This study aims to examine the different aspects of socio-economic status (SES) patterns in mental health from adolescence into adulthood by investigating the mean, prevalence, cumulative incidence and trajectories of several mental health measures, including depressive symptoms, mental disorder diagnosis and medication use. The different aspects of SES are investigated through the measures of subjective social status (SSS) in school, SSS in society, income and parental educational level.
Methods
Individuals born in 1989 were followed from 2004 to 2021 with surveys at ages 15, 18, 21, 28 and 32 years, supplied with yearly register data. The mean level of depressive symptoms, yearly prevalence of medication use and cumulative incidence of mental disorder diagnosis were calculated for each SES group (low, middle and high) across each measure. Group-Based Trajectory Modelling (GBTM) was used to identify depressive symptom trajectories and logistic regressions were used to analyse the relative odds ratios (ROR) of membership to the different trajectory groups by characteristics.
Results
Individuals with low SES at age 15 years across all SES measures showed higher mean depressive symptoms, prevalence of medication use and cumulative incidence of mental disorder diagnosis through adolescence and adulthood (age 15–32 years). Four depressive symptom trajectories were identified: low stable, moderate stable, decreasing and increasing trajectories. Being female, receiving medication or a mental disorder diagnosis in early adulthood and during the study period, having low SSS in school, parents not living together, being bullied, lacking support from teachers or classmates, lower levels of parents’ support or higher school pressure resulted in higher RORs of membership to the other trajectory groups compared to the low stable trajectory, while having high SSS in society resulted in a lower ROR.
Conclusions
This is the first study to detect the role of social support in relation to depressive symptom trajectories. While individuals with low social status consistently experienced more negative mental health outcomes than those with middle and high social status in the study period (age 15–32 years), low SSS showed the strongest associations. This indicates that SSS may capture vulnerable individuals not identified by traditional SES. Being female, having low SES, low social support, and other mental health outcomes were associated with higher odds of being in trajectories with more depressive symptoms. Preventive initiatives should therefore target individuals with such characteristics. It is worth exploring whether adolescents with increasing depressive symptoms could benefit from increased social support.
No one needs a tracheostomy tube only for being too weak to breathe, that is, for people with ventilatory pump failure. Noninvasive ventilatory support is safer, better tolerated and better maintains quality of life than does ventilatory support via tracheostomy. People at any age can become continuously dependent on (noninvasive) ventilatory support (CNVS) without ever going to a hospital or developing acute respiratory failure. People who depend on CNVS are more safely managed in their homes by trained care providers than in institutions or hospitals where supplemental oxygen therapy can result in acute respiratory failure. Here we discuss the management with respect to noninvasive ventilation or noninvasive ventilatory support for patients with ventilatory pump failure and discuss mechanical insufflation-exsufflation, intubation and extubation criteria for these patients.
Coughing is essential for survival as it clears secretions and foreign bodies from the central airways. Insufficient cough flows and aspiration of saliva are frequent problems in neurological illness and lead to tracheobronchial retention of secretions. Comorbidities like chronic obstructive pulmonary disease, certain medications and failure to adequately humidify the lower airways can lead to hypersecretion, thick and tenacious secretions and ciliary dysfunction, respectively. This can further aggravate any bronchopulmonary retention of secretions, finally leading to atelectasis, pneumonia, respiratory failure as well as death. Noninvasive ventilatory support is effective only if accompanied by adequate management of secretions. This chapter provides a comprehensive overview of the neuronal control, physiology and pathophysiology of coughing and bronchopulmonary retention of secretions as well as effective techniques to reduce secretions and to eliminate them from the airways.
Loneliness may lead individuals to spend more time on the internet and increase the likelihood of experiencing internet-use disorders. Similarly, individuals with internet-use disorders may feel lonelier. In the present systematic review and meta-analysis, pre-registered in PROSPERO (CRD42023390483), we quantified associations between internet-use-disorder symptoms (e.g. internet gaming disorder and online gambling disorder) and loneliness. We searched PubMed, Web of Science, and an institutional database aggregator for references that compared degrees of loneliness in groups of individuals with and without symptoms of internet-use disorder. Means and standard deviations of loneliness, or alternatively, odds ratios, were transformed into Cohen’s d for statistical pooling through a random-effects model. After screening 2,369 reports, we extracted data from 23 studies. The total number of individuals across the studies was 36,484. Participants were between 13 and 30 years of age (median 20). The pooled difference between those with and without internet-use-disorder symptoms yielded a standardized effect (Cohen’s d) of 0.53 (95% CI 0.35–0.7). While heterogeneity was high, there was no indication of publication or small sample biases. Similar effect sizes were found when limiting to specific types of internet-use disorder symptoms. Moreover, meta-regressions did not show an effect of age, sex, or sample size. Individuals with symptoms of internet-use disorders scored 49.35 (43.84–54.85) points on the UCLA-Loneliness scale on average, compared to 43.78 (37.47–50.08) in individuals without symptoms of internet-use disorders (Standardized Mean Difference: 5.18, 95% CI = 2.05–8.34). Individuals with internet-use-disorder symptoms experience greater loneliness. The effect appears moderately sized.
Since India had been controlled by the British, it regressed to a lower stage. Poverty had been a lived reality for Indians, including for some of the Indian economists, since the late seventeenth century. International trade networks were disrupted by economic crisis and wars. Meanwhile, the Indian subcontinent was experiencing some of the most severe famines in its history. The Indian economists felt these crises sweeping their cities and villages. In particular, Dadabhai Naoroji and Romesh Chunder Dutt would spend most of their adult lives examining the regress that they saw in India. They would explore how it could be measured, how it varied from region to region, and its causes.
India experienced several turbulent decades after the official takeover by the British Crown, following the Indian Mutiny, in 1858. Becoming an official territory of the British Empire came with promises of progress. Already by the 1870s, though, the promises seemed hollow. The textile industry, once a flourishing sector that supplied fabrics to most of the world, was dwindling. The average Indian was sinking into deeper poverty. And millions died in the three largest famines of India’s history between 1873 and 1901. It goes without saying that India’s large territory, rich history and its dependent position within the British Empire rendered its context dense and complex. India was extensively linked to the global economy and had a long history of trading in the subcontinent, primarily in textiles during the Mughal period, and later as one of the main suppliers of raw materials to the growing textile industry in Manchester in northern England. This chapter aims to contextualise the first generation of modern Indian economists by identifying the major trends and events affecting India in the past four decades of the nineteenth century.
Some ideas get less attention than others. And as much as intellectuals may want to believe that an idea spreads, and only spreads, if it gets us closer to the truth, that is not the only reason an idea may be taken up and circulated. An intellectual’s class, caste, gender, nationality, physical location, time period and so forth radically affects whether the knowledge they produce will be read, accepted and passed on. Knowledge creation, in modern science and especially economics, is notoriously focused on western European and North American intellectuals. There seems, in other words, to be boundaries that define who can produce knowledge. I have questioned those boundaries throughout this book, to uncover marginalised economists that are seldomly analysed. The first generation of modern of Indian economists is a good example of marginalised thinkers. They worked within an imperial setting and were treated as inferior, while their addressees, mainly British, were considered superior. The Indian economists were thus producing economic knowledge from the margins. As such, the Indian economists often got – and still get – labelled as copiers of existing knowledge from Europe and North America. The imperialist context created a blindness to original Indian thought. Within the history of ideas, and more specifically the history of economics, studies are predominately about well-known figures such as Adam Smith and David Ricardo, while lesser-known figures are rarely cited or analysed. Expanding the history of economics, which this book is only one example, provincialises well known economic theories like economic development and provides perspectives often either ignored or critiqued and quickly forgotten. Relocating Development Economics exposes new ideas not previously taken seriously.
Indian Economics’ global development plan in the long run was universal industrialisation and free trade. The widely accepted plan for development in the nineteenth century was broadly based on David Ricardo’s comparative advantage model, which prescribed industrialisation for western Europe and condemned the rest of the world to producing raw materials. This international division of labour, argued Mahadev Govind Ranade, would not, like the model theorised, bring Indians the highest level of progress. Indian Economics envisaged a positive-sum game of global development where an industrialised Asia would not outcompete the already industrialised western Europe. Industrialisation in India would bring higher standards of living and increase global aggregate demand, leading people to buy more goods from Britain and other industrialised countries. Universal industrialisation would, argued the Indian economists, be win–win for the world economy.
In the 1870s, a generation of economists was born amid a troubling reality in India. The country faced many crises around this time – suffering some of the worst famines in its history, having an imperial administration that struggled to balance its budget, and the crumbling of its textile industry, to name but a few. Indian Economics, argued its founder, Mahadev Govind Ranade, in 1892, would create economic knowledge that explained India’s distinct problems and would find appropriate solutions. The first generation of modern Indian economists had been convinced that India was different. But they used their difference for other ends. By contrast, they intended to prove India’s difference in such a way as to render its economy, institutions and people visible. From the 1870s there had been an increase in the number of Indians studying and informing their imperial rulers about conditions in the country. This first generation of modern Indian economists started to study their economy from new perspectives. Ranade’s and Ganapathy Dikshitar Subramania Iyer’s founding texts of Indian Economics bundled the studies that started to come in the 1870s with a common goal of progress and placed future studies under the intellectual umbrella of Indian Economics.
The first generation of modern Indian economists in the late nineteenth century became known as the Early Nationalists, as they began India’s fight for independence. When historians and political theorists analyse them, they often portray them as political scientists and nation-builders who mostly regurgitated existing European economic thinking. Much less has been written on their contribution to economics, despite them being the first generation of modern economists in India. This book shows how they produced original, forward-thinking knowledge on economic development. The intention is not to define development a priori, but to use development as an overarching focus to tease out the concepts, theories, models and policy prescriptions that the first generation of modern Indian economists studied and disseminated, and to bring these Indian economists into the global debate around what progress and development mean. This book places these economists into the history of economics and offers economic historians new sources on the Indian economy at the end of the nineteenth century. The book explores their understanding of how India’s economy evolved, their prescriptions for bringing progress back to India, the economic consequences of imperialism, and a global plan for development. By relocating development economics to another time and space, the book uncovers new variations on the idea of development.
Indian Economics’ short-term development plan aimed to harness progress in the two main sectors of the economy – industry and agriculture. The peasants, factory workers and merchants needed specific policies to aid them in growing their crops, manufacturing their products and selling their goods, respectively. India needed agricultural production of raw materials, industrial production using raw materials, and distribution of the finished manufactured products. Indian Economics prescribed a balanced growth strategy, seen later in India’s post-independence five-year plans, the first of which was implemented by Jawaharlal Nehru (1889–1964) from 1951 to 1956.
