study was to investigate the association between coffee, green tea, and soda drink intake and the risk of osteoporosis using data from the Korean Genome and Epidemiology Study (KoGES). Methodology: Data for patients with osteoporosis (n=11,484) and controls (n=156,320) were extracted using a national cohort study with KoGES Health Examiner (HEXA) data of participants over 40 years of age. We then analyzed the history of coffee/green tea/soda drink intake frequency at baseline from 2004 to 2013 and follow-up data from 2012 to 2016. Results: Regardless of the frequency of coffee intake, coffee intake showed lower odds ratios (ORs) for osteoporosis compared to the non-intake group, but not green tea and soda drink intake did not. According to the subgroup analysis by age and sex, coffee intake showed a lower ORs for osteoporosis in the both group of women age < 53 years of age and ≥ 53 years of age regardless of the frequency of coffee intake. Conclusion: The conclusion of this study was that coffee intake was associated with lower incidence of osteoporosis in Korean women over 40 years of age, regardless of age.
