Siinviidatu leidis oma koha kahel peamisel põhjusel: (1) impulsiivsus mängib olulist rolli tänapäeva võimaluste- ja nügimisterohkes sotsiaalses maailmas; (2) Eesti andmestikul põhinev empiiria võiks huvi pakkuda kõikidele eesti keelt kõnelevatele. Ja, mõistagi, tunnustus autoritele!

Kontekstiks: mis on impulsiivsus?

“Impulsivity is “a range of actions which are poorly conceived, prematurely expressed, unduly risky or inappropriate to the situation and that often result in undesirable consequences” (Daruna and Barnes, 1993).” (Matrov et al., 2022, p. 2)

Impulsiivsuse kasutusväli siinses tekstis:

“In the current study, however, we follow the concept of Dickman (1990) and Hans Eysenck (Eysenck, 2004) by parsing impulsivity into dysfunctional and functional dimensions. The social and personal consequences of the dysfunctional impulsive actions are usually negative, whereas manifestations of functional impulsivity are mostly beneficial.” (Matrov et al., 2022, p. 2)

Toiduvalikud ja füüsiline aktiivsus:

“Food choices and levels of physical exercise are manifestations of personality and decision-making that, in turn, affect biochemistry and formation of behavioral habits. In practical terms, as both nutrition and physical exercise affect brain neurochemistry, they can be considered as auxiliary tools to pharmacological methods for controlling excessive impulsivity.” (Matrov et al., 2022, p. 2)

“Food habits and preferences were usually assessed by some type of survey rather than asking participants to keep diaries of the actual daily food intake. We identified 1 representative longitudinal cohort study that was part of the French NutriNet-Santé project conducted on a large sample of adult volunteers (Bénard et  al., 2019).” (Matrov et al., 2022, p. 3)

“We aimed to ascertain a possible longitudinal association between adaptive and maladaptive impulsivity dimensions and dietary intake. We expected that such associations would not be strong, but possible, as certain types of eating disorders and food choices have been previously associated with impulsivity.” (Matrov et al., 2022, p. 3)

Andmeallikad ja andmete kogumine:

“In brief, all schools of Tartu County, Estonia, that agreed to participate (54 of the total of 56) were included in the sampling, and 25 schools were selected to sample at least 1000 participants in total. All children from grades 3 (younger birth cohort, aged 9 years) and grades 9 (older birth cohort, aged 15 years) were invited to participate. Follow-up studies included in this paper took place in 3 waves at ages: 15  years (n = 483), 18 years (n = 454), and 25 years (n = 440) for the younger birth cohort and at ages 18 years (n = 461), 25 years (n = 541), and 33 years (n = 504) for the older birth cohort. The first proper impulsivity data were collected in the year 2001 for the older and 2004 for the younger cohort.” (Matrov et al., 2022, p. 3)

Lugemishuvi suurendamiseks:

“However, our goal was to measure everyday manifestations of impulsivity rather than concentrate on clinical pathology. Such an approach is rooted in the understanding that impulsivity is a multifaceted phenomenon that spans the continuum from calculated risk-taking and adventurousness to pathological, harmful to the subject manifestations of impulsiveness (Evenden, 1999; Whiteside and Lynam, 2001; Strickland and Johnson, 2021).” (Matrov et al., 2022, p. 7) […] “Both dimensions of impulsivity declined with age and showed sex dependence: adaptive impulsivity scores were higher among males, and maladaptive impulsivity scores were higher among females.” (Matrov et al., 2022, p. 8) […] “The only positive association that all 3 modeling approaches agreed on was with vitamin B6. This possibly means that the adaptive impulsivity dimension is less related to specific, especially unhealthy, eating habits.” (Matrov et al., 2022, p. 8)
