To assess trends in the dietary quality of Mexican adolescents from 2006 to 2018, both overall and by sociodemographic indicators, using adaptations of the EAT-Lancet Planetary Health (PH) recommendations, optimal intake estimated by the Global Burden of Disease (GBD) and 2015 Mexican Dietary Guidelines (MDG) in nationally representative samples.

Using dietary data from a semi-quantitative FFQ, dietary quality indexes were constructed as adaptations of three dietary intake recommendations. Trends in adherence to recommendations were evaluated with multivariate quantile regression models with survey year as the main independent variable and adjusted for age, sex, energy intake, dwelling area, geographical region, household assets condition, and student/non-student status. P values and CI were Bonferroni-corrected.

Mexico.

Non-pregnant or lactating adolescents aged 12–19 years (n 16 520).

Adherence to the PH index was about 40 %, GBD was nearly 35 % and MDG was about 37 %. The lowest adherences were for added sugars, sugar-sweetened beverages, nuts and seeds, red meats, processed meats, and legumes (<28 %). No 2006–2018 trends in total adherence were found in any index. Nevertheless, negative adherence trends were identified for poultry (β = –2·4), and saturated fats (β = –0·93), and positive for unsaturated oils (β = 1·23), in the PH. In MDG, relevant trends were found for plain water (β = 1·63) and foods rich in fats (β = –1·24).

Mexican adolescents have demonstrated poor dietary quality by these three approaches. Therefore, this population has a high-risk profile for diet-associated chronic diseases. Further research and appropriate public policies are needed.

Psychiatric in-patients have a greatly elevated risk of suicide. We aimed to examine trends in in-patient suicide rates and determine if characteristics of in-patients who died by suicide have changed over time.

We identified all in-patients in England who died by suicide between 2009 and 2020 from the National Confidential Inquiry into Suicide and Safety in Mental Health. Suicide rates were calculated using data from Hospital Episodes Statistics.

The rate of in-patient suicide per 100 000 bed days fell by 41.9% between 2009–2011 and 2018–2020. However, since 2016 the rate has remained static with no significant fall. Rates fell in men, those aged 30–59, and those with schizophrenia and other delusional disorders or personality disorder. Rates also fell for suicide by hanging (including hanging on the ward) and jumping. No falls were seen in suicide rates among women, younger and older age groups, and those with affective disorder. There was no indication of a transfer of risk to the post-discharge period or to home treatment/crisis care. More in-patients in the latter part of the study were aged under 25, were on authorised leave, and had psychiatric comorbidity.

In-patient suicide has significantly fallen since 2009, suggesting patient safety may have improved. The recent slowdown in the fall in rates, however, highlights that renewed preventative efforts are needed. These should include a greater focus on women, younger and older patients, and those with affective disorder. Careful reviews prior to granting leave are important to ensure a safe transition into the community.

To examine changes in the proportions of daily, weekly and occasional consumers of sugar-sweetened soda in six European countries that introduced/updated a tax between 2001–2002 and 2017–2018 and in neighbouring comparison countries (without a tax).

Repeated cross-sectional surveys.

Health Behaviour in School-aged Children study, spanning five survey years (school years 2001–2002 to 2017–2018).

Nationally representative samples of 13-year- and 15-year-old adolescents (n 236 623, 51·0 % girls).

Tax sizes (€0·02/l to €0·22/l) and pre-tax soda consumption were heterogeneous across countries. Prevalence of daily soda consumption reduced in the survey year following tax implementation in Latvia (from 17·9 to 11·9 %, P = 0·01), Finland (4·2 to 2·5 %, P = 0·001), Belgium (35·1 to 27·8 %, P < 0·001) and Portugal (17·4 to 14·9 %, P = 0·02), but not in Hungary (29·8 to 31·3 %, P = 0·47) or France (29·4 to 28·2 %, P = 0·27). However, reductions were similar (Finland) or smaller (Belgium, Portugal) than those in the comparison countries, except in Latvia where the reduction was larger (Pinteraction < 0·001). Prevalence of weekly soda consumption remained stable (Finland, Hungary and France) or increased (Latvia, Belgium); only Portugal experienced a decline (P < 0·001), which was larger than in the comparison country (Pinteraction < 0·001). Prevalence of occasional soda consumption (<1x/week) did not rise after implementation of the tax in Latvia, Finland, Hungary, France or Belgium, or the rise was similar to the comparison country in Portugal (Pinteraction = 0·15).

Countries with a soda tax did not experience larger beneficial changes in post-tax adolescent consumption frequency of soda than comparison countries. Further studies, with different taxation types, are needed in the adolescent population.

Psychiatry is not immune to the effects of trends and fads, which are ideas that elicit short-lived enthusiasm, are quickly adopted, and abandoned when they fail to live up to expectations. Trends meet a deeply felt need to explain, or at least name, what would alternatively be unexplainable human suffering.

The authors aim to explore the trends and fads that have occurred in psychiatric diagnostic and treatment throughout history and assess if any modern trends can be identified as well as assessing the effects or consequences of these.

The authors conducted a non-systematized literature review with focus on those articles most pertinent to the topic in question.

The literature demonstrates that fads and trends not only plague fashion and diet, but also psychiatry. Trends in psychotherapeutic options can be observed by the swing from psychoanalysis to psychopharmacological focus. Overdiagnosis is one of the consequences of these trends, and can be seen from hysteria, schizophrenia, multiple personality disorder, attention-deficit and hyperactivity disorder to gender identity disorder. These trends impact the way diagnosis are made and the treatments implemented.

Fads in psychiatry have occurred not only on the edge, but in the very mainstream of theory and practice. A balance is called for, with caution needed in order not to fall into the temptation of the fad, however, an open mind should also be maintained when cutting-edge treatments and theories emerge. The sensible antidote to falling for fads and trends in psychiatry is commitment to evidence-based medicine.

Congenital heart defects (CHD) are the most frequent group of congenital anomalies representing a significant burden of mortality and morbidity and health service load.

In the Northern Ireland population, served by a single paediatric cardiology centre, we determine the prevalence and trends of CHD among live births.

This is a descriptive cross-sectional population-based study, using the paediatric cardiology database. The study included a total of 245,120 live births representing all children born in Northern Ireland 2005-2014.

A total of 11,410 children (4.65% of live births in Northern Ireland) received an echocardiogram for suspected CHD, and 3,059 children were subsequently diagnosed with a major CHD (prevalence = 12.48 per 1,000 live births (95% CI 12.04–12.93)) of whom 490 (16.02%) had genetic or chromosomal disorders including Down syndrome. The prevalence of non-genetic or chromosomal cases was 10.48 per 1,000 live births (95% CI 10.08–10.89) and did not change significantly over time (p = 0.91). The prevalence of CHD diagnosed in the first year of life was 8.46 per 1,000 live births (95% CI 8.10–8.83), which increased over time (p < 0.01). The prevalence of severe CHD was 2.02 per 1,000 live births (95% CI 1.85–2.21).

Northern Ireland has a high prevalence of CHD among European countries, which may be associated with complete ascertainment of both early and late diagnosed cases recorded in the paediatric cardiology database, as well as being one of the few European countries where terminations of pregnancy for foetal anomaly was illegal during the study period.

To examine minimum dietary diversity (MDD) trends and determinants among children aged 6–23 months.

Secondary analysis of the Indonesia Demographic and Health Surveys (IDHS) between 2007 and 2017. The primary outcome was MDD, the consumption of at least five out of eight food groups (MDD-8). We included a total of 5015 (IDHS 2007), 5050 (IDHS 2007) and 4925 (IDHS 2017) children aged 6 to 23 months to estimate trends of MDD-8 and to identify factors associated with MDD-8. We used multiple logistic regression analysis adjusted for the complex sampling design to investigate the association between the study factors and MDD-8.

Indonesia.

A total of 14 990 children aged 6–23 months.

Over the 10 years, the percentage of children who consumed a diversified diet was 53·1 % in 2007, 51·7 % in 2012 and 53·7 % in 2017. Multivariate analyses showed that older age children, higher maternal education, maternal weekly access to media, paternal non-agricultural occupation, history of at least four antenatal care visits and wealthier households were associated with the increased odds of MDD-8. Children living in rural areas, Sulawesi and Eastern Indonesia, were less likely to eat a diversified diet.

The proportion of children meeting MDD-8 has stagnated in the last decade. Child, parental, health care, household and community factors are associated with MDD-8. Therefore, nutrition education programmes and behaviour change communication activities should target mothers and families from socio-economically and geographically disadvantaged populations.
